Objective

This article provides configuration for connecting external alarm device to VIGI NVR and the steps to configure alarm in/output.

Requirements

• VIGI NVR (such as VIGI NVR4032H)

• External Alarm Devices

Introduction

VIGI NVR (with Alarm In/Out Interfaces) supports external alarm devices, which can be used to trigger alarms after NVR events, or to detect environmental abnormalities and provide abnormal signals. The alarm input receives the alarm signal. There are various types of commonly used external detectors, such as sound sensors, infrared sensors, smoke sensors, etc. The alarm output sends out alarm signal. VIGI devices can trigger alarms through external alarm devices such as external alarm lights, sirens, buzzers, etc.

To complete the configuration, you need to finish both the hardware installation and software configuration.

Hardware Installation

Before connecting the external alarm device, connect the included terminal block to the corresponding alarm interface on the VIGI NVR.

Alarm In

Please connect the positive terminal (COM port, +) of the alarm input device to the alarm input port (ALARM IN 1-16) of the NVR, and the negative terminal (NO/NC port, -) of the alarm input device to the ground terminal (G) of the NVR, as shown below.

Note:

1. The ground terminal of the alarm input (ALARM IN) requires the use of the G terminal shown in the above illustration and cannot be connected to the G terminal of the ALARM OUT connector.

2. Normally Open (NO port) means that under normal conditions, the circuit is open and no current passes through the NVR, when the alarm is triggered, the current passes through the NVR and the NVR alarms.

3. Normally Closed (NC port) means that normally the circuit is closed, and the NVR will alarm in case of a circuit fault or alarm trigger.

Alarm Out

The alarm output can be connected to either DC or AC loads. When used as a control switch for AC circuits, it is imperative to use an external relay to avoid damage to the equipment and the risk of electric shock.

Power by DC

Please connect the positive terminal (+) of the alarm output device to the positive terminal of the NVR alarm output port (ALARM OUT), marked 1~4. Then, connect the negative terminal (-) of the alarm output device to the corresponding ground terminal (G) of the NVR alarm output port (ALARM OUT).

Notes:

1. The alarm output port of the VIGI NVR is compatible with DC loads of up to 24V.

2. The NVR alarm output port (ALARM OUT) positive pole (marking 1~4) and the corresponding ground terminal (G) must be connected in a one-to-one manner, and cannot be mixed.

Power by AC

Please be aware that the normal AC load voltage is too high to trigger the alarm. Consequently, when external AC loads are connected, it is necessary to use an external relay, as illustrated in the schematic below.

Software Configuration

After connecting the external alarm device to the VIGI NVR, we need to configure alarm device on the VIGI NVR GUI or Web interface.

Alarm Input

Step 1. Select the Alarm input port from A1 to A16, we can also modify the Alarm Name for the port.

Step 2. Enable this alarm input.

Step 3. Select the Alarm Type.

Normally Open (NO) means that under normal conditions, the circuit is open and no current passes through the NVR, when the alarm is triggered, the current passes through the NVR and the NVR alarms.

Normally Closed (NC) means that normally the circuit is closed, and the NVR will alarm in case of a circuit fault or alarm trigger.

This depends on the type of alarm input device.

Step 4. Set up Arming Time. The Alarm input will only work during the set time interval.

Step 5. Configure Linkage Method.

For Regular Linkage, we can choose ‘Buzzer’ and ‘Screen Prompt’, or ink with any output port, when the alarm is triggered will let the linked port output signal.

For Recording Linkage, we can also choose to link with any channel, when the alarm is triggered will let the corresponding channel start video recording.

Alarm Output

Step 1. Select Alarm Output port from A1 to A4, we can also modify the Alarm Name for the port.

Step 2. Duration of device alarms.

Step 3. Arming Time settings. The Alarm output will only work during the set time interval.

Step 4. Set the alarm linkage on the Event setting page.

Conclusion

You have successfully set external alarm devices on VIGI NVR.
