I cut this device a lot a slack in terms of criticism because it was so inexpensive (under $40). It works as described and, with a little tedious fine tuning, it delivers a pretty clear picture.
But, it could be a lot better. The camera lens zoom and focus is pre-set and not adjustable. The only way to change the zoom is to physically move the camer back or forth. This makes finding a place to hide the camera much more difficult and challanging. The mounting bracket also adds to the challenge--it doubles the height of the unit, and is intended to be mounted with the included, tiny wood wood screws. Using the the knob on the receiver to fine tune the reception from the transmitter is what migraines are made of--keep the Tylenol handy. It's similar to trying to fine tune the dial on an am clock radio with week reception. When used with a Slingbox this camera makes a pretty neat nanny cam--the live feed can be viewed from any web browser or from a smart phone (e.g. iphone, blackberry) and can be recorded to PC if desired.
