Below you’ll find outdoor security best practices, tips and advice for using perimeter intrusion detection solutions to protect outdoor areas.
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.
Trying to manually steer a PTZ to identify an intrusion is like trying to find a needle in a haystack. The solution is to a use a hands-free, auto tracking PTZ camera that automatically zooms and follows an intruder in real time.
For perimeter security applications covering large outdoor areas, using a long range thermal camera with video analytics offer significant economic advantages. To leverage extended range products effectively, it’s important to consider several best practices of product selection and deployment.
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.
Achieving accurate perimeter security for outdoor areas comes down to knowing the nature and location of an intrusion, allowing an effective response. While there are a number of options available for perimeter security, using a thermal camera with video analytics has become a strong contender for best-of-breed in this area. Thermal video analytic cameras operate […]
When outdoor conditions are ideal, thermal cameras can “see” what the eye cannot, even in complete darkness. Problems occur when rain, humidity, and other outdoor conditions bring background temperatures close to the temperature of objects which represent security concern, such as a person entering an unauthorized area. When background temperatures closely match the heat of a person, […]
When deploying a thermal camera to protect site perimeters, it’s important to choose a system specifically designed for outdoor use in order to reduce nuisance alarms and maximize detection accuracy.
Thermal cameras operate by sensing heat from objects. All objects – living or not – emit heat that thermal cameras can detect due to their sensitivity. Because heat is always available, day or night, thermal cameras can operate at all times, ranging from bright sun to complete darkness. For these reasons, thermal cameras have become the best choice for “seeing in […]
We’ve added narration to the SightLogix perimeter intrusion detection system overview, shown below. Each video panel displays the view from a visible, wide angle and thermal perimeter security camera, while the bottom right shows a PTZ camera automatically steered to zoom and follow detected targets. The target’s location is simultaneously displayed onto the topology map on […]
SightSurvey uses Google Maps to create a perimeter security design on any facility to address typical intrusion detection issues — like camera blind spots and terrain conditions — and determine vulnerabilities.
When it comes to protecting outdoor areas, security professionals often have two main concerns: Not being aware of the risks that are lurking, and not knowing the place and nature of an intrusion should one occur. Intelligent video cameras address the first concern by leveraging the inherent strengths of automated systems and people. Smart cameras […]
Outdoors, video analytic cameras have to “see” security violations against a background that is in constant movement. This means video analytic cameras must ignore movement from branches, trees, foliage, or reflections in water, while still sending an alarm for “important” motion caused by objects that traverse the camera’s field of view, like a person or vehicle.
Camera movement impacts outdoor video detection as a source of video analytic nuisance alarms. Without stabilization, video intrusion detection systems for rail security, airport perimeters, border security, seaports and other large outdoor facilities can be overwhelmed by nuisance alarms or misdetects.
The key to eliminating nuisance alarms for outdoor intelligent video is to use technology designed for outdoor applications rather than misapplying video analytics intended for more controlled indoor surroundings.
