or by clicking “Alarm Clear” in the menu using mouse. If the host DVR is locked, please login first.
05: Why I cannot control PTZ devices, e.g. speed dome?
05: 1. please check if you have connected 485 controlling line to DVR correctly. 2. Please check DVR settings, i.e. protocol, baud rate are set
the same as the PTZ device. 3. Check whether the address code of the PTZ devices and the settings of DVR host channel are consistent or not
(if can not control, can adjust forward or back one address code for testing). 4. If several DVR hos ts connect with a same PTZ, the host must
enable “System Management”-> “Serial Port Setting”-> “Serial Port Keyboard” on DVR host. (Note: The host has over 30 kinds of commonly
used protocols, please patiently test whether your PTZ or high-speed dome protocols can be used in our DVRs.)

high sensitivity; day & night changing may trigger an alarm)

connection.
2. In case you are using high frequency equipments, e.g. High frequency lights please make relay extension connection method, or alarm module
may not work properly.
