CCTV & SURVEILLANCE

CCTV plays a huge part in today’s society, and with cameras all around us, our day-to-day lives are experiencing higher levels of security each day. What many people don’t know, however, is that there are a variety of different types of CCTV camera which suit different situations or premises, and that selecting the proper camera for the right application really is vital.

TYPES OF CCTV

Here, we run through these types of camera and what makes them unique and more suitable for some venues over others.

Internal and External Dome Camera

The dome camera is one most commonly used for indoor and outdoor security and surveillance. The shape of the camera makes it difficult for onlookers to tell which way the camera is facing, which is a strong piece of design, deterring criminals by creating an air of uncertainty.

Bullet Camera

Bullet cameras are long and cylindrical in shape and are ideal for outdoor use. Their strengths lie specifically in applications which require long distance viewing. Installed within protective casings, the cameras are shielded against dust, dirt and other natural elements. The cameras can easily be mounted with a mounting bracket, and come fitted with either fixed or varifocal lenses depending on the requirements of its intended application.

C-mount Camera

Coming with detachable lenses, C-mount cameras allow for simple lens changes to fit different applications. C-mount cameras can cover distances beyond 40 ft thanks to the possibility to use special lenses with these cameras, whereas standard CCTV lenses can only cover distances of 35-40 ft.

Day/Night Camera

Capable of operating in both normal and poorly lit environments, these cameras benefit from not requiring inbuilt infrared illuminators as they can capture clear video images in the dark thanks to their extra sensitive imaging chips. For this reason, these cameras are ideal for outdoor surveillance applications in which IR cameras are unable to function optimally.

PTZ Pan Tilt & Zoom Camera

PTZ – Pan/tilt/zoom – cameras allow the camera to be moved left or right (panning), up and down (tilting) and even allow the lens to be zoomed closer or farther. These cameras are used in situations where a live guard or surveillance specialist is there operating the security systems.

Thermal Image Cameras/Infrared Cameras

One of the best 24 hour surveillance cameras around providing airports, seaports, boards and many other critical infrastructures with quality images, no matter what time of day it is. Infrared cameras have small LEDs surrounding the lens to help pick up moving figures in pitch black. Thermal image cameras can see over long distances, up to 300 metres away!

Varifocal Cameras

With the ability to zoom in and out without forfeiting its focus. Varifocal cameras allow you to adjust the focal length, the angle and increase or decrease the zoom – ideal for obtaining footage in a square room where you would normally experience a ‘dead zone’ with any alternative, fixed lense camera.

Network Cameras

These cameras share the images across the internet, so CCTV footage can be easily accessed. Network cameras are ideal for both domestic and commercial purposes because you can see what’s going on whilst away from the property.
