User Manual
Introduction
The DW-DTLA500 is a laser surveillance sensor that allows the user to monitor and locate intrusions for applications 
where physical fences are not desirable, possible or where enhanced security is required. The 1640ft (500m) sensor 
works without reflectors and reacts in fractions of a second. The DW-DTLA500 SiteWatch™ sensor knows the exact 
position of an object and oers adaptive alarm settings. For example, the sensor can be set to react to cars only in a 
specific lane and alarm if an object has stopped or if a door opens, while ignoring all other activities.
1.1. SPECIFICATIONS
FIELD OF APPLICATION Outdoor surveillance and monitoring
ALARM ZONES
Up to 20 fully adaptable zones, each zone 
has individual alarm sensitivity settings 
and alarm actions.
ALARM ACTIONS
Network alarm, relay. Easy direct integration with 
IP to VMS, enabling PTZ control, automatic video 
recording and object position.
SELF AWARENESS
Adaptive digital processing algorithm 
suppresses noise from fog and snow, 
and detects challenging weather to allow 
alarms to VMS.
