People frequently ask the question, “Can wireless cameras interfere with WiFi?<\/strong><\/em>“<\/p>\n

The quick answer is, yes, wireless cameras can interfere with the WiFi, but it all depends on how your system is configured, and there are always to prevent that.<\/p>\n

Let’s take a look at how that happens and how to avoid this problem.<\/p>\n

How the security cameras interfere with the WiFi<\/h2>\n

Most wireless security camera kits <\/a>bring an NVR (Network Video Recorder) and some cameras that use the 2.4Ghz WiFi band to communicate.<\/p>\n

When the NVR <\/strong>and the WiFi cameras transmit data, it’s possible to have some interference in your local wireless router<\/a> depending on the frequency and channels it’s using to communicate with the other devices in the network.<\/p>\n

The explanation is very simple; there are a limited number of channels your router can use to receive and transmit data in the network. If your WiFi cameras<\/strong> are using the same channel or an adjacent one, they can cause interference.<\/p>\n

The picture below shows the 11 WiFi channels <\/strong>available in a WiFi router.<\/p>\n

As you can see, channels 1,2,3,4 and 5<\/strong> overlaps. This means they use a frequency with some point in common, which’s not good because there’s some interference between them.<\/p>\n

How to setup the WiFi cameras to avoid interference<\/h2>\n

You can prevent your WiFi cameras from interfering with your router by following some simple rules or using a different frequency. Let’s dig into that.<\/p>\n

Here’s how to avoid WiFi camera interference:<\/p>\n

    \n
  1. Use channels 1 for your router and channel 6 or 11 for the NVR;<\/li>\n
  2. Enable both WiFi bands (2.4 GHz and 5GHZ) in your router;<\/li>\n
  3.  Set your other devices to use the 5GHZ WiFi band.<\/li>\n<\/ol>\n

    The ideal channels to use are 1, 6, and 11<\/strong> since they are separated apart and don’t interfere with each other. You just need to plan how to use such channels.<\/p>\n

    So, it’s essential to separate the <\/span>WiFi router<\/span><\/a> and the NVR using such channels.<\/span><\/p>\n

    The best approach is to use a dual-band router<\/a> to work with the <\/strong>2.4 GHz and 5 GHz bands. You can use the 5Ghz for devices (modern laptops, mobile phones) that support such a frequency, thus avoiding interference with the NVR.<\/p>\n

    Other things to reduce wireless interference<\/h2>\n

    Be aware that Wireless interference is also caused by other devices such as your neighbor’s WiFi router, a microwave oven, a cordless phone, etc. <\/span><\/p>\n
