This infrared bullet camera has 4-1 switchable technology meaning it is compatible with older Analog Over Coax and the New HD Over Coax Cameras (Analog, CVI, TVI and AHD). This camera can see both far and wide with a built in adjustable lens. See up to 180 foot in complete darkness with the built in infrared illumination. Very clear camera in both day and night. This camera is great if you are trying to capture objects at a distance. You can manually adjust the lens (focus and zoom) at set up to the perfect angle for your application. The 2.7mm is SUPER WIDE, and the 13.5mm covers distance. So basically this camera has multiple lenses that you can adjust. Whether you are covering a wide angle such as a room or outdoors, a register or an aisle, or if you are honing in on an object further away such as a mailbox or entry way this camera can do it all. Lastly, whether you have an older analog system or HD Cameras (CVI, TVI, AHD) this camera is compatible. You choose the technology and the camera will do the rest.
