How To Use IVS Features (AI NVR)

IVS stands for intelligent video system analytics and provides advanced perimeter protection options such as tripwire and intrusion. IVS features can be controlled by the NVR or by the camera directly if using a smart plan. The NVR has 2 built-in IVS features available (Tripwire and Intrusion) whereas some Amcrest AI cameras may have additional IVS features depending on the model of the camera.

Both IVS rules and Heat Map features can be used simultaneously in the system. For more information on how to set up the Heat Map feature, click here.

IVS rules on the NVR are controlled either by camera or by the NVR. The NVR currently has 2 built-in IVS features available (Tripwire and Intrusion) whereas some Amcrest AI cameras may have additional IVS features. For more information on how to setup IVS and heat map, please refer to the information provided below.

Note: Please make sure to completely disable any face detection, face recognition, people counting or other AI features when using IVS rules.

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 IVS option. Both Heat Map and IVS smart plans can be active at the same time if necessary. Click on Apply (Save).

Step 3: Click on the IVS option located in the Parameters menu and verify the correct channel is being used. If you are using AI features available on the camera side, select AI by Camera, in this example, we will be using AI by Device to highlight key features of the NVR. Click Add to add an IVS rule.

IVS Features Available by Device

Any camera, whether AI or non-AI, connected to the NVR can take advantage of the NVRs built-in AI features, including IVS. For more information on the built-in IVS features please refer to the information provided below. 

Tripwire: Allows the device to trigger an event if an object, such as a human or vehicle, crosses a set tripwire line.

Intrusion: Allows the device to trigger an event if an object, such as a human or vehicle, appears or crosses a set intrusion area.

Step 4: Click on the Type drop-down menu to select an available IVS rule. Once a rule is selected, click on the Draw (pencil) icon, to begin configuring the rule.

Step 5: Use your mouse to draw an area or line on the interface. Click on the interface and use your mouse to draw an area or line, click your mouse on the interface when done, then right-click to set the area or line to the system.

If you would like to add a name to the rule, enter a name in the Name box. The Direction drop-down menu allows you to choose a direction in which the rule will be triggered. Object filters can be enabled for accuracy. Click Save.

The Target Filter option is used to set a minimum or maximum detection area. It is recommended to leave this as default; however, it can be modified. Use the Clear (trash can) icon to remove a drawn area or line. The AI Recognition toggle switch enables object filtering options that allow you the ability to determine if a human or vehicle has entered the area. If Person is chosen, the rule will only be triggered if a human figure is detected. If Vehicle is chosen, the rule will only be triggered if a vehicle is detected by the system. Both object filtering options can be used simultaneously if needed.

Step 6: If you would like to add multiple rules to the device, click on Add and repeat the IVS setup process for the rule. Click Apply once all IVS rules are set.

Use the Trigger (gear) icon to apply any additional settings to an IVS rule, such as enabling email snapshots, etc. To delete an IVS rule, click on the delete (trash can) icon.

Note: Once an IVS rule is triggered the line or area visible on the live view screen will flash.

How To View IVS Data

Any IVS data retained on the system can be viewed using the IVS Smart Search interface or via the playback menu if an IVS schedule is set in the system.

To view IVS data using the IVS smart search interface, click on the IVS option located in the Smart Search menu. Enter a start and end time of the event and click Smart Search. A layout of all IVS events will be displayed. To view the event, select the event from the interface, and click the play button. The event can also be stored using a USB flash drive.
