Image "pulsing" from all 5 of my Amcrest cams

[simtimpson]

I have 5 Amcrest IP cams. 2x 2MP PTZ Wi-Fi, 1 2MP dome POE, and 2x 4MP outdoor POEs. They all do this image clarity "pulsing" every 3 seconds and is very annoying. This is unrelated to an NVR as I'm accessing them direct through browsers and iOS apps (multiple, including amcrest view). It's present in all viewing and is coming from the cameras. Amcrest needs to fix this quality issue. It's almost like the cams are trying to refocus every 3 seconds. Is very slight image shift, but is constant, no matter what, and very annoying. I want a constant and clear picture, not something that pulses. It's also not the network as these are all connected to different access points, and only the 2x Wi-Fi cams are not directly connected.

I also have 1 PTZ Foscam 2 MP cam that doesn’t do any of the “pulsing” the Amcrest do. The Foscam image is 100% stable. Any fixes, Amcrest?

Hello simtimpson ,

Could you try the following workaround and see if this helps?

Go to setup > Video > Configuration > BLC mode and from the camera web interface and change the mode to HLC and set the value to 50.
