How To Use Face Detection (AI NVR)

Face detection is used to allow your device to detect face events. This feature can be used either by the NVR or by the camera (if supported). For more information on setting up face detection, please refer to the information provided below.

Note: If using AI by Device, please make sure Smart Codec is disabled in the encode menu. 

Step 1: Access the AI menu via the main menu. 

Step 2: In the Parameters section, access the Smart Plan menu and click on the Face Detection option. The Face Detection option cannot be used simultaneously with other IVS smart plans. Click Apply (Save).

Note: If using a non-AI camera, a smart plan may not be available for the specific channel.

Step 3: Click on the Face Detection menu located in the Parameters section and select which channel to configure from the Channel drop down menu. Next, choose which face detection type you will be using from the Type drop down menu. In this example, we will be using AI by Device, however, you can choose AI by Camera to use the camera’s built-in face detection settings, if applicable. Enable the face detection toggle switch (checkbox) and click Apply (Save).

Note: It is best to leave the Rule settings as default, however, they can be adjusted by clicking on the Setting button. Use your mouse to adjust the minimum (Min) and maximum (Max) size of the face detection area.

Step 4: When triggered, the face detection event will be retained in the face detection smart search menu or snapshots of the event can be emailed to you. For more information on how to setup Email Alerts, click here.

Click on the "Send Email" checkbox if you would like Email snapshots of the event to be emailed. Click Apply (Save) to save the setting. 

How to View Face Detection Data

All face detection data retained by the system can be accessed via the Face Detection option located in the Smart Search menu. Enter a start and end date and time for the event you would like to view in the Smart Search interface and click Smart Search.

A display of all face detection data will be displayed along with facial attributes. Click on the event you would like to view, and a clip of the event will be displayed in the built-in player. Click on the play icon to view the event. 

Storing a Face Detection Event

Face detection events can be stored on a USB flash drive. Insert the flash drive into a USB port on the device then click the check box next to the event you wish to store. If you would like to store all files, click on the All checkbox at the top of the interface. Click Backup to store the event, or multiple events to the USB flash drive. There will be a “File Type” drop down menu, select MP4 from the file type menu can click Start.

Once the backup process is complete, click Save. The files will be stored onto your USB flash drive and the MP4 recordings can be viewed on a computer.
