Weird configuration changes after power problems

Severe storms knocked out power yesterday afternoon, restored today mid-morning. Everything seemed to come back up OK in Security Spy, but no access to the browser interface.

Tonight another storm came through, some sort of power surge or interruption knocked out my router, then seemed to only affect the wireless radio, eventually got it all going after a reboot except for 2 cameras. Goofed around and ultimately found that both had been set to static IPs but somehow had become reset to Onvif profile. Used a few tools to figure out what their IPs had been and that did the trick. A while later I checked on the web interface problem and found the address had changed from 192.168.1.42:8000 to 192.168.1.35:8000.As far as I can tell nothing else about my system or apps is showing any strangeness.

    Based on your description, it's difficult to know exactly what went wrong, but the possibilities are:

    1. The devices that changed weren't actually set to static IP addresses, so the change was simply caused by being power cycled.
    2. IP addresses were assigned by DHCP reservations in the router, and a power surge corrupted router settings. If you noticed any other settings changes in the router then that points to this possibility.
    3. IP addresses were assigned in cameras' own settings, and the power surge corrupted these.

    Now that everything is back to normal, it's worth doing a quick audit of all devices and IP addresses, and setting up a comprehensive list of DHCP reservations for each device in the router.

    It's unlikely that SecuritySpy's settings were corrupted - if the surge affected the Mac, you would likely see wider problems on the Mac, not SecuritySpy-specific.
