Our miniature color bullet camera has a built-in 3.6mm lens and advanced technology. It is the smallest of the bullet cameras included in the H.E.A.T. line offering the same high quality technology. The miniature CVC-637EX features a 470 line ultra high resolution with a 0.03 lux light sensitivity. Additional benefits of this uniquely miniature bullet include low smear level, which prevents glare, pre-set auto exposure, and turbo AGC (automatic gain control). It is also weatherproof and ideal for outdoor as well as indoor applications.
