Best Panoramic Surveillance Cameras for Commercial Security Systems

What is a Panoramic Surveillance Camera?

The most unfortunate fault of typical security cameras is blind spots. More often than not vital surveillance evidence is lost due to limited field-of-view from standard cameras. Though adding more cameras would technically solve the issue, that is not always an effective solution. It will bring about higher costs for installation, software licensing, and maintenance. A quality commercial security systems engineer will tell you that installing a fisheye or panoramic surveillance camera will solve this problem delivering less blind-spots and more situational awareness.A panoramic surveillance camera has several on-board sensors. Typical configurations can be a dual-sensor which is perfect for hallways in most commercial applications, the quad sensor best used indoors in large areas like auditoriums, gyms, or exterior corner mount of the buildings. Adjustable multi-sensor cameras can have each sensor pointed to a different direction and optical zoom ratio looking at different areas both near and far. This outline will deliver the benefits and drawbacks of the different breeds of panoramic surveillance cameras on the market today that are best used for commercial security systems.

Since the camera is a single-sensor with a ‘super’ wide-angle lens the camera distributes the sensor’s pixels over a wide-field-of-view.  This is often great for lower-ceiling mount applications but when trying to get forensic details at a large radius over 30 ft fisheye cameras will become more pixelated.  Know your security objectives before using fisheye cameras to cover large areas as they may be best served to be used as a situational awareness camera only and you won’t necessarily need 360 cameras everywhere.

What is fisheye Dewarping?

Dewarping refers to the process of viewpoint correction of an image after it has been captured by panoramic surveillance cameras. This means reversing the effects of geometric distortions caused by the camera lens captured by the panoramic surveillance camera. These distortions are caused by using fisheye and 360º camera surveillance devices. Dewarping allows the user to record a wide area with a single device, and to then convert that view of a considerably distorted image and revert it to a functional view. This technology is what ultimately puts the value behind fish eye and 360-degree surveillance cameras.

Multi-sensor Surveillance Cameras

Multi-sensor cameras are highly intelligent. Many of them are equipped with a wide range of video analytics. These include adaptive motion detection, camera sabotage, object or people counting, removed object detection, and a variety of other intelligence. All of these contribute to superior overall security by sending out alerts for any unusual or abnormal activity that may require further investigation. Multi-Sensor with PTZ Extension- These cameras traditionally only used outdoor combine the best of both works the ‘overview’ of the 4x panoramic sensors and the optical zoom of the PTZ that can get detail at long distances.

Dual-sensor Surveillance Camera

Though they are not as equipped with as many sensors as multi-sensor devices, dual-sensor video surveillance cameras still serve a great purpose. They provide high-quality footage, but do not have an overkill of capabilities and ultimately are very cost-effective. These cameras provide value through being placed in well lit interior areas and are effective most commonly in intersecting and L-shaped hallways as well as small lobbies. These cameras really come in handy for saving money while still acquiring surveillance for low traffic areas.

Something to keep in mind with these surveillance cameras is that they will not acquire surveillance right below the sensor, so it is optimal to choose locations for this device that will not have a future issue based on this lack of surveillance. That is why it is optimal to have a commercial security professional dictate where panoramic surveillance cameras would be best while also knowing when a dual-sensor camera will work just as well.

A Breakdown of Applications for Panoramic Surveillance Cameras

Typically mounted on indoor ceilings, panoramic surveillance cameras are a necessity for commercial facilities working best in high traffic or private indoor areas and parking garages. These cameras also work well mounted on walls in certain areas. It is best to place the cameras in wide-open areas and avoid corners so that you can harness the full effect of the fisheye capabilities. Along with that, it is important to use cameras with a high resolution and avoid areas with inconsistent light so that when you process the footage it will come out efficiently when dewarped.
