Step-by-Step Guide to Integrating a USB-Powered Siren with Your Hikvision DVR Alarm Port

Enhancing your Hikvision DVR security system by integrating a USB-powered siren is a straightforward process that can significantly boost your security measures. This guide will take you step-by-step through the integration process, allowing the siren to trigger based on specific events detected by your DVR.

Step 1: Gather Necessary Materials

Before you begin, make sure you have the following materials:

• USB cable (you can use an old mobile charging or data cable)
• 5-volt power siren or buzzer

Step 2: Prepare the USB Cable

1. Cut the Charging Connector: Use a pair of scissors to cut the charging side connector of your USB cable to access the internal power wires.
2. Strip the Wires: Typically, a USB data cable contains four wires—red, black, white, and green—while a charging-only cable usually has two wires (red and black).
   • For a data cable: Use the red (positive) and black (negative) wires for power.
   • For a charging cable: Again, use the red and black wires and remove any additional data wires.

Step 3: Connect the Siren

1. Identify the Wires: Confirm that the red wire is connected to the positive terminal and the black wire to the negative terminal of the siren.
2. Connect to DVR: Use the USB cable to connect the siren to the DVR’s USB power output, making sure to observe the correct polarity (+ and -).

Step 4: Ensure Power Supply

1. Power on the DVR: Make sure your DVR is turned on.
2. Test the Siren: The siren should produce sound through this direct connection. This confirms that the siren is functioning correctly with the DVR’s USB power.

Step 5: Connect to the Alarm Port

1. Disconnect the Negative Wire: If the siren sounds as expected, disconnect the negative wire from the siren.
2. Secure the Connection: Use insulation tape to secure the USB negative wire to prevent any short circuits.
3. Touch the Negative Wire to GND: Briefly touch the siren’s negative wire to the DVR panel’s alarm output port ‘GND’ terminal. This step confirms that the siren is functional as the DVR alarm port provides ground (negative supply).
4. Connect the Negative Wire: If the test is successful, finally connect the siren’s negative wire to the DVR alarm output port terminal.

Step 6: Configure the DVR Settings

1. Log in to the DVR: Use your admin credentials to log in to your DVR.
2. Access the Configuration Page: Navigate to the ‘Event’ section to configure alarm events, such as video loss.
3. Enable Event Notifications: In this demonstration, we will use the video loss alert as an example. Set up different events based on your security needs, such as motion detection or line crossing.
4. Link the Siren: Ensure you check the ‘Local 1’ option in the ‘Linkage Action’ section under the ‘Alarm Output Linkage’ tab to activate the siren for specified events.

Step 7: Finalize Setup and Testing

1. Configure the Arming Schedule: Decide when you want the siren to be active and configure the arming schedule.
2. Conduct Final Tests: Ensure that all configurations are working correctly. Trigger events to confirm that the siren activates as intended.

Conclusion

Congratulations! You have successfully integrated a USB-powered siren with your Hikvision DVR security system. This setup not only enhances your security but also allows you to receive timely alerts for specific events.
