Your first layer of defense

AXIS Perimeter Defender gives you an edge where security starts—at the perimeter of your facilities. 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 for high-security sites such as chemical plants, power plants and prisons.

High reliability

AXIS Perimeter Defender is designed to detect moving people and vehicles (up to 7 m or 23 ft. in length). It uses a three-dimensional representation of a scene to enable highly accurate detection. Because it can classify people and vehicles, you can select if you want to detect only people or vehicles, or both.

AXIS Perimeter Defender minimizes false alarms in a number of ways. The application automatically learns—after at least a day’s installation—the difference between “day” and “night” and uses this information to fine-tune the algorithm for optimal performance. It automatically handles variable illumination and disregards motion that are not from humans or vehicles—such as swaying vegetation and fast-moving shadows on the ground. It can also mitigate false alarms from headlights. The application supports multiple detection scenarios simultaneously so you can tailor the setup to your needs.

AXIS Perimeter Defender’s high detection accuracy and minimal false alarms, especially when combined with thermal network cameras, enable a system that is highly reliable.

Detection scenarios

AXIS Perimeter Defender can detect and trigger an alarm using four different types of scenarios:

  • Intrusion: When one or more persons or vehicles enter a predetermined zone
  • Zone crossing: When a person or vehicle passes through two predetermined zones in a predetermined order and direction.
  • Loitering:  When a person or a vehicle remains in a predetermined zone for more than a certain number of seconds.
  • Conditional zone crossing: Triggers when a person or a vehicle enters a predetermined zone without starting in or passing through one or more predetermined zones. 

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 -- available with Axis network video products with firmware version 7.30 and higher -- 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 analytics application that can be embedded in as many network cameras or video encoders as required. The application analyzes the video for alarm events directly on the network camera or video encoder. 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.

PTZ autotracking

With the additional purchase of AXIS Perimeter Defender PTZ Autotracking license, a fixed camera running AXIS Perimeter Defender can automatically take control of a PTZ camera to zoom in on and track alarm objects in the fixed camera’s detection area.

The fixed camera sends the location data of the alarm objects to the PTZ camera, thereby controlling the direction and zoom level of the PTZ camera. The PTZ camera automatically adjusts the zoom level to keep all alarm objects in view.

This functionality allows you to maintain continuous detection coverage of a scene with a fixed visual or thermal camera while being able to automatically track and get closer views of alarm objects with a PTZ camera. You get the details you need without having to manually control the PTZ camera—and without compromising on detection. If you are an operator, you can take manual control of the PTZ camera at any time, especially after the PTZ autotracking stops when objects move out of the fixed camera’s detection zone.

The PTZ autotracking functionality works only on specific Axis PTZ cameras (see list) and can only be used to pair up one fixed camera with one PTZ camera. Proper placement and mounting of the PTZ camera, as well as good calibration are key to the autotracking function. The PTZ camera should be able to share, as much as possible, a field of view similar to that of the fixed camera.

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.

Easy and efficient management

AXIS Perimeter Defender’s installation program lets you connect and configure multiple cameras simultaneously using a single interface and from one location. The same interface is also used to pair up a fixed camera with a PTZ camera for automatic PTZ autotracking.

The program supports automatic calibration of the analytics on the cameras to simplify setup. It also lets you configure each camera’s detection scenario and response to alarm events. You can then integrate the events with any video management software that supports event handling and video streaming from Axis cameras. Support and upgrades are included in the AXIS Perimeter Defender software license.

How to buy

AXIS Perimeter Defender software includes the analytics application for compatible cameras and video encoders, as well as a separate application for PTZ autotracking. Each camera requires one AXIS Perimeter Defender application license and a separate license for the PTZ autotracking functionality if it is required. You can buy from an Axis Channel Partner single or 10-pack license codes for the AXIS Perimeter Defender analytics application. The PTZ autotracking application sells as single license codes and is available initially for sale in selected countries. The licenses can be activated through the license key registration page.
