Using a thermal camera for outdoor sites has become the smart choice for protecting perimeters and facilities. Because thermal cameras see heat instead of reflected light, they are a great “human detector,” even in complete darkness. They ignore all the movement that triggers alerts with a visible detection camera, like headlights, reflections and direct sun. And they cover large areas more reliably than visible cameras.
Choose a Thermal Camera Engineered for Performance
But not all thermal cameras are the same. SightLogix has taken a different approach from other thermal security cameras, creating a high-performance, cost-effective system for protecting outdoor assets with low nuisance alerts and very few misdetects.
Compare the key features of the SightSensor, listed here, when considering a thermal camera for your site.
Powerful Thermal Camera Processing
SightSensors include powerful video processors inside the camera, which have access to the raw thermal video as it leaves the imager. This distinguishes the SightSensor from most other smart cameras, which use compressed video without high-performance processing. When video is compressed, it loses most of the scene details – up to 99% of the original data – seriously weakening the camera’s ability to detect and recognize targets.
With the SightSensor, 100% of the detail is available for video content analysis, improving detection accuracy and reducing unwanted alerts, even in bad conditions like heavy rain.
Longer-range Thermal Cameras Reduce Costs
The same video processing used for accurate detection also gives SightLogix cameras extended range and coverage, automatically detecting human-sized targets at ranges that can exceed 600 meters.
As a result, SightLogix systems reduce the number of cameras typically required for outdoor sites, often eliminating two out every three camera poles and their supporting infrastructure (trenching, networking, power, etc.), lowering overall project costs significantly.
Detect People, Not Distractions
Smart cameras are designed to detect movement, but outside, everything moves. Knowing the actual size of objects lets you create size rules to filter unwanted movement and increase accuracy.
When you install a SightSensor, a simple point-and-click-calibration calculates the true size of everything in the scene, creating a three-dimensional field of view. Which this information, the camera will ignore small animals, blowing debris, or moving foliage, while detecting human-sized intruders over very large areas with impressive accuracy.
For example, a small animal near the camera will look much larger than a man at 300 meters away, as you can see below.
Using SightSensor calibration, the video analytics knows to ignore the animal at right while alarming on the distant person on the left, even though the animal covers more of the camera’s field of view. The same approach applies to trash, clouds, and other movement which is always present outdoors.
Hands-Free PTZ Control
PTZ cameras play an important role in a perimeter system, providing an up-close view of a detected target along large perimeters. However, trying to manually steer a PTZ onto target can be like trying to find a needle in a haystack.
For this reason, SightSensors can be paired with SightTrackers to automatically direct pan-tilt-zoom (PTZ) cameras to zoom onto the exact location of an alarm in real time, making the target large enough to reliably identify, stop in real time and record for critical evidence.
Optimized, All-in-One Thermal Camera
SightSensor video analytics have been optimized for the specific imager used in our cameras. This removes all the tweaking and configuration that that’s needed when trying to match one manufacturer’s detection software to a different manufacturer’s imager. With all-in-one, edge-based SightSensors, such time and effort is unnecessary, saving deployment effort and ensuring a very high level of performance.
Stabilization Reduces Nuisance Alerts
Thermal cameras are often deployed along open areas that are naturally impacted by high winds or vibrations. It’s difficult for smart cameras to detect movement in a scene when the whole field of view is also moving from camera shake. Without image stabilization, these applications can be overwhelmed by nuisance alarms or worse, outright misdetects. For this reason, all SightSensors stabilize the video before analytic rules are applied, reducing nuisance alerts caused by camera motion.
