Exactly about CCTV Cameras In addition to their Functionalities
Access Control - There exists a growing interest in CCTV camera installations both in commercial and residential security needs. These cameras work either separately or in combinations with other security solutions like access control or intruder alarm. With the analog camera systems becoming outmoded, consumers find CCTV systems your best option for their security needs. However, both individuals and businesses find it confusing when it comes to choosing the proper selection for their security needs.
The differing types of CCTV Cameras
There are various types, configurations and designs of CCTV cameras available, giving a wide range to pick from, based on their intended applications and needs.
Dome Camera
Security Systems - The most typical type is the Dome Cameras found in indoor security and surveillance applications. The shape of the type causes it to be hard to be aware of direction of facing of these cameras and it is ideal to prevent criminals in their nefarious plans. The recognition also stems from three good reasons, namely:
Easy installation - there's two or three screws required to install most of the dome types. Also, these cameras can be mounted easily on both horizontal and vertical surfaces like walls and ceilings.
Vandal-proof feature: The hardened plastic casing since the camera protects it from vandalism.
Infrared Capability: there are several dome cameras who have IR illuminators, which makes it an easy task to capture video images in low lighting conditions.
Bullet Camera
These cameras have long, tapered, and cylindrical shape as present in a "rifle bullet", passing on the name. They're used for outdoor applications, where there is really a dependence on long distance viewing. These cameras are installed inside protective casings, protecting them against dirt, rain, hail, dust and other harmful elements. There's a mounting bracket that helps to point the digital camera in a desired direction. These cameras are fitted with either fixe or varifocal lenses.
C-mount camera
Access Control - These have detachable lenses that enable users to alter lenses in line with the demand for the applications. For instance, the typical CCTV camera lenses are able to keep a watch between 35 and 40 ft distance, while a C-mount camera using special lenses can cover distances further than that.
Day/Night Camera
These types can be employed in both normal and faintly-lit environments. Since these cameras have an extra sensitive imaging chip competent to capture clear video images in the dark, you don't have for inbuilt infrared illuminators. This will make this camera an ideal selection for outdoor surveillance applications, where IR cameras don't function optimally.
