DV950A - The world's smallest DVR
Bigger isn't always better. Compact size can be critical, but it's useless without a top-notch performance. Some little DVR's claim to be the world's smallest. Not only are they larger than this unit, they don't deliver nearly as good an image. What you record onto this next-generation DVR you can play back on a full-sized screen with no loss of quality. This supports up to a 4 GB mini SD card for up to 14 hours of high-resolution video, more than three times as much at lower resolution. And you can easily tuck it away in a pocket.
Most DVR's in the market can record video at320X480 @15 FPS, one other model can do as much as 640X480 @ 15 to 18 FPS. Some claim that you can upgrade the firmware and get better resolution (that's simply not possible as resolution cannot increase without degradation of the image, it's like blowing a balloon with writing on it, sure you can make it bigger but past some point the image will degrade).
Resolution simply put is the SIZE of the image of 640 pixels horizontal by 480 pixels vertical, which is perfect as these just happen to be your PC's VGA standards.
