In video surveillance, traditional cameras like PTZ and fixed cameras have one intrinsic flaw: the blind spot. If you fix a camera with its field of view towards right, and an incident occurs on left, the images recorded will do you no good. A good way to solve this problem is to double or even triple the number of cameras. This solution is far from optimal, bringing higher costs for installation, software licensing and maintenance. And mounting two or three times the amount of cameras raises aesthetic issues as well. A discreet 360º fisheye camera can eliminate these issues, and provide a perfect solution in any video security environment.
Here are 4 key applications of a 360º fisheye CCTV camera in video security:
1. In large areas: cover wide open spaces from one single spot.
360º fisheye CCTV cameras are designed to cover everything from a single spot. When mounted on a ceiling, it provides a full 360º view and can capture video images from every angle. Another option is to mount several 180 º view cameras to cover the area from side to side. However, make sure that the cameras are always mounted in a central location and not in a corner. When mounted in a corner, the effective coverage of a fisheye CCTV camera is reduced dramatically. A 360º fisheye CCTV camera can be applied to cover areas like large retail halls and assembly lines. 180º cameras are more suitable to cover parking lots, stairwells, hallways, checkout counters and other wide, straight lined areas.
2. The fisheye advantage for marine vessels
Marine vessels are usually gigantic and complex ships consisting out of many different compartments and various areas. Any event that occurs on board has to be attended to instantaneously in order to prevent possible hazardous outcomes. Video surveillance is therefore essential on board of these vessels. To ensure faultless video surveillance, mounted and PTZ cameras are mounted in each corner, offering only limited view of an area. Multiple cameras need to be installed in every room, cabin or chamber to ensure full coverage. On contrast to this, a wide-angle fisheye CCTV camera ensures a full coverage of the area, using up much less of the valuable space at the same time. The on board operations manager can cover a much larger amount of areas with half or even one third of the amount of cameras normally used.
3. Supporting healthcare surveillance
The use of traditionally mounted video security cameras might not be able to cover each corridor, hallway or room of a hospital. This poses threat to the well-being of patients as well as staffs. The use of 360º fisheye CCTV cameras can provide a solution to this problem. With its dewarped monitoring output, security managers can get a detailed view of almost every area of the healthcare premises. The wide-angle view of the cameras helps to reduce the cost of initial investment. With no event gone unnoticed, video security in healthcare helps improve the safety of patients and staff dramatically.
4. Perfect for use in public transportation
Transportation assets and facilities such as subway and train stations, airports and traffic junctions require effective and efficient video surveillance. These locations have spacious, wide-open areas that need coverage from every angle. A 360º fisheye CCTV camera can efficiently help minimize the number of devices required to get a proper view of each area.
Few of do’s and don’ts for the best application of a 360º fisheye CCTV camera:
+ Make sure it is placed in the center of a wide-open area, such as warehouses, large halls or corridors.
+ Use cameras with the highest resolution for the best effect when dewarped.
– Do not mount fisheye cameras in a corner. This reduces its effectiveness.
– Do not use a fisheye camera in areas with a high variety of light. This has a negative effect on the output image.
