Choosing a location for your Camera

With a vari-focal camera, you have some flexibility on
where the camera can be mounted. Some things to
consider when choosing a location -

1) What you want to monitor and where you’ll get the

best view of it.

2) How you’re going to connect the camera to your

DVR; remember that cables and connections should
be kept out of the weather.

3) It’s recommended to mount your cameras at an

elevated position to keep out of harm’s way.

4) Make sure your camera has minimal sky in it as

the light in daylight can make the foreground of the
image darker.

5) Think about the most likely way a potential offender

may approach your home.

6) The camera’s casing is resistant to water and

tampering. However, the cable and connector are
vulnerable and require protection.

7) Even though the camera is weather and water-

resistant, prolonged exposure to adverse weather
conditions such as sunlight or excessive moisture,
may eventually damage the internal components of
the camera and adversely affect its performance.

8) When running your cable, try to avoid bending it at

sharp angles.

9) Don’t put your cable near live electrical wiring. AC

electricity generates radio “noise” which can interfere
with the signal from your camera.

10) A vari-focal camera allows you to adjust between

its top and bottom limits on its view angle. This means
that you have the ability to manually set both the view
angle and level of zoom. Have a scenario where you
need to zoom in on a gate or other access point?
Use the 12mm setting (27° and about 4x zoom).
Need a wide angle view? Go with 2.8mm (65°). Need
something in between? Try 6mm (43°) or 9mm (30°).
