The AXIS Q8742-E is a positioning camera that brings a powerful – and cost effective – combination of visual and thermal video streams in a single PTZ camera to border surveillance and other applications with similar requirements.
The Q8742-E gives you two excellent cameras in one: a thermal camera with outstanding contrast in 640x480 resolution for reliable detection and verification around-the-clock and in all weather and light conditions. And an exceptionally light-sensitive visual camera in HDTV 1080p with integrated 30x optical zoom for identification purposes.
The visual camera also has Wide Dynamic Range – Forensic Capture for clarity and detail in scenes with both dark and light areas. And Focus recall for instant focus in areas you define.
Swift, smooth 360° coverage
Operators can choose between really slow or super-fast pan (from 0.05 to 120 degrees per second) and tilt movement (from 0.05 to 65 degrees per second). They get smooth and jerk-free panoramic viewing when they need it and can respond quickly to events.
The camera can be column-mounted, on poles or walls for a 360° panoramic view and a ground-to-sky view from -90° to +45°. It can withstand high winds when it’s standing still and winds of up to 37-meter per second (83 mph) when it’s in motion. And an SFP slot means it supports long-distance fiber-optic connection.
The Q8742-E is a highly cost-effective solution. You need just one camera and one IP address to benefit from long-distance thermal detection, visual identification and PTZ capabilities. Which means lower purchase, installation and operational costs. In addition, Axis Zipstream technology reduces storage and bandwidth needs with up to 50% or more while ensuring that important details are captured in full image quality.
Fast and easy
Its slim design and many available accessories let you install it anywhere you want. It has an SFP slot, so it supports cost-effective, long-distance fiber-optic connection . And maintenance is made simple by a remote-control cleaning system that features long-life wipers. A 22 meter (72 feet) long, heavy-duty power cable is available as optional accessory. Designed for outdoor use, the cable has 3-wire, 12AWG and a jacket diameter of 10 mm (0.4 in).

The detection ranges are calculated with Johnson’s criteria and vary in different weather conditions.
The role of intelligent thermal cameras
Detect: Thermal cameras detect suspicious behavior and objects even in dark scenes and other difficult light conditions.
Verify: As soon as a thermal camera has detected something suspect, an operator can verify that the activity is really a threat.
Act: Once activity has been verified as suspicious, the thermal camera, acts in response. For example it can:
- Automatically notify security
- Trigger visual cameras to identify people or vehicles
- Trigger lights or a speaker to deter the crime
Inside a thermal camera
Thermal cameras work because all objects – organic or inorganic – emit a certain amount of infrared radiation as a function of their temperature.
Like all cameras, thermal cameras collect electromagnetic radiation, which is formed into an image. Conventional cameras work in the range of visible light, in other words, with radiation with short wavelengths. Thermal cameras, on the other hand, detect radiation with mid-length or long wavelengths, which is called infrared radiation.
The main difference between infrared radiation and radiation with a shorter wavelength is that infrared radiation is emitted rather than reflected. Since the object themselves emits the light (heat) thermal cameras detect, thermal cameras are not dependent on visible light and can detect in all light conditions, day or night.
