ZZ ---- 1byte setting results: 0x00 setting succeed, 0x0E—already in power save mode
Notes:
After issuing the command, the delay for response takes about 800ms, and it can save around 50%
power. Once the camera is set in power save mode, the host must issue “exit power save mode” first
to wake up the camera, as when the camera is still in power save mode, it only responds to check
version/reset/set power save commands, and outputs “76 00 3E 00 0E” for any other command. If the
motion detection is enabled, the host must disable the motion detection before setting the camera
into power save mode.
