Baby Monitor Set: Which one to choose?




Expecting





Answer
Your best choice would be the: Summer Infant D & N Handheld Color Video Baby Monitor

The price is approximately $140, and you get some great features like night vision capabilities, high quality sound and high quality color video. This unit will also transmit up to 350 ft, so you will never be out of range in your home.

Whats the best baby monitor?




Kelly Vibe


I am having my first child soon and would like a monitor that has good sound and picture quality day and night so i can make dinner ect and just look at my hand held monitor instead of going in the other room to see why he is making noise.


Answer
angel care, i get so much more rest knowing that angel care is monitoring my baby girl, it takes a little bit to get used to adjusting the sensitivity of the monitor so you dont get false alarms but its the best monitor out there, plus you can use it on into the toldler years when your kido sneaks out of bed the alarm will sound,

the alarm sounds if the monitor does not detect motion or breathing after 20 secs

there is not picture on this monitor but rather a motion detection system, when you go to sleep at night you know rather or not your baby is still moving and ok

will you pls show the block diagram of the baby monitor machine design?how it works?

Answer
Baby Monitor is BT's first entry into this market. Digital technology means crystal-clear sound quality and no interference. The Baby Monitor Plus has extra features in addition to the Baby Monitor, including an LCD, five lullabies and a temperature monitor. A range of up to 300 metres (in ideal conditions) and an Intercom feature means that a constant link is maintained between parent and baby.


WASHINGTON, D.C. - In cooperation with the U.S Consumer Product Safety Commission (CPSC), Gerry Baby Products Company, of Thornton, Colo., is announcing a voluntary recall of approximately 990,000 Model 602 Gerry Deluxe Baby Monitors. Wires inside the monitor may be improperly connected, resulting in the product overheating with the possibility of the monitor causing fire. Another contributing factor is when blankets or other bedding are placed around or on top of the monitor blocking ventilation.

Gerry urges consumers to read all product warnings and instructions accompanying all monitors. Consumers should not place any monitor in the crib, among blankets or bedding, or in any position that interferes with ventilation for the monitor.

Gerry is aware of one fire without injuries involving a Model 602 monitor with this manufacturing error. This information was brought to CPSC's attention by a member of the International Association of Arson Investigators (IAAI). In addition, CPSC has also received reports alleging Model 602 Baby Monitor involvement in two other fires, including one with a fatality and an injury, and 13 incidents of the monitors getting warm to the touch, including one skin burn. Gerry stated that only one report (no injuries) of these 16 claims was conclusively determined to have been caused by the Model 602 monitor.

The two-piece monitor sets resemble walkie-talkies. The monitors have pale gray and royal blue plastic casing. A red "on" light and a blue "Gerry" label appear on the front of each monitor. The back of the monitors are embossed with "GERRY DELUXE BABY MONITOR MODEL 602" and the manufacturer's date code. The date code appears as a circle of numbers, with an arrow pointing to the number of the month and the two-digit year number on either side of the arrow. This recall involves monitors with date codes "8806" (June 1988) through "9005" (May 1990).

Juvenile product and baby supply stores and department stores sold the recalled monitors nationwide from June 1988 through May 1990. The monitors were packaged in blue cardboard boxes labeled in part, "Gerry Deluxe Baby Monitor...Listen to Your Baby from any Home Location...Gerry Baby Safetronics..."

Consumers who own Model 602 monitors should contact Gerry toll-free at (800) 672-6289 for instructions on how to return the recalled monitors for a free replacement monitor. For more information, consumers should call Gerry, or write to the company at Attn: Building R-602 Recall, 1500 East 128th Avenue, Thornton, CO 80241.

The U.S. Consumer Product Safety Commission protects the public from unreasonable risks of injury or death from 15,000 types of consumer products under the agency's jurisdiction. To report a dangerous product or a product-related injury and for information on CPSC's fax-on-demand service, call CPSC's hotline at (800) 638-2772 or CPSC's teletypewriter at (800) 638-8270. To order a press release through fax-on-demand, call (301) 504-0051 from the handset of your fax machine and enter the release number. Consumers can obtain this release and recall information at CPSC's web site at http://www.cpsc.gov or via Internet gopher services at cpsc.gov.

baby monitors?




feminootie


i want to purchase a good quality baby monitor. what brand is best? what brand really sucks? i also don't want to spend a ton of money. thank you!
geez, sorry. i really only want to use it when he is sleeping and when i need to run to the kitchen or restroom. i live in an apartment. it's not that big.



Answer
With both my kids I got the Fisher Price Lights and Sounds monitor. I wanted to have 2 in case I needed them both. They have worked just fine for a few years and have never given us trouble. I tried a more expensive one once that had an intercom button and it interferred with the house alarm and stopped working. Returned it for the FP one which is not that expensive.

Can anyone recommend a good inexpensive baby monitor?




Allen





Answer
I am using Philips Avent. It was less than 100S$. I like it mostly bcz it's handy and cheap:p but the sound quality and quality in general is Awsome. It does eat alot of battery but it also comes with AC power. I could use it for like 15,20 days on battery life. But if you can spare two plugs then ur all good:) if the baby unit is turned off the parent unit makes a loud alaram... So u know that the baby unit has been turned off... It also indicates if the batteries are running out by a blinking red light in both units so u know before hand if u need to change batteries:) I hope it helps. Good luck:)

PS: it's 100 Singapore dollars.

Baby monitor - movement or video?




Kelsy


I dont need a sound monitor because the nursery will be right next door. Not sure which one to get the movement one for SIDS or the video one so you can see the baby at all times?


Answer
There's pro's and con's for each and most baby monitors will state on them that they aren't 100% accurate, especially the movement detectors for SIDS. There is no way a machine can work reliably 100% accurately on detecting movement to prevent SIDS.

If you're really worried about not being able to see your baby then I would opt for the video monitor so you can see him or her moving in the night and possibly see their chest rise and fall (depending on the quality of the image and light source).

I really need help deciding what surround sound Bose speaker system to get for my room?

best sound quality baby monitor
 on Baby Monitor Reviews | Best Baby Monitor
best sound quality baby monitor image



starbucks


I have about a 12 by 12 foot room. I want a high quality system with at least four speakers, including one bigger than the others.It needs to be wireless so I can play music from my computer. I also need to have a jack for my ipod to connect to.


Answer
If you want a high quality system then absolutely do not buy Bose. For the same price you spend on Bose, you can get a much better sound system. The only thing superior about Bose is their marketing.

Right now, I would say that JBL, Klipsch and Polk Audio are probably the 3 leading speaker companies that consumers such as yourself should be looking into. They all have equivalently priced products as Bose, but with superior sound in that price bracket.

Another thing I would like to try to talk you out of is a wireless system. So much stuff these days rely on wireless technology (cell phones, computers, keyless entry key chains, baby monitors, etc.) that you will often get interference and bleed-over into your wireless speakers. Cell phones can produce a popping noise while things like baby monitors can actually cause voices to be heard in the background, behind the music.

And since these wireless speakers are active, meaning that they have to be plugged into an AC outlet for power, they can also get interference from "dirty" or unstable power coming from your wall socket. Unstable power can be caused by electric motors such as refrigerator compressor pumps, washer and dryers, and more. So one minute you may be listening to some clean music and the next minute music with a fuzzy background noise because your refrigerator kicked on.

To prevent dirty power, you can buy power filters. Of course you would have to buy one for each speaker. The good thing is that most of these power filters have built-in surge protection (which you will also want). The bad thing is that they start at about $60 per filter. So if you bought a 5.1 style speaker system, you would need $360 just for filters.

So think about it. Do you really want to spend a grand or more on "quality" speakers just to have them play hissing and buzzing sounds just because you wanted a wireless system? I wouldn't. Take the time to run some wires and do the job right. You can't half ass quality.

And if some sales person says to you that you will not get this kind of interference, just remember, it's his job to tell you this.

As far as your sound system goes, to choose a nice one, you need to take a few things into consideration like:

1. What is your budget?
2. Will this be primarily for watching movies or for music?
3. How many speakers do I want? Specifically. 4 plus a sub woofer? 5 and a sub? This makes a big difference in price.

Once you have figured these things out, then your question can be better answered.

What is the best recording software for PC?




Oleg


I have tried multiple recording softwares and none seems suit me.

I want to start a YouTube channel, but they stop me in that.

- Bandicam, problem is (for me at least) bad sound quality.
- Fraps, huge file size.
- Dxtory, crashes my game when I attempt to record.
- BB FlashBack, it has lag, can't even handle the game.

So I'm looking for a good recording software to use for games like CoD, Minecraft, World of Wacraft and such. It would be good if it provided lower file size (as Bandicam), free if possible, good quality sound/video quality + provides me good FPS.

Thanks.



Answer
There are a number of good "Screen Capture" recording software.. the problem is, most games lag or show hesitations on 'screen capture' software.. especially if the game of high quality like "call of Duty"..

You can remedy these by having a really powerful computer:
pump up the ram to max, the graphic card to max and anything that makes a gaming computer better to max..

while keeping the quality of picture lower, like setting the game graphics to lowest settings, and the quality of recording to lowest settings with standard definition SD instead of high definition HD..

All of which will produce a poor quality video..

To improve the recording quality, you may consider lightweight, simple or less sophisticated Screen Capturing software that require less system resources (less memory, less processor power, etc..) like FastStone screen capture video recoder http://www.faststone.org/FSCaptureDetail.htm and CamStudio screen capture video recorder http://camstudio.org/ which are baby software in comparison with high-end expensive tools that may and may not work as you hope, like: Camtasia (the best software for screen capture video recorder) at http://www.techsmith.com/camtasia.html , Adobe Premier http://www.adobe.com/PremiereProâ and Corel VideoStudio at http://apps.corel.com/lp/emea/webinar/index.htmlâ ..

The problem is always that there is not enough resources for both high quality games and screen capture video recording especially if your computer is not up to the challenge..
and you may have to sacrifice the quality if you wish to use software to record the game..

The answer is going hardware.. what most gamers on YouTube do is set up a camera behind them while playing in front of the monitor or the TV screen..

YEAACH, I know.. but to produce HD quality picture, consider Hardware screen capturing devices.. and you'd need three things:
1⢠upgrading your Graphic card to the ones that support HDMI first (but read a bit about HDCP in Wikipedia http://en.wikipedia.org/wiki/Hdcp )..
2⢠buy a good Screen Capturing device.. my experience is with Hauppauge HD PVR http://www.hauppauge.com/site/products/data_hdpvr2plus-gaming.html
3⢠devices like Hauppauge require a second computer or a laptop to perform the actual recording, but it doesn't have to be a high end computer.. my old laptop 5 years old with no 3D graphic card can do just that.. (just borrow your friends' laptop for a while, I hope its not a big deal)..

See the picture below, and instead of the Xbox being connected to the Hauppauge device, imagine your gaming computer is connected through that plug instead.. and the laptop is the second computer that runs the Hauppauge device..
Oh and by the way the TV is just optional.. you don't have to have the HD TV connected..

4⢠if you encounter an HDCP problem (that's why I ask you to read a bit about them)..
99% of the time, HDCP is not an issue while recording a game from a PC HDMI output but there is this 1% of the time that HDCP is an issue..
Most professionals remedy that by buying HDMI splitters that has the ability to override the HDCP protocol and cancel them.. or use additional professional tools like HDfury 2 or HD fury 3.. http://HDfury.com

And that's how professionals do it..
All the best.. and good luck

What are common health problems for labs?

best sound quality baby monitor
 on Graco baby monitor | Only the Best for Your Baby!
best sound quality baby monitor image






I'm adopting one tomorrow and while it's supposedly from two lab parents it could be from anyone but I'll just assume it really is a lab.

I just need a heads up on what to speak to my vet about when I take her tomorrow.



Answer
Labs are fantastic dogs but unfortunately they have been over bred and can have several health issues.
Many have a variety of skin problems and allergies. I have seen this most often in chocolate labs. Many of them tend to be on the hefty side, so monitoring food is a good habit to start. Aside from being unhealthy, if they put on too much weight too quickly, it can increase their risk of hip dysplasia.
Most dogs who have it are genetically predisposed to this but trauma and rapid growth (common in large breed dogs) have been shown to increase their chances of getting this painful and debilitating disease.
Cancer can be common in the breed as well. I have seen a greater occurrence of elbow dysplasia in them as well.
They can have different types of eye problems such as progressive retinal atrophy (PRA), cataracts and retinal dysplasia.
There are other less common problems as well. I know it sounds like a lot already, right?! There is no guarantee that your pup would have any of these issues.
You could ask about mom and dad and see if they have had any of these problems. If so, then at least you can be aware that your dog may have the same disease process in the future.
It is great that you are taking her to the vet asap. After a thorough exam they will instruct you on what to do. Make sure you get her on a good quality large breed puppy food. Many of the diseases I listed above do not appear until adulthood and beyond. You can certainly ask the vet about the occurrence of these and if there is anything you need to be concerned about.
Best of luck with your sweet baby! Thanks for adopting.

Do I need a router to go with my cable modem for a wireless connection to my desktop?




JD


I am using a NetGear WiFi adapter on my desktop (budget build) with the Time Warner supplied wireless modem, and it works well, but I no longer want to pay the lease fee. I am reading good things about the Motorola SB6141 modem. Can I purchase just that modem to use with my wifi adapter, or must I get a router too?

I am open to getting the modem/router combo if I must or even a separate router and modem. What are some of the pros and cons? I am on a relatively slow connection: 3 megs from Time Warner, and I am relatively happy with it. Could a new modem improve my wifi connection (although that is secondary to saving money)? As long as I don't go backwards in performance I am happy.

Thanks--John



Answer
Yes, the SB6141 does not have wireless routing functionality.

Two types of Internet devices are commonly sold.

1. Combination modem / routers, often called gateways.

2. Stand alone routers which can be connected to a stand alone modem.

You'll either have to buy a cable gateway or purchase a standalone cable modem such as the SB6141 that can be connected to a standalone wireless router.

The second option gives you more versatility. Router speeds and features change much more frequently than cable modems do. If you have separate units you can upgrade one if you like.

I would recommend the Motorola Surfboard line.

GATEWAY:
Motorola SBG6580 Gateway (Combo Modem/Router) http://www.amazon.com/gp/product/B007GZ2QKO/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B007GZ2QKO&linkCode=as2&tag=excharge-20

CABLE MODEM:
Motorola SB6141 Cable Modem (Modem Only) http://www.amazon.com/gp/product/B007IMPMW4/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B007IMPMW4&linkCode=as2&tag=excharge-20

I have Cox Cable 50 Mbps Internet and have had good luck with a DOCSIS 3.0 Motorola SB6120. It is just a older model of the SB6141. Here is a review I wrote a few years ago when I bought it. http://isp1.us/reviews/motorola-sb6120-surfboard/

If you go this route, there are many WiFi routers to choose from.

It pretty much comes down to what features you want and how much you want to spend.

As far as the brand goes, the brand is not as important as the model. Some manufacturers release a good model but the next is crap. I would look at the Amazon reviews of models that interest you. Even if you don't buy from Amazon the reviews will tell you a lot about which models to avoid. Look for at least 15 or more reviews with a 4 star or better rating. Read a few and see if they sound like the particular model will work for your application.

For under $50, this Medialink is the most popular and highly reviewed model. http://www.amazon.com/gp/product/B00A3YN0Z0/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00A3YN0Z0&linkCode=as2&tag=excharge-20

As far as performance goes,

No router or connection type will change your 3 Mbps Internet speed. This connection bandwidth is shared by your entire home network via your router.

For example, If you have a 3 Mbps Internet plan and one user is utilizing 2.5 Mbps of the bandwidth to stream a Netflix movie that only leaves 0.5 Mbps for all of the rest of the users on the network.

Super fast wireless routers and connections permit fast transfer of files between devices connected to your home network (LAN), however Internet (WAN) speed is still limited by your ISP. The only way to improve your Internet speed is to upgrade your plan or switch to a faster ISP.

That being said,

All wireless connections will have a slower speed than a direct Ethernet connection.

Wireless signals are affected by many factors including distance, wall density, electrical interference, directional antenna range, etc.

All of these factors will affect your actual wireless range, speed and connection quality.

You should try to centrally locate your wireless router or gateway up high and away from dense walls and electrical and 2.4 GHz wireless interference such as microwave ovens, cordless phones, baby monitors, etc.

For stationary devices such as desktop computers or devices used for serious gaming or video streaming your best bet is a direct Ethernet cable connection. Ethernet is unaffected by wireless interference and will give you a rock solid, stable network connection.

If it is not feasible to run Ethernet cable the next best option would be a set of powerline network adapters http://isp1.us/reviews/netgear-xavb2101-powerline-adapter/

You plug one in by your router and one in the room where you need access and connect them to the devices with standard Ethernet patch cables. The network signals are transmitted over your existing home electrical wiring which will not be affected by wireless interference. There is still overhead in the connection but it is much more stable than WiFi.

ACTIVATION:
Most cable Internet providers use the cable modem's MAC address to activate the modem.

Every device that has a network interface has a unique MAC (Media Access Control) address. This is usually expressed in hexadecimal such as 10:25:A4:59:EF:1C

You'll have to call your cable provider with the MAC of the new modem so they can activate it on your account. The MAC address is usually printed on a sticker attached to the modem.

Good Luck...

what is the best baby monitor to buy?

best sound quality baby monitor image



RyanA


I don't care about price. We would like one with video and sound...unless the video is of poor quality.
Thanks!



Answer
Although it does not have video, the Angelcare monitor is what I used for both my children.

http://www.angelcare-monitor.com/english/hispeed/angelcare.html

It has a movement monitor that you slip under the mattress and sound monitor combined that is ULTRAsensitive. I was always scared that my babies would stop breathing during the night. I felt it was better than a video monitor since you can't sit in front of the video monitor 24/7, (and you certainly can't watch it while YOU are asleep,) but you will certainly hear the alarm on this monitor! Very reliable, gave me peace of mind and overall one of the best monitors I've ever owned.

How do I choose the best frequency for my cordless phone?




ANG


What is the difference between the frequencies?


Answer
the best a safest you can get right now is the DECT6.0....

http://www.101phones.com/browse/18b145148f9d8fa63849b02bfc08698e/DECT_6.0_phones/?link=leftmenu

What's the difference between 900 MHz, 2.4 GHz and 5.8 GHz phones?

Your average cordless phone is actually a radio transmitter/receiver that operates across various radio frequencies. The three currently used frequencies are 900 MHz, 2.4 GHz and 5.8 GHz. As you step up in frequency, you'll experience an increase in the signal clarity and the range your phone can reach from its base station. However, the actual range and sound quality of your phone can be affected by obstructions within your home and interference from other electronic devices. Here are some general guidelines for choosing one of the three frequencies:
900 MHz

Most manufacturers have begun to phase out 900 MHz phones with AT&T having phased them out completely. Phones operating on this frequency are fine for household use and reasonably priced, though the features offered with these phones are limited.
2.4 GHz

The majority of phones on the market today operate on the 2.4 GHz frequency. This higher frequency provides better performance and sound quality than 900 MHz models. With more models to choose from, you'll also find more available features, including integrated speakerphones and support for multiple handsets. One thing to keep in mind is that other electronic gadgets, from baby monitors to wireless networking gear, increasingly use the 2.4 GHz band and may cause interference. If you use these items in your home, consider purchasing a 5.8 GHz phone.
5.8 GHz

5.8 GHz phones offer the latest in cordless telephone technology with the best clarity, range and possibly security. The biggest advantage to a 5.8 GHz phone is that its frequency band is less trafficked than the 2.4 GHz band, resulting in less interference. The chips that generate the 5.8 GHz signal are more expensive to manufacture, so expect to pay a bit more.
Analog versus digital

You can find both analog and digital models within all three of the main frequencies (900 MHz, 2.4 GHz and 5.8 GHz).
Analog

Analog technology applies to a system of recording or transmitting sound. In an analog system, the changing energy in the sound is converted to energy variations in another medium, for example, magnetism in a tape.

Analog cordless phones are the most affordable and available option. You will experience adequate range and good voice quality. Drawbacks include poor security (anyone with a radio scanner will be able to listen in) and static when you move too far away from the base station.
Digital

Digital technology is also system of recording or transmitting sound. In digital systems, the changing energy in the sound is continually measured.

A friend and I are contemplating on making a small recording studio?

best sound quality baby monitor image



stephhxraw


in her closet. Its not that big and the only instrument we use is a guitar. What can we do to go the ball rolling, as in what equipment should we buy to record and make our sounds better and where can we get the cheapest prices.

Any ideas?



Answer
Since you are just starting out, you might want to start by trying to record using Audacity http://audacity.sourceforge.net/ - Audacity is FREE down-loadable software that use to record record music on your computer. You will need to have at least one and maybe two microphones. I would suggest that you might start out with this microphone. http://www.guitarcenter.com/Nady-SP-5-Dynamic-Cardioid-Neodymium-Mic-770707-i1127199.gc - and get this wind screen for it - http://www.guitarcenter.com/Heil-Sound-Windscreen-for-the-Handi-Mic-Microphone-271334-i1423824.gc - You will also need to have microphone cable for the mic and an adapter so that the microphone will connect to your computer. This you can do for very little money and see how it works. If you can afford to invest more, you might consider buying a Pro Tools Recording Studio - http://www.walmart.com/ip/M-Audio-Pro-Tools-Recording-Studio/14123456?wmlspartner=GPA&sourceid=44444444440521189243 - The software that comes with this product is better quality than the FREE software you can download. Pro Tools also comes with the M-Audio USB interface to your computer which has a built in music quality sound card so, the quality of the sound you get when you record will be much better. You can still use the same microphone to start. Eventually you may want to purchase a better microphone and mic stands and a good set of speakers to listen to your music. http://www.guitarcenter.com/M-Audio-M-Audio-Studio-Pro-3-Monitor---MXL-990-991-Mic-Package-888907-i1471849.gc

That's really all you need to get started. I'm a songwriter and I play guitar, bass and keyboard and I write and record all of my own music using Pro Tools LE a more advanced system like this one - http://www.guitarcenter.com/Digidesign-Pro-Tools-Mbox-2-Factory-Package-773407-i1177447.gc

With my system, I can record broadcast quality music that I can write out to a CD or MP3 and I can actually get local radio stations to play my music and even sell the music on iTunes or Amazon.com or CD Baby. You will be able to create CDs and MP3s with either of those less expensive systems too. But, the quality of the sound will not be broadcast quality. But, you will be able to learn how to use the recording software and perhaps write some of your own music and when you're ready later on, perhaps you will want to purchase a more expensive Pro Tools LE system.

Sub-woofer is making a horrible noise when no media is playing?




JD


I have never had any problems with this subwoofer before. I recently moved houses and setup my system there. Everything seemed to be working beautifully until I woke up in the middle of the night to horrible feedback coming from the subwoofer. I immediately turned the power off and it stopped. So, I tried to switch the subwoofer to "Auto" mode which kind of puts the speaker in a sleep mode until it is being used. This also did not solve the problem. When music is played on subwoofer, it sounds great, but once it ends, after a while, a feedback "beat" is heard and repeated over and over. Any suggestions? This wasn't happening before the move.


Answer
Hmmm, it could be many things... I have a JBL speaker system with a powered sub and I had a similar type of feedback humm, but I discovered it had to do with the auto sleep mode. Oddly enough (like you) this only happened to me after moving into a new home, go figure! So aside from some trial and error with the power save feature of the subwoofer, it's time to dig deeper.

Do you get normal results when you run a test-tone test, if your head unit has this feature? First, if you don't own a second one, see if you can borrow another subwoofer and swap it out temporarily. Try to rule out an issue with the speaker itself, if another sub does the same, you have an issue with your head unit or cabling or power. Are you using a halfway decent power distribution system or power strip, like a monster power strip with good noise filtering? In the new house, where you set up your system, are there any sources of interference nearby like from utilities or appliances or computers? Are you using a good quality cable to conect the sub to the head unit? I realize it worked fine before, but it could be a cabling issue if there's an external electromagnetic interference problem near the new home that didn't exist at the old home, like from nearby communications equipment, alarm systems, wireless networks, cordless phones, baby monitors, wireless CCTV systems, etc.

Or it could be dirty power for these same types of reasons, so be sure to use a good power strip/filter. Expect to spend a few hundred dollars on a good one. Myself, I use the Monster Power HTS 3600. And make sure the outlets where you have everything plugged in is properly grounded. Use a tester or have someone who knows home electrical confirm it for you. Ideally, this will also be a dedicated 15 or 20 amp outlet with nothing else on it like lighting, etc.
