IX-MV / IX-MV7-* Unresponsive or Frozen Screen, or Power Cycling

Estimated reading time: 1 min

Summary

There are three scenarios. (1) A programmed and functioning IX-MV or IX-MV7-* has its screen suddenly freeze or become unnavigable which is resolved with a manual power cycle. (2) An IX-MV or IX-MV7-* freezes immediately when deployed on the network, before any functionality can be tested. This is not often the case if the station is removed from the network and placed in a bench test scenario. (3) An IX-MV or IX-MV7-* appears to constantly power cycling itself without being prompted. 

 

Cause

Possible causes for these three scenarios. (1) This uncommon issue can happen with extreme or continued improper use of the station and its primary functions. For example, the user pressing the door release button repeatedly to release the door can cause the screen to freeze. Reviewing how to properly use the product can typically resolve these issues. Using this example, only pressing the door release button a single time to unlock the door can help avoid freezing the screen.

 

For scenario (2) and (3) both can be caused of improper network settings, or external interference by other network devices. For example, an NTP server is set for a station but that server is unreachable. The station may power cycle itself to try and refresh the connection attempt. Other similar issues include IP conflicts, unidentified or unwanted requests from VMS servers, and others.

 

Solution

To better troubleshoot these scenarios, the station’s log can be downloaded for review. This log will show basic use, functions, and errors. Some errors, like an unreachable NTP or DNS server, will be clearly displayed in the text. Other errors are more generic, for example “Communication Error”, which commonly means the station is unable to establish a network connection to the device of which it is trying to communicate. “Watchdog Error” is commonly seen in situations where an unwanted and unknown IP camera, NVR, or VMS server is trying to interact with the station. A scan of the network by that product looking for ONVIF devices can then send a request to the station. If this error is found in the logs, the source of that request must either be configured not to communicate to the station, or the station needs to be removed from the environment, for example, places on its own VLAN.
