Surveillance alarm troubleshooting
1. LAN devices can’t see video online and can’t read network parameters.
Solution: The device IP and computer IP are not in the same network segment or under the same level router. Please check the routing settings.
2. Intranet devices are sometimes online and sometimes not.
Solution: a. IP conflict. There is a device (computer or other network device) with the same IP as the camera under the same router. Please modify the camera IP and make sure it does not conflict with other network devices.
b. The quality of the network cable is not good. Standard Cat-5 network cable is required especially in case of long distance transmission.
c. The production of mesh crystal head is not standard or the quality of crystal head is not good. Please remake or replace the crystal head.
d. The network cable distance is too long. It is recommended to add switch repeater for more than 100m distance network cable.
3. The communication distance between the remote controller or door contact with the alarm panel is too short.
a. check the device installation environment. Are there metal or wireless router to interfere the wireless communication. The alarm devices should not be installed near metal door, metal partition wall or metal partition. When the door magnet and wireless module are installed in the metal door or window, the connection wire should be extended to avoid interference.
b. Low battery for the remote controller or door contact, please replace the battery.
4. Slow remote video playback
a. The computer will check the connection channel when playing the device for the first time, so there will be a slight delay when playing the device for the first time.
b. Slow network upload from the device and slow download at the computer caused playback delay. So, insufficient bandwidth is the problem and should increase the bandwidth.
c. Router setting: should turn on router UPNP
5. Voice intercom of anti-theft alarm is not available.
Solution: The audio setting of the anti-theft alarm device is incorrect. Correct it and turn on the UPNP function of the router (external network mode)
