Having a surveillance camera in or around your home or business can be an enormous benefit. This outdoor color camera with external focus is the perfect bullet-style camera that easily connects to your DVR, TV or VCR, allowing you to view or record any activity around your property. With 480 TV lines of resolution and a 1/3 Sony Super HAD CCD lens, this camera puts out an amazing image. 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.External Adjustment for Focus and Zoom 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.
