This perfectly designed outdoor color camera with 56 IR LEDs and external zoom uses superior state-of-the-art technology. With its 1/3 Sony Super HAD CCD chip set, this camera is able to produce 540 TV lines of resolution, giving you the best picture possible for your surveillance system. With the new split-glass technology, you no longer have to worry about the reflection caused by some IR cameras. The lens placement is separate from the IR LEDs. Adding this camera to your home or business couldn't be easier: You can connect the camera to your TV, VCR or DVR in a matter of seconds. This camera comes standard with a female BNC connector, so if your TV, VCR or DVR does not support BNC, you will need to purchase a cable with an adapter to make the connection possible. This perfectly designed camera gives you the ability to change the focus externally after you've completed your installation. This is made possible with the two external varifocal adjustment rings. The built-in f=4-9mm varifocal lens gives you the ability to change the magnification of a scene. The most beneficial thing about this feature is the fact that once the camera is installed, you can change your viewing distances without having to take down and apart the unit itself.
