Axis Q1921 - Indoor

Reliable detection in dark and challenging indoor conditions

  • Thermal imaging for IP-Surveillance
  • Standard Power over Ethernet
    PoE (IEEE 802.3af)
  • Multiple H.264 streams with
    individual palettes
  • Intelligent video capabilities

Detection in complete darkness

The AXIS Q1921 19mm indoor camera comes with a 19mm lens and 55° angle field of view. This thermal imaging network camera is a superior add on to any video surveillance system. If you require 24/7 surveillance regardless of light conditions, the AXIS Q1921 19mm is right for you.

This camera does not detect light, rather it utilizes thermal imaging which allows users to detect people, objects and incidents in complete darkness and difficult conditions such as smoke, haze, dust and light fog.


  • Power over Ethernet (Class 3): Installation is made easy and cost-effective with Power over Ethernet (IEEE 802.3af), which eliminates the need for power cables
  • The first Thermal Imaging Camera on the market with two-way audio support.

H.264 video compression

AXIS Q1921 19mm thermal network cameras support H.264 video compression, which reduces bandwidth usage and storage needs by up to 80% compared to Motion JPEG. The camera provides multiple, individually configurable video streams in H.264 and Motion JPEG. Each stream can have its own color palette setting.

Two-way audio support

AXIS Q1921 19mm is the first thermal camera on the market with two-way audio support, which allows the user to communicate with visitors and intr

Intelligent video capabilities

Since thermal cameras are immune to problems with light conditions and normal shadows, they can achieve higher accuracy than conventional cameras in most intelligent video applications. The AXIS Q1921 19mm thermal network camera offers motion detection, audio detection, and detection of tampering attempts. The camera also provides capacity for third-party analytics modules, including support for AXIS Camera Application Platform.


Power over Ethernet for easy installation

Installation is made easy and cost-effective with Power over Ethernet (IEEE 802.3af), which eliminates the need for power cables.

Global standardization

AXIS Q1921 Thermal Network Cameras supports ONVIF for interoperability between network video products.
