When it comes to video surveillance, lighting is one of the most important factors in image quality. As lighting conditions fade and shift depending on the time of day and environmental factors, a surveillance camera’s ability to capture evidentiary detail can decrease.
At Avigilon, we've developed two new surveillance camera solutions that can address and overcome challenging lighting environments: the H4 IR PTZ (infrared pan-tilt-zoom) and H4 Thermal camera lines.
Infrared Imaging Lights Up The Night
To overcome the darkness of a scene, artificial sources of light can be integrated with a camera, the most common of which is infrared (IR) illumination.
For example, total darkness is no match for our newly launched H4 IR PTZ camera line (watch video), which combines a powerful 45x zoom lens and zoomable IR technology to detect objects up to 250 m (820 ft.) away. The camera's IR projection angle and distance automatically adjust based on camera zoom lens movement, ensuring the scene is illuminated consistently across the field of view for high-quality, detailed images.
Between the camera's IR technology and a zoom lens that can clearly capture an image more than two football fields away, the H4 IR PTZ is your key to conquering the dark in environments such as perimeter fence lines, airports, and commercial properties.
Thermal Imaging Glows In The Dark
Thermal imaging is all about detecting the different heat signatures that people and objects emit. Thermal cameras detect these heat signatures and displays them as shades of grey.
Our H4 Thermal camera line (watch video) operates beyond the visible spectrum. It has been designed to detect the movement of people and vehicles even in areas with poor visibility, challenging lighting conditions, absolute darkness, and partly camouflaged objects.
In addition, the camera utilizes patented Avigilon self-learning video analytics to send notifications to operators when it detects an activity that may require further investigation, helping you take decisive action when it's needed most.
The H4 Thermal camera lets you cover long distances with fewer cameras. Through this, you can reduce the total cost of ownership across your installation. Its bullet-style, all-environment design is outdoor-ready and well-suited for a wide range of applications. Unhindered by environmental factors and able to detect subjects of interests through a various levels of visibility, it can help you light the way forward for your surveillance needs. Whether outside a storage facility and exposed to the elements or in a parking lot setting with variable lighting conditions, the H4 Thermal can cut through the darkness to let you see what needs to be seen.
Together, these two Avigilon cameras work to offer an all-season, all lighting surveillance solution. They can even work in tandem: The H4 Thermal provides excellent detection of objects, which in turn can alert operators to zoom in and investigate with further detail using the H4 IR PTZ. Truly, a match that conquers the dark.
