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 oers 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.

Precautions

1.3. PART IDENTIFICATION

Shell screw
(Countersunk M4x6 mm)

NOTE: The sensor must always be mounted on

a steady foundation, such as a wall or a
pole that is well secured to minimize risk of
misalignment due to vibrations.

NOTE: The sensor has a maximum detection range

of up to 1640.42ft (500m). Recommended
range for demanding applications is

984.25ft (300m) to ensure detection of
small objects such as people, even in dicult
weather conditions.

1.4. PREPARING TO MOUNT THE LASER SENSOR

1. Do not stare directly into the red alignment laser. Do not leave the red alignment laser turned on after installation process
is complete.

2. Use wall brackets and tripod with compatible mounting only.

3. Install the product on a solid surface.

4. Install the product so that the detection line is not obscured by interference from tall grass or tree branches waving in
the wind.

5. For perimeter protection, the unit should be placed at an optional detection height and parallel to ground.

6. Do not install or leave the product in a location exposed to heat, vibration or impact.

7. The SiteWatch™ laser sensor is compatible with a number of conventional wall brackets used for surveillance cameras, all
standard accessories, such as pole mounts, corner mounts etc., can be used.

8. When using the product for mobile applications, the threaded UNC 5/8” - 11 hole is compatible with most surveyor
tripods.

9. Using the mounting accessory, mark and drill all necessary holes in the mounting surface.

1.5. CABLING THE LASER SENSOR

The SiteWatch™ laser sensor is powered with Po E and all communication is made with TCP/IP. For applications that require cables
over 328ft (100m) between unit location and nearest switch or router it is necessary to use network extenders or fiber optics.

1. Remove the shell and service lid.

2. Insert the network cable without a connector through the cable gland. Crimp RJ45 connector to the cable then plug into
the RJ45 jack.

Power input

Power over Ethernet (48V DC) or 12V DC

Power consumption

4W, class 2

3. Tighten the cable gland to secure the cable and seal the casing.

4. If the relay is desired to be used, replace the plug on the
backside with supplied cable gland.

5. Connect the signal cable to the terminals. Choose
connection for desired function, normally open (N/O)
or normally closed (N/C).

6. Replace the service lid and shell.

Installation

2. INSTALLATION AND DETECTION METHODS

2.1. Detection methods

With fully adaptable alarm zones, the sensor has many detection methods customizable to any application. Below are
three typical applications.

2.1.1. Perimeter detection

The sensor is used to detect all objects crossing the virtual fence. Zones can be created along the line of sight to
permit dierent actions based on object location. For these types of applications, the sensor should be placed at the
optimal detection height and aligned with the ground.

2.1.2. Spot surveillance

Detection is only desired in a specific area (a part of a road, an entrance to a house or along a wall). In these
applications, the sensor can be located anywhere with a clear line of sight to the detection area.

2.1.3. Change detection

The sensor is used to detect if an object moves. In these applications, the sensor can be located anywhere with a clear
line of sight to the object.
