About CCTV Cameras And Their Functionalities

[http://www.securitydirect.ie/blog/ Security Systems] - There's a growing need for CCTV camera installations in the commercial and residential security needs. These cameras work either separately or even in combinations with other security solutions like access control or intruder alarm. With the analog camera systems becoming outmoded, consumers find CCTV systems the best choice for his or her security needs. However, both of these people and businesses think it is confusing when it comes to choosing the proper choice for their security needs.

The differing types of CCTV Cameras

There are different types, configurations and designs of CCTV cameras available, giving a variety from which to choose, according to their intended applications and requirements.

Dome Camera

[http://www.securitydirect.ie/keypads/ Home Alarms] - The most common type will be the Dome Cameras seen in indoor security and surveillance applications. The form with this type can make it challenging to know the direction of facing of those cameras and is ideal to stop criminals in their nefarious plans. The recognition also stems from three good reasons, namely:

Easy installation - there are two or three screws required to install a lot of the dome types. Also, these cameras could be mounted easily on both vertical and horizontal surfaces like walls and ceilings.

Vandal-proof feature: The hardened plastic casing within the camera protects it from vandalism.

Infrared Capability: there are some dome cameras who have IR illuminators, which makes it simple to capture video images in low lighting conditions.

Bullet Camera

These cameras have long, tapered, and cylindrical shape as present in a "rifle bullet", giving it the name. They're employed for outdoor applications, and then there is a need for long-distance viewing. These cameras are installed inside protective casings, protecting them against dirt, rain, hail, dust as well as other harmful elements. There exists a mounting bracket that assists to point out your camera in a desired direction. These cameras are fitted with either fixe or varifocal lenses.

C-mount camera

[http://www.securitydirect.ie/keypads/ Access Control] - These have detachable lenses that enable users to improve lenses according to the demand for the applications. For instance, the typical CCTV digital slr lenses will 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 kinds can work in both normal and faintly-lit environments. Since these cameras have an extra sensitive imaging chip qualified to capture clear video images at night, there's no need for inbuilt infrared illuminators. This makes this camera a perfect selection for outdoor surveillance applications, where IR cameras don't function optimally.
