The 2.4 GHz Wireless Security Color Video Camera claims to be a professional grade surveillance which fulfills all your spy tendencies and is ideal to keep a check on all the activities around you! It claims to capture ultra clear images and one can use 4 cameras per wireless receiver (additional cost for each camera) to view 4 different locations while sitting at your desk or even in front of your television. Just plug the receiver into your PC desktop or television and watch all the action.

I like the fact that each camera has a built-in near-infrared setting which ensures better viewing even in low light conditions. Order it online here and the surveillance camera is available for around 100 bucks.
