Guide to improving FLIR FX WiFi performance

Follow the steps in this guide to get the best possible WiFi range and performance out of your FX camera.

Router and camera placement

The most important factor affecting the performance of your FLIR FX camera is the placement of the router and camera. Make sure to install your router in an open space and as high off the floor as possible. Adjusting the antennas on your router can also make a difference in terms of which areas of your home get the best coverage.

The closer the camera is installed to the router, the better the WiFi performance will be. However, obstructions between the camera and router are often more of a factor than distance. Minimize the number of walls or other objects the signal must pass through. In the drawing below, the camera placed further away from the router can perform just as well as the camera indoors since there is a line-of-sight connection.

Also keep in mind that materials such as metal, brick, concrete will significantly reduce the signal strength. Plants and trees can contain water in the leaves, which can also reduce signal strength.

When Signal Passes through Signal Strength Lost
Plaster & Wood
10 - 30%
Brick 30 - 50%
Concrete Cinder Blocks 50 - 70%
Metal & Metal Cladding 70 - 100%

Other wireless devices may also impact performance. It is recommended to have your router and camera as far as possible away from cordless phones, microwaves, and any other wireless devices.

If it is not possible to move your router to hit that spot where you absolutely must keep an eye on, you can also consider purchasing a WiFi extender. A WiFi extender will connect to your existing WiFi network and repeat the signal from a second location.

Testing WiFi signal strength

Your smarphone or tablet may have a visual indicator of the strength of your WiFi signal in the notification area. It is recommended to place the camera in an area that shows a full signal.

For an even more accurate picture of your WiFi network's performance, you can use some 3rd party apps such as Assia’s Cloudcheck or Amped Wireless’s Wi-Fi Analytics Tool.

NOTE: Check with the publisher for support on any non-FLIR mobile apps.

Testing connection speed

A slow connection may also affect the performance of your FLIR FX camera. It is recommended to have an upload speed of at least 1Mbps or higher per camera. You can check with your Internet Service Provider or use 3rd party websites such as to check your connection speed.
