Wireless camera signal interference can be caused by multiple factors.
Understanding Wireless Range
The signal range also depends on whether there are competing signals using the same frequency as the camera.
If you are finding your wireless signal is dropping, or your connection is slow, check for wireless signal interference.
To reduce wireless signal interference:
Relocate the wireless cameras and their receivers a minimum of 10ft (3m) from the router and other wireless devices. You may need to move the camera and DVR / NVR to a different room and use a longer Ethernet cable.
Turn off one or two of the cameras or receivers and check if the connection quality increases. If so, consider using a combination of wired and wireless cameras to minimize signal interference.
Wireless cameras transmit signals on a 2.4GHz bandwidth. If you have a dual band router, reduce traffic on the 2.4GHz band by connecting your smartphones, tablets, and computers to the 5GHz band.
If you have a single band router, contact your Internet service provider (ISP) to switch to a dual band router.
Ensure that you do not have more than 2 wireless range extenders per household.
We recommend a maximum of four wireless cameras per household. Additional cameras may cause issues with signal interference. If more cameras are needed, consider using a combination of wired and wireless cameras.
