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 for 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.

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 deployment and management

AXIS Perimeter Defender enables efficient installation and configuration of the application on multiple cameras simultaneously. A design tool and automatic calibration simplify setup. Support and upgrades are included in the license.

Simply download and install the software on your PC. In the application, connect and configure the cameras, integrate the events with your video management system, and you're up and running.

How to buy

Single or 10-pack license codes can be purchased from an Axis Channel Partner. One license is required per camera. The license can be activated through the license key registration page. A 60-day trial version is available online.
