Factors for efficient video technology in the context of perimeter security

The perimeter is the first line of detection in security systems for buildings and premises. How efficient security solutions are determines the effectiveness of the entire security infrastructure and also whether an unwanted incident can be prevented before it occurs. Modern solutions offer various options for protecting a site. These range from different types of video surveillance cameras to motion sensors, analysers, thermal cameras or even radar or LiDAR.

The basis of all solutions among all these options is still the surveillance cameras to provide evidence in image and sound.

However, installing surveillance cameras outdoors brings some challenges. Temperature is an important factor when operating cameras. Extremely low temperatures can have a negative impact on any surveillance camera. Cameras can freeze, erode and form ice deposits on the lens that can cloud the view. In worse cases, the unit may not turn on at all.

Condensation is a major problem that limits visibility and damages electronics. In surveillance cameras, condensation can cloud the lenses and cause the electronic components to erode over time. If cameras are installed in a location where they are constantly exposed to air pressure fluctuations and rain, there is a risk that seals and components will crack, causing moisture to accumulate inside.

Weather conditions are not the only enemy of surveillance cameras. If the cameras are located in a maritime environment, the salt content in the air can cause the equipment to corrode over time. A similar problem arises if the camera is used in medical or industrial areas where strong chemicals are used.

By observing the IP rating (IP = Ingression Protection), protection from outdoor conditions is possible. The IP 66 rating protects against solids such as dust and liquids such as rainwater, providing a high level of protection. It is also important to pay attention to the correlation of the operating temperature with the temperature of the installation location. In general, the installation location has a great influence on how well a camera works. The quality of the surfaces on which cameras are mounted is also important. This is because they can easily transmit temperatures and thus also influence the operating temperature.
