Byte 5 and byte 6 are ransom value from 0x00 to 0xff.

Note:
This protocol is the same as PELCO-D, which is used to control speed dome. So, if you use
PELCO-D to control speed dome by a keyboard, you can also use the keyboard to control the
DVR through this protocol, we can use different address to distinguish the DVR and the speed
ome.
