AXIS OS features different firmware tracks depending on your needs. The active track provides access to the newest state-of-the-art features and functionalities, including bug fixes and security patches. In other words, in the active track, we focus on continuous software development. In the long-term support (LTS) track, we don’t add any new features. The focus is to improve cybersecurity and stability.
Alarm overlay is a type of metadata overlay. An alarm overlay is used in recorded and live video to draw the operator's attention to things that happen in a scene, such as an individual who lingered in a specific area too long. An alarm overlay can consist of different elements, but typically it includes a bounding box that appears or changes color when the alarm is triggered.
Through our AXIS camera application platform (ACAP), you also have access to a long list of tested, well-documented application program interfaces (APIs). These APIs are optimized for Axis devices and let you take full advantage of Axis hardware and software. Together with software development kits (SDKs) based on open-source components, they facilitate interoperability, scalability, and easy migration of your apps to execute on Axis devices.
A type of iris, which is electrically controlled by the camera, to automatically regulate the amount of light allowed to enter.
Axis Secure Remote Access is a technology that allows a smartphone or PC client to access Axis network cameras when the client and the cameras are located on different local networks. Axis Secure Remote Access significantly simplifies the installation of remote access to surveillance systems. Once enabled, it’s automatically configured and removes the need for manual port-forwarding and router configuration.
Barrel distortion correction (BDC) is a lens correction that digitally corrects barrel distortion, where the image of a square object has sides that curve out. Using sliders, users can pull the edges of the image to make the image appear flat rather than curved.
A bounding box is a type of metadata. A bounding box can help the operator to detect important details or draw the operator's attention to what happens in the scene.
A card reader is a device that can decode the information contained in a card’s magnetic strip or microchip.
Corridor format is a feature that lets users turn the camera view 90 degrees to give a vertical view (portrait) at, for example, 9:16 ratio rather than a horizontal view (landscape) at, for example, 16:9 ratio. With corridor format, you can use the full view of the camera to overlook narrow scenes such as retail store aisles, highways and freeways, school hallways, and train station platforms.
Sometimes referred to as day/night functionality. A camera with day-and-night functionality can pick up light in the near-infrared (NIR) wavelength range and produce images. In cameras with true day-and-night functionality, the IR-blocking filter is mechanically removed at night. As a result, the camera's overall light sensitivity is increased. Cameras of all shapes and sizes (such as fixed, fixed dome, and PTZ cameras) can offer day-and-night functionality.
A type of iris, which is electrically controlled by the camera, to automatically regulate the amount of light allowed to enter.
A digital signal processor is an audio processor that provides advanced sound compensation, which optimizes the sound to fit specific scenarios. In Axis network speakers, several sound optimization techniques such as frequency optimization, loudness compensation, and dynamic range control are built into the speakers themselves to deliver better audio quality in any environment.
Axis Edge Vault is a secure cryptogenic compute module (secure module or secure element) in which the Axis device ID is securely and permanently installed and stored.
Edge-to-edge technology is a way to make IP devices communicate directly with each other. It offers smart pairing functionality between Axis network cameras and Axis audio products such as network speakers, audio bridges, and amplifiers.
Electronic image stabilization (EIS) provides smooth video in situations where a camera is subject to vibrations. Built-in gyroscopic sensors continuously detect the camera’s movements and vibrations, and they automatically adjust the frame to ensure you always capture the details you need. Electronic image stabilization relies on different algorithms for modeling camera motion, which are used to correct the images.
Evidence management systems and evidence management software are both abbreviated EMS. Both terms are associated with body worn cameras. An evidence management system comprises the whole solution of integrated hardware, software, and storage. Evidence management software manages recordings and metadata from body worn cameras.
In Axis products, an event trigger is typically a detector of digital signals, audio signals, or physical events such as movements or a change in light. Users can set up rules for what should happen when one or more triggers are met. Usually, the word trigger is sufficient, and the word event can be left out. In newer Axis software and products, we use the term condition instead of trigger.
Focus recall is a feature that allows you to save focus areas to which the PTZ camera automatically returns when it moves into that view. This feature is especially useful in challenging lighting conditions, where the camera would have trouble finding focus. To use focus recall, you click a button when you’re satisfied with the focus of the current view, and the camera creates a focus recall area. Later, the camera automatically recalls the previously set focus for that view.
Axis cameras with wide dynamic range (WDR) technology make the difference between seeing important forensic details clearly and seeing nothing but a blur in challenging light conditions. The difference between the darkest and the brightest spots can spell trouble for image usability and clarity. Forensic WDR effectively reduces visible noise and artifacts to deliver video tuned for maximal forensic usability.
The frame rate is the frequency at which a video stream is updated. We measure frame rate in frames per second (fps). When there's movement in the video stream, you need a high frame rate to maintain good video quality.
The frequency response is the frequency range that a system (or any part of it) can respond to.
Transmission of data in two directions simultaneously, such as in a telephone conversation.
Gatekeeper is an analytics feature that makes the camera react to movement and move to that position automatically. After a few seconds of inactivity, the camera returns to its home position. Typically, the gatekeeper is used to monitor a gate or a specific area. The gatekeeper can also trigger other actions (such as reading a license plate or recording video) in the same camera, in other cameras, or in the VMS.
Transmission of data in two directions, in one direction at a time, as in a walkie-talkie system.
An i-CS lens is an intelligent CS-mount lens that allows for quick and easy installation. The i-CS lens has three motors, which enable automatic and remote control of generic features such as zoom, focus, and aperture. This way, you can repurpose the lens for different cameras and use cases.
IK ratings specify degrees of protection against external mechanical impact, measured in joules. The degree of protection ranges from IK01 up to IK10. The requirements are specified in the international standard IEC/EN 62262. IK08 rated products are protected against 5 joules of impact, the equivalent of 1.7 kg that’s dropped from 300 mm above the product. IK10 rated products are protected against 20 joules of impact, the equivalent of 5 kg that’s dropped from 400mm above the product.
An image sensor is a device that captures light and converts it into digital signals to form an image. The image sensor consists of photosensitive diodes, photosites, which converts the light into electrons. The electrons are, through several conversions, interpreted as pixels. Once an image is formed, it’s sent for processing in a stage that determines, among other things, the colors of each individual pixel that make up an image.
A set of smart features built into our speakers. It enables boundless integration possibilities and includes, for example, sensors, digital signal processing (DSP), and audio management software.

RFID is short for radio-frequency identification. It’s an identification technology that uses radio signals, (i.e., the electromagnetic or electrostatic coupling in the radio frequency (RF) portion of the electromagnetic spectrum) to identify an object, an animal, or a person.
A scene profile consists of a group of settings that are combined in a way that suits a particular scenario. When the user selects a scene profile, the camera automatically optimizes the exposure time, white balance, aperture, sharpness, contrast, and noise to suit that scenario.
Our AXIS Camera Application Platform (ACAP) allows you to install plugin-style apps on your Axis devices. This way, you can customize the feature set of your Axis devices and systems while maintaining a high degree of interoperability and scalability. The application programming interfaces (APIs) and ACAP software development kits (SDKs) are based on open-source components and support developers, at Axis and partner companies alike, in creating apps for a vast array of scenarios.
A boot process that consists of an unbroken chain of cryptographically validated software, starting in immutable memory (boot ROM). Being based on the use of signed firmware, secure boot ensures that a device can boot only with authorized firmware.
A slot for a small form-factor pluggable (SFP) transceiver. This type of transceiver supplies network devices, such as a switches or routers, with a fiber optic network connection.
The sharpdome feature offers innovative mechanics that make the entire dome rotate, in contrast to a conventional dome where the camera rotates inside the dome. Pan-tilt-zoom (PTZ) cameras with sharpdome are versatile, with a field of view that extends above the camera horizon. This means that refractions and other optical effects are kept to a minimum.
Signed firmware is implemented by the software vendor signing the firmware image with a private key, which is secret. When firmware has this signature attached to it, a device will validate the firmware before accepting and installing it. If the device detects that the firmware integrity is compromised, it will reject the firmware upgrade. Axis signed firmware is based on the industry-accepted RSA public-key encryption method.
The Session Initiation Protocol (SIP) is a protocol that initiates, maintains, and terminates multimedia sessions between different parties. Usually, these sessions consist of audio, but sometimes they consist of video. The most common applications of SIP include internet telephony for voice and video calls and instant messaging over IP networks.
Sound pressure level (SPL) is an objective measure of sound loudness. SPL is used to describe how loud a sound a product is producing. The higher the SPL, the louder the sound. It is a reference level, where 0 dBSPL equals the threshold of hearing, 120–140 dBSPL is painful, and 140 dBSPL equals irreparable hearing damage. To get the SPL, you measure the atmospheric pressure caused by a sound wave over a specified period of time. It's expressed in dBSPL.
A supervised input, or supervised I/O, allows you to detect tampering in external alarm systems. Beyond the active or inactive state, it's possible to detect if the wire has been cut or shortened.
TPM is short for Trusted Platform Module. A TPM is a component that provides a set of cryptographic features suitable for protecting information from unauthorized access. The private key is stored in the TPM and never leaves the TPM. All cryptographic operations requiring the use of the private key are sent to the TPM to be processed. This ensures that the secret part of the certificate remains safe even in the event of a security breach.
Two-way audio (also known as duplex audio) is a feature that allows Axis devices to both pick up and broadcast sound. For example, if you have an IP camera with two-way audio, you can both see and hear what's going on on your premises and, if the need arises, speak with visitors or intruders in real-time.
