Answer
Sounds rather bad to me.

Here are the pieces of information that turn me off:

"Camera effective pixels: 16.1 megapixels"
Too many MP. That causes needlessly much image noise in low light situations. MP are NOT a measure of image quality!

"Optical Zoom: 21x
Focal Length: f=4.5â94.5mm (25â525mm in 35mm equivalent) / (27â567mm in 35mm equivalent in video recording)"

Such excessive optical zoon is detrimental to image quality.

"Aperture: F3.1â5.8 / two-step (F3.1/F8.9(W) / F5.8/F16.7 (T))"
These maximum aperture figures are rather poor. This further excarbates any problems in low light situations or to sustain sufficient shutter speeds at extreme zoom.
Low numbers are better here.

Then again, these specs may perhaps be reasonable for a superzoom camera - but that type of camera usually sacrifices image quality for convenience. These cameras offer the worse image quality compared to other point and shoot cameras at the same price figure.

would i be able to save if...?

The newest product offered by Indianapolis-based Enjoin, LLC, provides a do-it-yourself video monitoring solution for businesses, homeowners, and parents.

Enjoin has developed Eyecopia, a feature-rich PC-based software application that works with off-the-shelf web cameras to provide a monitoring solution with video and audio recording capabilities. The application utilizes innovative motion detection technology to automatically record video events as they occur. This eliminates the need to constantly watch a video feed for activity.

The software simplifies the management of collected video events through a unique categorization system. Users are given simple, yet flexible options for reviewing, sorting and archiving these events, by removing the time-consuming data management issues typically associated with video monitoring systems.
Advanced alert features keep business owners informed while they are away.

In addition to unique categorization capabilities, the program utilizes customizable notification functions to keep the user informed at all times. Notifications can be sent in a variety of ways:

* Email messages with photo or video attachments of the motion events
* Text messages to SMS-capable devices, such as cell phones and pagers
* Secure network notification to Eyecopia Remoteâ¢, a freeware program from Enjoin

The Eyecopia Remote monitoring application runs on remote computers. It receives motion-detection event notifications and displays a live view of any Eyecopia monitoring system for which the user is an authorized contact. Eyecopia allows users to share this experience with their family and friends without fear of unwanted access. The user always has the final word over who is watching their Eyecopia system.

The combination of Eyecopia and Eyecopia Remote are perfect for office use, particularly those offices with a lobby separated from employee work areas.
Get extra assurance that homes are protected with Eyecopia.

Homeowners enjoy the peace of mind Eyecopia brings them when away from their homes. Whether at work or on vacation, Eyecopia's flexible notification schedules allow users to stay informed wherever they go. In addition, monitoring schedules allow users to set times during the day to monitor for activity. Eyecopia helps guard homes and provides alerts about meaningful activities around the home such as the delivery of an important package.
Parents find comfort knowing everyone is safe at home.

With Eyecopia's customizable alert features, parents are notified when the kids return from school, as well as other activities around the house. Parents can receive alerts via email while at work and cell phone text messages while they are on their way home in the evening. Work-at-home parents appreciate the convenience of using Eyecopia as a baby monitor.
Everyone can find a fun use for Eyecopia.

Although Eyecopia offers many security-related advantages, hobbyists have found fun uses for the application as well.
