1. The power supply is not working properly, causing the splitter to lock up. Replace the power supply.
2. Bad access to the BNC video cable causes picture jumps.
3. Due to the mis-programming, the splitter was confused and set up again.
4. The wrong playback port was used during recording, and playback was not possible.
5. The use of simplex dividers can only be recorded and cannot be played back. Duplex, half-duplex job.
Monitoring System FAQ - Matrix 1. Whether programming is correct or not.
A. When using the sub-control keyboard, the programming of the monitor assignment and authorization is correct.
B. Whether the alarm device is correctly connected when setting alarm monitoring and recording. Whether the programming is reasonable (data conflicts with related devices).
C. Connect an external controlled device. Such as fastball, jiemaqi, alarm equipment, pay attention to the data port provided by the manual. Connect and program correctly.
2. Matrix failure
a. No display at power on, please check the fuse.
B. There is no display on the matrix box with more than 32 channels. Check whether the board self-checks whether the light-emitting diodes work properly. If it is not normal, reinsert the board.
C. When there is no output on a certain path, the normal screen of one path can be replaced to check whether it is a matrix problem or other problem.
D. If the control fails, check whether the control port is connected to the control port. Check whether the controlled device is coded. Try replacing the other port.
Monitoring System FAQ - Camera 1. No image output
a. Check if the power supply is connected and the power supply voltage is sufficient.
B. BNC connector or video cable is not in poor contact.
C. Is the lens aperture open?
D. Whether the video or DC driven auto iris lens control wire is connected.
2. Bad image quality
a. Whether the lens is fingerprinted or dirty.
B. Is the aperture adjusted?
C. Poor contact of the video cable.
D. There is no problem with the electronic shutter or white balance settings.
E. Is the transmission distance too far?
F. Voltage is normal.
G. Is there a source of interference nearby?
H. When installing in an elevator, ensure that the elevator is insulated from interference.
i. Is the CS interface connected?
