Please check if IR cut filter work.

On IR cut filter switching, you will be able to hear a clicking sound from a camera.

There are two ways to hear the sound of IR cut filter switching, one is to reboot a camera and the other is to switch the filter manually on a setup page of a camera.

As a camera boots up, it switches IR cut filter and you can hear a clicking sound.

Or, go to Remote Setup page of a camera and change IR Cut Filter option to “Daytime Mode” so that the camera can switch the filter manually.

If you do not hear a clicking sound from a camera when you expect to hear the sound, it would be likely to be a hardware issue, please contact the distributor from who you bought the camera or IDIS Technical Support team.
