Exactly about CCTV Cameras And Their Functionalities

[http://www.securitydirect.ie/blog/ Home Alarms] - There exists a growing demand for CCTV camera installations both in commercial and residential security needs. These cameras work either separately or even in combinations along with other security solutions like access control or intruder alarm. Using the analog camera systems becoming outmoded, consumers find CCTV systems the best option for security needs. However, both of these people and businesses find it confusing with regards to choosing the proper choice for their security needs.

The different sorts of CCTV Cameras

There are different types, configurations and fashoins of CCTV cameras available, giving a wide range from which to choose, based on their intended applications and requirements.

Dome Camera

[http://www.securitydirect.ie/blog/ Home Alarms] - The most common type may be the Dome Cameras seen in indoor security and surveillance applications. The design of the type can make it challenging to be aware of direction of facing of such cameras and it is ideal to prevent criminals within their nefarious plans. The popularity also stems from three reasons, namely:

Easy installation - there are 2 or three screws needed to install most 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 covering the camera protects it from vandalism.

Infrared Capability: there are several dome cameras who have IR illuminators, making it an easy task to capture video images in low lighting conditions.

Bullet Camera

These cameras have long, tapered, and cylindrical shape as found in a "rifle bullet", passing on the name. They are 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 is a mounting bracket that helps to point out the camera in the desired direction. These cameras are fitted with either fixe or varifocal lenses.

C-mount camera

[http://www.securitydirect.ie/blog/ Home Alarms] - These have detachable lenses that permit users to change lenses in line with the demand for the applications. For example, the conventional CCTV lenses can keep an eye 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 be employed in both normal and faintly-lit environments. Since these cameras have an extra sensitive imaging chip qualified to capture clear video images at night, you don't have for inbuilt infrared illuminators. This will make this camera a great option for outdoor surveillance applications, where IR cameras usually do not function optimally.
