Appendix 2 Troubleshooting
1. The device fails to start normally:
(1) Network line from the device to POE module exceeds 40 meters.
(2) Network line has poor quality and materials.
(3) Crystal plug of network line isn’t connected firmly or line sequence is wrong (crystal plug shall be
remade).
2. IP address is forgotten and factory settings cannot be restored.
Please manually press Reset key for 5-10 seconds. After all LED lights of the device turn on, input
IP:192.168.1.36 to log onto the device.
3. My computer cannot find wireless AP. Why?
Solution: wireless system will connect at the maximum working rate, and specific rate will depend on
distance and environment. To obtain maximum possible connecting rate, the following links shall be
tested:
(1) Position of wireless AP
Try to adjust the position and direction of wireless AP.
(2) Wireless channel
Use other communication channels. Interference may be obviously improved.
(3) Wireless interference
Other devices may cause interference too. Turn off other devices and check whether it is improved.
Interfering devices shall be shielded or relocated.
4. Too low signal strength is due to the following reasons:
(1) Client fails to be visible for AP, because of large obstacles.
(2) Surface plate of client doesn’t align with AP; angle of pitch of AP and client is inappropriate.
(3) Client is installed on a window, which easily leads to planar interference.
