What kind of Alarm triggering is supported by the DX-TL900U to generate an alarm?
a. The DX-TL900U supports two types of Alarm trigger, Motion (per input) or External via the rear terminals (grounding the normally open terminals to generate the alarm). b. Programming the RECORD SETTING enables you to specify ALARM or ALARM PLUS record settings. If a specific camera or cameras are only needed to record during an alarm then selecting ALARM (not ALARM PLUS), from the RECORD SETTING MENU is required. Also, enable the specific camera input by allocating the number of PPS (Pictures Per Second) and REC GRADE associated with that input.
