As said in a previous post, the IR led is only ON during a call. Digging a bit in https://s3.amazonaws.com/amcrest-files/Amcrest+HTTP+API+3.2017.pdf I tried the following:Do you guys know if there is any way to control or change settings for the infrared/night vision? Is there a way to have it constantly on during the night? I don't seem to find any settings for this and need help...
Response when not in a call (IR light OFF): table.Lighting.Mode=Off
Response during a call (IR light ON): table.Lighting.Mode=SmartLight
Unfortunately, the command below does not turn the IR ON.
However, during a call the command below turn off the IR for a couple a seconds, then it turns back ON automatically.
It looks like the device firmware overwrites the commands.
