For example, if you request a video from, say, 9:00 AM GMT+0, and the camera time is GMT+0 (matches our device's time), it is all fine. But if you were to configure time zone later to, for instance, GMT+10, the camera time will be set according to that time zone (time forwarded by 10 hours in this case). Which means that time gets forwarded with no real continuation as the camera does not understand the concept of time zones, it just uses time that we set. For continuation reasons in our device, we continue using GMT+0 in the camreq and then compensate with time zone if needed. The result of that, if we send the same request command as before (when requesting 9:00 AM video) with time zone GMT+10 set, the camera will receive video request for 7 PM (19:00) and the videos were not recorded at that time which will result in "file doesn't exist".

==Other camera related functionality==
Camera is configured if all of these conditions are met:
#'''RS232 mode is selected (DualCam)'''
#'''Camera was not configured since startup or one of the related parameters were changed (compression, framerate or OSD)'''
#'''Camera file transfer is not active'''
Active camera reconfiguration is accompanied by two consecutive camera shutter clicks.
If camera is disconnected and later reconnected, a device will detect it by periodic camera ping packet. Once camera is detected, the device will reissue the reconfiguration procedure.
