Common Questions and Answers (QA) for MDVR

Q: 3G/4G signal is intermittent and video is not smooth

A: So far, WCDMA and EVDO has good coverage (4G is desired to be improved). In case where signal is not covered in some mountainous areas or signal is weak due to local network restrictions in some suburban areas, the video may not be smooth or even cannot be viewed. In this case, it is largely affected by the local network; in addition, check if the frame rate for the sub stream is set too high. This may occur when the network condition is poor while the frame rate is high.

Q: Connection is impossible even when WiFi signal is up to -60db

A: If your WiFi is correctly set, connection is generally not a problem when signal intensity is up to -60db. If the device cannot be found within LAN, check if SSID and password are correctly set. Of course, the IP address shall be properly set; in addition, check the encryption type and authentication mode are set to requirements.
