what's the best of the best babyphone / baby intercom / baby monitor thingy ?

Q. what's the best of the best babyphone / baby intercom / baby monitor thingy ? I've heard that I need to buy something with DECT and that there are also systems that monitor the baby's breathing etc... what's the top of the line system ?

A. I was also looking for a good baby monitor, and my husband and I wanted a combined video/audio one.

After much researching around and reading lots of reviews, we're going to get the:
Swann SW233-WDM VBM-330 Digital Video Baby Monitor
It costs about AUD$260.

These were our criteria for selection:
Audio - good microphone
Color video and reasonable screen size
No interference or use of multiple channels
Night vision (at least a few meters)
Thermometer a plus
Multiroom monitoring if possible
Portable receivers
Transmitter - non-battery powered
Motion sensor for stop of movement
Underwriters Labs mark for safety
Intercom
No LED flahes on camera
No Auto-mute

The Swann model does not necessarily fulfil all the criteria, but the most important ones it does fulfill, and it fulfills the most of our criteria.

Hope that helps! P.S. Swann is very good in surveillance technology.


Need a surveillance kit to put in car and catch someone keying it.?
Q. My car recently got keyed and I don't know what to do. I think it's going to happen again and want to catch the culprit. Can anyone give me ideas. It happens at my work in a public parking lot. I need some type of motion detected Video Recording Kit or Continous record that doesn't drain battery. Must be able to see out of all 4 sides of car. I need help, please!

A. That kind of equipment is complex and expensive; are there security cams at work you can park near? Look at the X-10 website for any kind of "budget" portable video surveillance equipment. "Swann" is another company . The images may not be too sharp, but if you are familiar enough with people, maybe you'll make them out enough. Maybe the "baby monitor" type will do what you want. To record the activity will take more equipment. You might need a couple of them and have the receivers in range all the time.

Talk to your boss or Human resources dept about this. Maybe they can help you.


Is there anyway to boost my reception in my basement?
Q. I get decent signal on the main floor and when i go in the basement my signal sucks. I have Verizon

A. Well here is some information that tells you what interferes with wireless signal:

Sources of interference for wireless devices and networks

The farther away the interference source, the less likely it is to cause an issue. The following items can cause interference with wireless communication:

* Microwave ovens: Placing your computer, Bluetooth wireless device, or AirPort base station near a microwave oven that is in use may cause interference.
* Direct Satellite Service (DSS) RF leakage: The coax cable that comes with certain types of satellite dishes may cause interference. Obtain newer cables if you suspect RF leakage.
* Certain electrical devices such as power lines, electrical railroad tracks, and power stations.
* 2.4 GHz or 5 GHz phones: A cordless telephone that operates in this range may cause interference with wireless devices or networks when used.
* Metal objects: If possible, move metal objects or change the placement of the computer, wireless device or wireless access point so the path between your computer and the wireless device or wireless access point is free from metal objects that may cause interference.
* Video senders (transmitters/receivers) that operate in the 2.4 GHz or 5 GHz bandwidth.
* Wireless speakers that operate in the 2.4 GHz or 5 GHz bandwidth.
* Certain external monitors and LCD displays: Certain displays may emit harmonic interference, especially in the 2.4GHz bandwidth between channels 11 and 14. This interference may be at its worst if you have a portable computer with the lid closed and an external monitor connected to it. Try changing your access point to use 5 Ghz or a lower 2.4 GHz channel.
* Any other "wireless" devices that operate in the 2.4 GHz or 5 GHz bandwidth (microwaves, cameras, baby monitors, and so on).

Note: Some devices may not overtly state that they operate in the 2.4 GHz or 5 GHz bandwidth. The operations manual should indicate the frequencies the device uses to operate. These may be referred to as "Dual Band" or "Wireless" devices.

Effect of home and office elements on wireless communication
Where you are located and what materials you are surrounded by can affect your wireless networking performance or Bluetooth wireless device. The table below shows common elements and their potential for interference.
Type of Barrier Interference Potential
Wood Low Interference
Plaster Low Interference
Synthetic material Low Interference
Glass Low Interference
Water Medium Interference
Bricks Medium Interference
Marble Medium Interference
Paper rolls High Interference
Concrete High Interference
Bulletproof glass High Interference
Metal Very high Interference

I would say your problem is Concrete because of the bricks, which are almost the hardest next to metal and bulletproof glass... But if you can get a wireless access point and get it at the entrance of the basement, it will take the signal from your router and extend it into your basement. You can take these WAPoints and move them around to see where you get the best signal in your basement with where the access point extends the signal too. I hope this helps. Also some of the other items listed above can cause inteference but I would suspect the concrete and start there. There not too expensive and you can have more than one.
