Axis is broadening the horizon for thermal cameras
Why use thermal cameras?
Not all cameras can see in the dark, but with the thermal cameras range from Axis, even pitch-black darkness doesn’t offer a place for criminals to hide. Thermal cameras give 24/7 protection for perimeters, property and people by being able to detect small temperature differences in objects, vehicles, people, or animals to raise an alarm if a potential intruder is detected.
By using the heat signatures given off by certain objects, rather than relying purely on the visuals of an area, the cameras can form images of a scene without needing to use light. Then, using smart analytics from Axis, the thermal cameras can use advanced algorithms to analyze what’s happening in the scene against pre-programmed variables to trigger an event/alarm.
This means that if the object detected meets the threat criteria, an alarm is raised. As the cameras are recording the scene, the central controller can then look at the situation and verify if it is a real threat or a false alarm and take the necessary action, all in real-time.
Additionally, thermal cameras can cover longer distances by using different lens options to monitor a wide area. This is particularly useful for perimeter protection or remote locations with wide spaces such as industrial plants or border control applications. If it is impractical for a security guard to get to the scene straight away, additional measures can be triggered, such as floodlights or an audio deterrant to scare away a potential intruder.
Monitoring without compromising privacy
By having thermal cameras as part of an organization’s security and surveillance system, users can be assured that any untoward activity will be detected and acted upon, without compromising the individuals’ privacy.
In a world that is more privacy conscious than ever, users who are using thermal cameras for security surveillance can ensure they are being compliant by not capturing images of an individual’s face. By using heat to map a scene rather than visuals, the privacy of those in the scene is not compromised as it is their shape, rather than their facial features that is used in the video stream.
This is important in applications such as monitoring patients in healthcare facilities, where the use of small form factor thermal cameras means patient safety can be monitored without infringing on their privacy. In this case, a thermal camera is placed at the end of a patient’s bed with a predefined line. If this line is breached for any reason, the staff on call will be alerted and can verify if they need to act. This is extremely useful when looking after patients who are unstable on their feet, such as the elderly or recently post-op who are more likely to fall out of bed.
Unusual heat detection
As well as identifying objects and people based on the heat they emit, thermal cameras can see where there are unusual heat spots, or higher-than-expected temperatures. For example, they can be placed in a server room to detect overheating. If the server reaches a certain temperature, security or safety teams can be automatically alerted by the thermal surveillance system so action can be taken before a fire breaks out.
Having thermal cameras as part of an organization’s surveillance system can offer many operational and logistical benefits, but it can also do this with cost savings, making them a more viable option for many more companies.
Together with analytics, thermal cameras can detect across farther distances than visual cameras, so fewer cameras are needed to monitor an area. The more reliable detection and verification means fewer false alarms are produced so personnel can fully focus on other important tasks. Furthermore, when combined with Axis Zipstream technology, bandwidth and storage requirements are dramatically lowered for many common surveillance situations. Thermal cameras provide an out-of-the-box, quick and easy installation, as well as being tough and durable – withstanding even the harshest weather conditions.
