Common Error #1
“The system is active, therefore it must be recording”
On-screen display of the cameras or proper functioning of system menus is insufficient as indication that the recording system is in proper working order. Moreover - the system is capable of working regardless of the existence of a recording drive.
In most cases, recording malfunctions do not disturb the system's overall visual functionality and will not always trigger relevant system notification.
Only proactive physical testing of recorded files on each and every channel is able to confirm the system is recording content as required.
