Wi-Fi video surveillance cameras. How to fix interference

Today the leading place on the market is occupied by wireless Wi-Fi surveillance cameras, due to the absence of limits of signal transmission distance and their easy installation. 

However, wireless cameras sometimes suffer from interference. In this article, we will discuss 3 ways to solve the problem. 

Causes of interference

According to our statistics, we can distinguish 3 main causes of video surveillance interference: 

  • physical barriers. For example, the Internet signal is interfered with by a thick wall that stands between the router and the surveillance camera;
  • frequency barrier;
  • limitation of the distance available for Wi-Fi.

Useful tips for eliminating interference

Before installing a remote video monitoring system, you need to provide the facility with a strong and stable Wi-Fi signal. Otherwise, the whole surveillance system project and the purchase will be a pointless waste of time and money. 

Additionally, it is necessary to make sure that the walls pass the Internet signal, or to install several access points, so that Wi-Fi signal will be sufficient for all devices. 

But how to remove video surveillance interference already after the installation of the system? There are 3 options. 

Channel selection

Extremely often interference occurs if the Wi-Fi signal is shared between the video surveillance and other devices. To avoid overloading the network range, connect the monitoring to separate access points. 

Physical barriers

The first thing we recommend when interference occurs is to check for barriers that can interfere with the Internet signal. For example, a window easily lets Wi-Fi through, but a mirror reflects it and concrete does not. 

The way out is simple – move the router to another location. 

Wi-Fi Range Extender

Lack of Wi-Fi range is a frequent burden of large facilities. Interference in this case is caused by the distance of cameras from the router. If this distance is reduced, the signal quality will normalize. 

There is another option. You can use an extender for the range. It will strengthen the signal and increase the coverage area. 


Video interference is a frequent but not critical problem of monitoring systems. It can be solved by manipulating the access point and buying high-quality Wi-Fi cameras
