04: How to clear the alarms?
04: Under the status of login, you can clear the alarms by pressing the “Clear” button on font panel or “Alarm Clear” key on the IR remoter,
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 hosts 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.)
02: How to connect multiple PTZ cameras, or PTZ devices?
02: 1. Please make connection in star method: Connect multiple controlling lines (RS485) in parallel connection, and set addresses properly.
2. Bus connection: Connect 485+ and 485- to the DVR’s 485+ and 485- pins, and connect the next DVR’s 485+ and 485- to the first DVR’s
485+ and 485-. You may need to add a terminal resistance. Please read the P/T unit manual.
03: I opened motion alarm and sensor alarm, but I got misinformation frequently. Why?
03: Please check and set motion detection sensitivity properly. (Motion detection is sensed motion by light intensity. In case you set it very
high sensitivity; day & night changing may trigger an alarm)
1. In case your sensing equipments are of high power consumption, to avoid damaging the alarm output module, please make relay extension
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.
