Safeguarding outdoor assets, whether commercial sites like maintenance yards and car lots or critical infrastructure protection like airports and refineries often comes down to the same thing: Accurate detection and timely information about the unfolding event. While there are many technologies for outdoor security, combining reliable alerts with knowledge about what is actually happening and where […]
To achieve success with a video solution, it’s important to carefully consider the difference between video security and video surveillance. While both play an important role for protecting outdoor assets, understanding how and where they differ can be critically important when selecting an effective solution to meet your security objectives.
Our eyes work by seeing contrast between objects that are illuminated by either the sun or another form of light. A thermal camera operates by “seeing” heat energy from objects. All objects – living or not – have heat energy that thermal cameras use to detect an image. This is why thermal cameras can operate at […]
Video analytics are a valuable tool to protect outdoor assets either at the perimeter or around critical assets. Here are some pointers to keep in mind when deploying smart cameras for outdoor security. Choose video analytics specifically designed for outdoor use Smart cameras operate by sensing movement, but outdoors everything moves, including the camera itself. A camera […]
Incorporating global positioning system (GPS) location information into perimeter security applications is the cornerstone of dependable, accurate video intrusion detection. The key is to use intelligent videos solutions that have been designed from the ground up to be inherently “geo-registered.” This means that the camera’s field of view (FOV) maps the GPS coordinates of all points in the landscape under surveillance. Such an approach is fundamental to achieving high performance and accuracy in an intelligent video surveillance system.
All security cameras have perimeter camera blind spots, which must be considered in the perimeter design as this area can cover a meaningful portion of the camera’s overall range. Many outdoor surveillance designs will narrow a security camera’s field of view to increase the camera’s detection distance in an effort to decrease costs. However, doing so […]
A perimeter security system based on video analytics operates by “seeing” targets that move into a camera’s detection area. Unfortunately the practical real-life detection range of a camera doesn’t always match the manufacturer’s published specifications. This means it’s up to the integrator to test and determine the camera’s true detection distances. Knowing the camera’s true range lets […]
The key to accurate video perimeter security systems is to know the location of all objects so their size can be accurately determined. This information can be used to set size filters that eliminate movement that does not represent a security concern, while detecting human-sized intruders under all conditions.
