What are thermal security cameras and how do they work?
In the world of surveillance and security, equipment has evolved to offer new proposals with more efficient technology. Thermal security cameras, tools for perimeter protection, like those that exist today, allow you to obtain a clearer view in the dark or in adverse weather conditions, unlike conventional cameras. This is possible thanks to a mechanism that allows body temperature to be detected through infrared sensors. Let’s see why these devices offer so many advantages and what their main features are.
Main benefits of thermal cameras in perimeter security
Although these thermal security cameras are a very popular option today, their origins date back to World War II. In fact, through this technology with this infrared radiation, enemies could be detected in the dark.
Throughout this time, advances have been significant until reaching the 80s and 90s, when it began to be integrated into perimeter security systems. The advantages are numerous, as we explain below:
- Total vision in the dark. These cameras detect the heat emitted by a person, animal or object, allowing them to be distinguished more clearly, even if there is poor lighting.
- Prevention and perimeter security. It is a key tool to monitor large areas and reinforce security against possible threats and critical situations, such as responding to an emergency.
- Reduction of false threats. This high-precision technology has been designed to avoid false alarms, identify intruders or any anomaly in movement or light change.
- Efficiency in adverse weather conditions. When weather conditions are adverse, whether due to heavy rain, fog or smoke, these devices obtain clear images.
Applications of thermal cameras in perimeter protection
Thermal cameras represent a true innovation in perimeter protection to guarantee a higher level of security. Today, they are used in different environments where the demands are greater, such as in different industries, airports, power plants and even in border areas. In addition, we can find more advanced equipment with artificial intelligence and video analysis to improve the response to a possible threat.
These surveillance equipment can also be used on construction sites, especially if long distances have to be covered. It is a good option because not requiring lighting reduces costs and improves efficiency. Additionally, if used in conjunction with an alarm verification service specialized in perimeter protection systems, real-time surveillance is improved. Thanks to their high reliability, they have become a recommended solution in higher risk environments.
Differences between thermal cameras and conventional security cameras
At this point, the most normal thing to do is ask ourselves what the differences are between conventional surveillance cameras and this technology. Below, we explain the most notable points to appreciate this superiority.
Technology for capturing images
Thermal cameras work through infrared radiation that allows people, animals and objects to be detected, even in total darkness or adverse conditions. Instead, conventional security cameras rely on ambient lighting for sharper images.
Performance in adverse conditions
Thermal security cameras guarantee greater effectiveness in extreme weather conditions, where visibility is limited. However, conventional monitoring equipment could be affected by these meteorological factors. In most cases, it is quite difficult to obtain a clear and accurate image.
False alarm detection
Since these security cameras are designed to detect the temperature of living things and even inanimate objects, it is easier to distinguish a false alarm. On certain occasions, a change in light or the movement of a simple branch could be mistakenly interpreted as a potential threat.
The cost and applications
A thermal security camera for perimeter protection is usually somewhat more expensive due to the features it offers. However, it is a worthwhile investment, for this reason, its use is increasingly popular in urban, commercial and industrial environments. Although the choice will depend on the protection needs required.
How to choose a thermal camera for perimeter security
Choosing a thermal camera to ensure the security of a facility or property is not always easy. There are certain factors that we must take into account to achieve good performance. These are some of them:
- Detection capacity. Make sure the camera provides effective response based on distance and perimeter size.
- Thermal resolution. The images are more precise and detailed as the thermal resolution is higher.
- Equipment sensitivity. This characteristic refers to the ability to detect small temperature variations.
- Integration with other systems. Not all systems are compatible with other equipment, such as alarms, among others.
- Budget. It is advisable to do a prior analysis of your needs to choose a camera that maintains a balance between quality and price.
Maintenance and care of thermal cameras for optimal performance
If we want to guarantee optimal performance and extend the useful life of these security cameras, proper maintenance and care is advisable. Periodic cleaning is essential to avoid the accumulation of dust, both on the equipment, its components and the lens. In addition, special attention must be paid to the connections and sensors to ensure their proper functioning. Qualified service reduces the risk of security breaches.
Installing thermal security cameras is a very advantageous solution for any environment that requires a higher level of protection.
