AnalogHD Cameras

AnalogHD cameras will only function when connected to an AnalogHD DVR.

If you are upgrading from a standard Analog system, you will be able to use the existing BNC power/video cable but you must to replace both the recorder and the cameras with AnalogHD technology equipment.


When installing your camera, it is important to select a proper site not only for field of view, but for other considerations as well:

Distance from viewing/recording device. The further the camera is from the DVR or monitor, the higher the chances of signal degradation. Typical 75Ω Video Cable provides acceptable signal at distances up to 200’ (60m). At greater distances, UL-Listed shielded RG59 should be used. The camera’s power supply should be located as near to the camera as possible when the distance exceeds 200’ as the power level will drop over extended distances resulting in a decrease in video quality.

Do not place near high voltage wires or other sources of electrical interference. Electrical interference will degrade the quality of the signal. Place camera out of reach to avoid damage.

Avoid direct exposure to weather. You should not place the camera where rain or snow will hit the lens directly nor should the camera be placed so that the sun or bright light shines directly into the lens. Your camera is weatherproof, but it will not work when submerged in water. Ensure that all power and video connections are not directly exposed to water and are protected from the elements.

Indoor cameras should not be used outdoors. Even if they are in a sheltered location, they can still suffer damage due to humidity, dust and other environmental factors.

Mounting surface The mounting surface must be sturdy and able to hold at least five times the camera’s total weight. Legal Considerations Always check state and local laws before installing cameras. (2011 NEC 820.44)

Do not place camera behind a window. If there is a light source behind the camera, it can cause a reflection in the window that will obscure events on the other side of the glass. Likewise, the camera’s infrared LEDs will reflect off the glass and shine into the lens, thus degrading the image.

Light levels should be approximately the same between camera and target area. A camera in a brightly-lit area looking into a shaded area, or vice versa, may produce inadequate results.

The above are guidelines and the optimal location for your camera will depend on your unique circumstances. As a general rule, the locations highlighted in Green in the picture to the right indicate the best locations to mount your camera. Both locations are sheltered from rain or snow and offer good sight lines to allow your camera to monitor a wide area. Because your camera is weatherproof, it requires less protection than weather-resistant cameras and it can be placed in more exposed locations if needed. Outdoor cameras are designed to operate between -20°F to 140°F (-28°C to 60°) with a relative humidity of up to 95%) and consider wind chill and other environmental factors when selecting your location.

adapter into an outlet at this time.



IMPORTANT! When connecting the power and video cable between the camera and the DVR, the “male” power end (red plug) connects to the matching power lead on the camera.

STEP 2 For multi-camera packs, connect the power connector on the other end of the

cable to the power splitter.

For single camera packages, connect the power lead into the power adapter itself. In this case, you can skip to Step 4.

WARNING! If you have a multi-

camera package, the included power adapter is designed to

provide enough voltage to operate multiple cameras. Connecting a single camera to the adapter can cause the optical chipset of that camera to burn out and become useless.


Connect the BNC connector on the other end of the power and video cable to a Video In port on the back of the DVR.













Repeat Steps 1 through 4 for all cameras before continuing.




Plug the power adapter into a surge

*When selecting a surge protector, it is STRONGLY recommended to use one that is UL-1449 rated, for a clamping voltage of 330 or lower, a Joule rating of at least 400 and a response time of 10 nanoseconds or less.
