ZZ ---- the current ID
Example:
Send: 56 FF 90 01 21
Return: 76 FF 90 02 21 04
Notes: when setting the ID for RS485 cameras, if the camera ID is unknown, there are two methods
to find out, one is from the “MEID_Num” outputs when the camera gets powered up, another is to
issue “get camera ID” command, 0xff from command is the broadcasting ID, which is only valid for
checking/getting ID.
27. ABNORMAL RETURN: 65 72 72 6F 72
(65 72 72 6F 72 means “error” in hex format)
28. INITIAL OPERATION PROCESS:
（
1
）
power up with the matching voltage, delay 3.5s
（
2
）
camera outputs: “MEID_Num:” + camera ID, and “Init end”
（
3
）
set image resolution command (optional, if it’s already set once and no need to change, then
skip this step)
（
4
）
set area cropping command (optional, doesn’t get saved after reboot, set once only after power-

for the next image, repeat from step (7)
29. CONTINUOUS CAPTURING IN MOTION DETECTION PROCESS:
（
1
）
set motion detection continuous capturing command, such as: 56 00 88 04 05 0A 00 64
（
2
）
set the sensitivity in motion detection command, such as 56 00 31 05 01 01 1A 6E 03
