This four pack of PRO-735s efficiently operate with a powerful 720TV Lines of High Quality Video & Recording, far greater than average analogue recording. The 735s are fully capable of medium range night video recording with 25m of Night Vision. With a weather proofing rating of IP67 they can withstand harsh Australian temperatures and conditions. Place the camera in a position that a potential security threat will find it difficult to avoid detection. A strategy which is often effective is to monitor entrances and exits - after all, a security threat has to get in somewhere. The camera's night vision will give well exposed images if the area is dark. However, if there's a bright point source in the camera's view (a streetlight, car headlights or similar) then it might not engage night vision mode.
Install the camera where it's out of reach to prevent tampering. For example, under the eaves of a roof or high up in protected corners of a wall would be good options. The higher the camera is mounted, the harder it will be for vandals to interfere with it. Typically, the best view is obtained approximately 2 Metres to 3 Metres high, looking slightly downwards. Try to aim the camera at an area which is evenly lit, as objects or people in shadows near brightly lit objects are very hard to see. While the camera is sealed, robust and able to handle the weather, long-term exposure to direct sunlight (particularly UV) and moisture will eventually cause a degradation in performance, so if it's going to be installed outdoors, make sure it's in a sheltered spot. Also, when mounting the camera, ensure that it's not in a location where water is likely to pool or build up over time.
Connecting To The DVR: 1. Connect the camera's Power and Video cable to the extension cable's DC and BNC plugs. 2. Connect the BNC extension cable to a video input channel on the back of the DVR. 3. Connect the DC extension cable to the power adapter's DC cable and then plug the power adapter into an electrical outlet.
When running your cable, try to avoid bending it at sharp angles. Don't put your cable near live electrical wiring. AC electricity generates radio "noise" which can interfere with the signal from your camera.
