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 offers adaptive alarm settings.
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. Shell Main unit 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 difficult weather conditions.
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 different actions based on object location.
Operation Principles 3. OPERATION PRINCIPLES 3.1. Sensor placement The sensor has a maximum detection range of 1640ft (500m). The recommended range for demanding applications is 984ft (300m), to ensure detection of small objects such as humans, even in difficult weather conditions. There are two ways to create a continuous virtual fence with the sensors. 1. They can be placed 984ft (300m) apart and have an overlapping detection area as shown in figure A.
Operation Principles If it is less than 16.4ft (5m) between the objects, the sensor will cluster the objects and use a weighted averaging to calculate a virtual object position. If each object gets 50% of the laser beam, the calculated distance will be in the middle between the objects. If the first object gets 75% and the other 25%, the calculated distance will move closer to the first object. Calculated distance SiteWatch™ sensor > 16.4ft (5m) Calculated distance SiteWatch™ sensor > 16.
Combining the laser sensor with IP cameras 3.5. Combining the SiteWatch™ laser sensor with surveillance cameras The SiteWatch™ laser sensor is designed to detect objects and alarm to a VMS software such as DW Spectrum® IPVMS, or directly to an IP camera. With a dedicated detector, fewer cameras can be used since they can be programmed to the exact location of an intrusion. The number of cameras required depends on camera type.
Combining the laser sensor with IP cameras 4. INSTALLATION AND ANGLE ADJUSTMENT 4.1. Alignment The final alignment adjustment of the sensor is made with the adjustment screws on the side of the sensor. To facilitate the alignment, horizontal and vertical adjustments must be completed separately. Vertical Alignment Adjustment Horizontal Alignment Adjustment To align the sensor: 1. Remove the sensor’s shell. 2. Fasten the telescopic sight (optional) with the quick release mounts. 3.
Web interface - Login 5. USER INTERFACE All settings to the sensor can be made through the web-based user interface. The instructions for the web-based user interface described below are valid for firmware 1.8 and higher. 5.1. FACTORY DEFAULT SETTINGS When using the sensor for the first time, or if a factory reset has been made, the following settings are used: Default IP address: 192.168.0.10 Default username: Default password: admin admin 5.2. LOGIN 1. Open a web browser. 2.
Web interface - Device configuration 5.3.2. Device configuration 1. Open the ‘Device configuration’ tab. 2. The sensor’s current network and user settings are shown. 3. 4. To change TCP/IP settings, press ‘edit settings’ under the network settings. Input fields will appear to the right. Modify the settings as needed and press the save button when done. If you change the sensor’s IP address, you will have to reload the page with the new IP address. 5. 6. 7.
Web Interface - Import & export settings 5.3.3. Import and export settings Alarm settings can be exported as a file for backup and to copy settings to other sensors. IP address and login settings are not included in the exported file. 1. 2. Open the Import and export settings tab. Export all current alarm settings by pressing the ‘Download’ button. Pay attention to the file location on your hard drive. The file name is individual for each sensor as it includes the sensor’s MAC address. 3.
Web interface - Firmware update 5.3.4. Firmware update The SiteWatch™ laser sensor’s firmware should be updated when new versions are available. To update the sensor’s firmware: 1. Open the Firmware update tab. The sensor’s current firmware version is displayed. 2. Press the ‘Update firmware’ button to enter the system bootloader. 3. In the bootloader, you have the option to upload a new firmware, clear all settings (restore factory settings) and restore to the factory firmware. 4. 5. 6. 7.
Web interface - Alarm settings 5.4. ALARM SETTINGS The SiteWatch™ laser has four types of alarms, zone alarms, reference point alarms, time/heartbeat alarms and weather alarms. All alarms are designed for network communication, but the built-in relay can also be used. 5.4.1. Zone alarms Zone alarms are standard alarms for object detection. Up to 20 zones can be created and each zone can have individual settings and alarm actions. 1. 2. 3. 4. 5. 6. Open the Alarm settings tab.
Web interface - Alarm zones actions 5.4.2. Alarm zones actions 1. Press ‘+ Add action’ under the desired alarm zone. Input fields appear on the right. 2. Choose the action event type from the options in the drop-down menu. ‘Relay action’ and ‘Connect to URL’ are available. For relay action, go to step 5. 3. If ‘Connect to URL’ is selected, enter the IP address to connect to, such as the VMS server. 4. Depending on the VMS, alarm disable URL may be needed. 5. Press the ‘Save’ button to confirm settings. 6.
Web interface - Reference point 5.4.3. Reference point Reference point alarm is a tampering alarm used to detect if the sensor has been moved or covered. Reference point alarm is possible only when the laser sensor is aligned in a manner where there is a reference object and the signal stability is good. To add a reference point alarm: 1. 2. In the Alarm settings tab, click on ‘Add alarm’. Select ‘Reference point’ from the ‘Input’ drop-down menu. 3. 4. 6.
Web interface - Timer / Heartbeat 5.4.4. Timer / Heartbeat The timer / heartbeat is a tampering alarm used to detect a cable break or product malfunction by periodically sending a short message to the server. To setup a timer / heartbeat alarm: 1. In the Alarm settings tab, click on ‘Add alarm’. 2. Select ‘Timer/heartbeat’ from the ‘Input’ drop-down menu. 3. 4. 5. Enter an alarm name for the new alarm. Enter the time interval in seconds.
Web interface - Weather alarm 5.4.5. Weather alarm The laser sensor is constantly evaluating the measurement signal to determine the weather intensity at a scale from 0 to 10. This allows users to create alarm actions based on weather intensity. 1. In the Alarm settings tab, click on ‘Add alarm’. 2. Select ‘Weather alarm’ from the ‘Input’ drop-down menu. 3. Enter desired threshold level on weather intensity alarm (default is 1). 4. Enter a timeout value, the shortest time the weather alarm is active.
