In bright daylight, the camera showed sharp details, providing a clear image of everything in the room. The Flir FX doesn't have the same clarity in ambient daylight, but still produces excellent video. In nighttime video tests, the Flir FX was a close second behind our top performer, Belkin NetCam HD+, though its video clarity weakened beyond 10 feet. Setting up Flir FX is unusual, as it doesn't work until its batteries, one in the camera and one in its base, charge for at least 30 minutes. However, no other security camera in our review has a battery backup. We didn't like that the mobile app makes you hunt for the button to view video, which isn't as convenient as putting it on the main screen when the app opens.
