Your first layer of defense

AXIS Perimeter Defender gives you an edge where security starts – at the perimeter of your site. The video analytics application, together with Axis network cameras, provides a highly effective system that automatically detects and responds to people and vehicles intruding on your property. It reinforces physical access controls, and is suitable even for high-security locations such as chemical plants, power plants and prisons.

Intrusion detection

AXIS Perimeter Defender analytics detects and classifies moving people and vehicles. For selected cameras, the analytics also supports human and vehicle classifications based on AI (artificial intelligence).

The analytics application can trigger an alarm using multiple detection scenarios based on predefined intrusion zones, zone crossing, conditional zone crossing and loitering. It minimizes false alarms by ignoring variable illumination, swaying vegetation and fast-moving shadows on the ground. It offers functions that help filter out alarms caused by headlights, insects and water on a camera lens.

Metadata overlay

During configuration, AXIS Perimeter Defender automatically applies a metadata overlay in the form of bounding boxes and trajectories that show the detection and tracking of moving people and vehicles. You can then choose to apply a burnt-in metadata overlay in live and recorded video. This feature applies red boxes and trajectories for people, and blue boxes and trajectories for moving vehicles. This allows you to get visual confirmation of the objects being detected. This is particularly helpful when viewing thermal video.


AXIS Perimeter Defender is a scalable, edge-based analytics application that can be embedded in as many network cameras as required. The application analyzes the video for alarm events directly on the network camera. Since the video is not sent to a central server for analysis, there is no need for additional and costly processing hardware. It makes the system flexible and scalable, and also minimizes the use of network bandwidth and storage space.

Event management

AXIS Perimeter Defender integrates with an Axis camera’s event management functions. This means you can decide how you want the system to automatically respond to intruders. Having the camera send live video and email alerts to security staff allows a guard to focus on potential problems and take preventive action. Setting the camera to send and record video only on alarm also makes reviewing and searching for incidents easier. You can also program the camera to activate a loudspeaker to scare off intruders.


The AXIS Perimeter Defender software comes with an installation program that lets you remotely upload the applications for the analytics and PTZ autotracking (separate license required) to multiple cameras simultaneously – using a single interface and from one location.

The program supports automatic and manual calibration of both applications. For selected cameras with support for AI-based object classifications, there are two additional options for setting up the analytics: AI mode without calibration, or calibration and AI modes combined for minimal false alarms. Note that the PTZ autotracking function is not supported when using only the AI mode because the PTZ autotracking feature requires the analytics to be calibrated. Support and upgrades are included in the AXIS Perimeter Defender software license.

How to buy

AXIS Perimeter Defender software includes the analytics application, as well as a separate and optional application for PTZ autotracking. Each fixed camera requires one AXIS Perimeter Defender analytics application license – single or 10-pack license codes are available. A separate license for the PTZ autotracking application is required for a PTZ camera – single license codes are available. The licenses can be activated through the license key registration page.
