A wide angle security camera (180-degree security camera) can be used for indoor and outdoor video surveillance systems because the housing is weatherproof. The 2.5mm fisheye lens captures a 180-degree field of view (170-degree effective range).
A wide angle surveillance camera can provide a complete overview of small to medium-sized rooms . The 180 degree / ultra wide angle view and the fact that the cameras are IP66 weatherproof rated also make it a great choice to monitor exterior entrances at very close quarters. They can capture video in normal, low light and zero light conditions. The tri-axis bracket on some cameras allows installers to ceiling mount or wall mount the camera and angle the lens in any direction.
They are typically connected to a surveillance DVR by hard wiring it using the same RG-59 or RG6 coaxial cable that is used for analog CCTV cameras.
