Hikvision NVR/DVR Auxiliary Input Configuration Guide: A Comprehensive Overview201

Hikvision, a leading manufacturer of video surveillance equipment, offers a wide range of Network Video Recorders (NVRs) and Digital Video Recorders (DVRs) that incorporate auxiliary input functionalities. These auxiliary inputs, often referred to as alarm inputs, provide a valuable mechanism for integrating additional security and monitoring capabilities beyond video surveillance. This guide provides a comprehensive overview of configuring and utilizing Hikvision auxiliary inputs, covering various scenarios and troubleshooting common issues.

Understanding Auxiliary Inputs

Auxiliary inputs on Hikvision NVRs and DVRs are typically digital inputs, meaning they recognize either a high or low voltage signal. These signals can be triggered by a variety of external devices, including:
Door sensors: Detect whether a door or window is open or closed.
Motion detectors: Trigger an alarm when motion is detected within a specific area.
Smoke detectors: Signal a fire alarm event.
Tamper switches: Indicate if a camera or other device has been tampered with.
Button switches: Manually trigger an alarm or event.
Other security sensors: A wide range of other security sensors can be integrated.

When an auxiliary input receives a signal (typically a change from high to low or vice-versa, depending on the configuration), it triggers an event within the Hikvision system. This event can then be configured to trigger various actions, such as:
Recording: Initiate recording on associated cameras.
Alarm notification: Send an alert to designated personnel via email, SMS, or other methods.
PTZ control: Control the position of PTZ (Pan-Tilt-Zoom) cameras.
Relay output activation: Trigger an external device, such as a siren or light.

Configuration Methods

The specific steps for configuring auxiliary inputs vary slightly depending on the Hikvision NVR/DVR model and the user interface (UI) version. However, the general process typically involves these steps:
Access the NVR/DVR interface: Connect to your Hikvision NVR/DVR via a web browser using its IP address. You'll need the appropriate login credentials.
Navigate to the settings menu: Look for a section labeled "System Settings," "Configuration," "Alarm," or something similar. The exact location depends on the UI version.
Locate the auxiliary input settings: Find a section specifically dedicated to "Auxiliary Input," "Alarm Input," or a similar designation. This might be within the "Event" or "Alarm" section.
Configure the input parameters: For each auxiliary input channel, you'll need to configure the following:

Input type: Specify the type of signal (normally open or normally closed).
Trigger conditions: Define the conditions that will trigger the auxiliary input (e.g., rising edge, falling edge, level change).
Event actions: Select the actions to be performed when the auxiliary input is triggered (recording, alarm notification, etc.).
Associated cameras: Specify which cameras should start recording when the input is triggered.
Alarm notification settings: Configure how and to whom the alarm notifications should be sent (email addresses, phone numbers, etc.).

Save the configuration: Once you've made the necessary changes, save the configuration to apply the settings.
Test the configuration: Manually trigger the auxiliary input using the connected device to verify that the configured actions are performed correctly.

Troubleshooting Common Issues

Here are some common issues encountered when configuring Hikvision auxiliary inputs and their possible solutions:
No response to the input signal: Check the wiring connections, ensure the input voltage is within the specified range, and verify the correct input type (normally open/closed) is selected in the settings.
Incorrect trigger conditions: Double-check the trigger conditions (rising edge/falling edge) to match the signal behavior of your connected device.
Alarm notifications not received: Verify the email/SMS settings, check for network connectivity issues, and ensure the correct recipient information is provided.
Recording not initiated: Check that the associated cameras are properly configured and that the recording settings are correctly defined for the auxiliary input events.
Incorrect relay output behavior: Ensure the relay output is configured correctly and that the connected device is compatible.

Advanced Configurations

More advanced configurations may involve using multiple auxiliary inputs, integrating with third-party systems, or employing more sophisticated event management rules. Consult the detailed user manual for your specific Hikvision NVR/DVR model for advanced features and capabilities. Remember to always prioritize security best practices when configuring your security system and consider regular maintenance and testing to ensure optimal performance.

By properly configuring the auxiliary inputs on your Hikvision NVR/DVR, you can significantly enhance the overall functionality and effectiveness of your security system. This integrated approach allows for a more comprehensive and responsive security solution, providing proactive alerts and streamlined event management capabilities.
