Hvb Ultra Small Mini Video Camera, Wireless spy Camera  

An ideal surveillance camera for most situations.

Its compact shape allows easy fit into tight spaces;

the slim body of the camera lets you set it up even

in those cramped corners without any hassle.

Wireless cameras are also available in covert versiones. These are best for quick, temporary installations.
For permanent installations, I recommend hardwired cameras.
