Thermal network cameras outperform a visual camera in dark scenes and are a great tool for detecting people and objects in 24/7 surveillance, from pitch dark areas to a sunlit parking lot.
Thermal network cameras create images based on the heat that always radiates from any object, vehicle or person.
A thermal camera is less sensitive to problems with light conditions, such as shadows, backlight, darkness and even camouflaged objects; and delivers images that allow operators to detect and act on suspicious activity – 24 hours a day, seven days a week.
Thermal cameras are excellent for detecting people, objects and incidents from pitch dark to sunlit and other challenging conditions. Thermal cameras do not, however, deliver images that allow reliable identification – that is why thermal cameras and conventional cameras complement and support each other in a surveillance installation.
Thermal cameras do not require any additional light sources – conventional or IR – that consume energy, create shadows and reveal their locations. And, in contrast to conventional day-and-night cameras that depend on a certain amount of near-infrared light to function, thermal cameras deliver reliable surveillance images even in complete darkness.
Enhancing any professional IP-Surveillance system
Thermal cameras can handle many difficult weather conditions better than conventional cameras, e.g. allowing operators to see through smoke, haze and dust. Thermal cameras typically also provide better accuracy in intelligent video applications.
When you need reliable 24/7 detection with a low rate of false alarms, thermal cameras are the obvious choice.
Since living objects, such as humans, often have a different body temperature than their background, thermal cameras are excellent at detecting humans in a wide range of circumstances. In addition, objects such as vehicles also have a different temperature than the surrounding environment, making detection easy.
Thermal cameras can be used in a wide range of security applications, such as perimeter protection around industrial sites, airports and power plants. Their detection capabilities also make them a valuable tool in, for example, search and rescue operations.
Some thermal cameras, which we at Axis call temperature alarm cameras, are able to measure absolute temperature values. They can be used, among other things, when monitoring industrial processes, or acting as a fire alarm, or monitoring fridges at the supermarket.
The built-in intelligence of the camera, together with added video analytics, creates a solution where the video surveillance system automatically performs an analysis of the captured video. Thermal network cameras help distribute this analysis to other cameras in the IP system, leading to improved efficiency and scalability.
All in all, thermal network cameras make sure that objects, people, and incidents are detected 24 hours a day, seven days a week. Together with video analytics, thermal cameras help reduce the rate of false alarms and keep installation costs down since fewer cameras are needed to monitor the area.
Thermal cameras’ ability to detect humans, vehicles and animals can also be used in search and rescue operations, detecting people in the water in a harbor, helping firemen see through smoke, or allowing the police to follow perpetrators. Thanks to a variety of lens options, thermal cameras help covering everything from wide parking lots to long fences.
Invisible thermal fence for perimeter protection.
Thermal network cameras are an efficient perimeter protection. They are often a cost-effective solution, covering long distances with few cameras thanks to their ability to detect people against the background. If someone trespasses a fence, the security manager gets a verification image on his/her smart device.
Cut down costs!
With their low rate of false alarms, thermal cameras help security management cut costs on unnecessary responses by security staff. They can also be used to verify alarms, for example, to make sure that the motion detection alarm is actually triggered by a human. In this way, security staff can act, preventing costly vandalism or acts of crime.
Detect people for their safety and security!
In potentially dangerous environments, thermal network cameras improve safety in restricted places, such as tunnels, crossroads and railway tracks, which helps prevent accidents.
