Wireless Cameras and Interference

The wireless camera transmits its images on a radio frequency of 2.4 GHz. Although above
the range of the average radio, some devices (e.g., wireless computer networks, cordless
phones, baby monitors, car alarms, and Bluetooth) transmit signals at or around this
frequency. Other devices (e.g., microwaves) create radio "noise" at this frequency as well.
Placing your wireless cameras or DVR near these devices, or having any of these devices
in between your cameras and receiver, can cause interference and affect picture quality.
This happens because the signals are so similar, that they get mixed up with one another,
and your receiver has trouble figuring out which is which.
To reduce interference, try the following:
Disconnect all other wireless devices, one at a time, to find out which one is causing

the problem, and adjust your setup accordingly.
Move the camera to a different location, or change the orientation of the antenna on

the camera and the wireless DVR.
Adjust or aim the DVR receiver antenna.

Limit the number of walls and floors between the camera and DVR.

Move the camera and/or DVR away from dense materials, such as concrete or metal,

which impedes the wireless signal.
If you are still having problems with your analog wireless system, consider changing to a
wired camera or to a digital wireless system. These units are not subject to interference in
the same way as analog wireless systems.
