BULLET CAMERA: 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 fixed or varifocal lenses depending on the requirement. • IR night vision. • Compact size aids installation. • High-quality image resolution. 3. C-MOUNT CAMERA: Coming with detachable lenses. C-mount cameras allow for simple lens changes to fit different 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. Other benefits of C-mount cameras include: • Can support charges in technology • Effective for indoor use • Bulky size makes them noticeable (which acts as a deterrent) 4. 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 idea for outdoor surveillance applications in which IR cameras are unable to function optimally. Other benefits of day/night cameras include: • Record in both colour and black & white. • Wide variety of sizes available • Infrared capability. 5. PTZ PAN TILT & ZOOM CAMERA: allow the camera to be moved left or right (panning), up and down (tilting) and even allow the lens to be zoomed close or farther. These cameras are used in situations where a live guard or surveillance specialist is there operating the security system. Other benefits of PTZ Cameras include: • 200M IR night vision. • X36 optical zoom. • High-quality image resolution. OTHER TYPES OF CAMERALS 1. DARK FIGHTER TECHNOLOGY CAMERA: These cameras can pick up coloured images in very low-light conditions. Dark fighter technology can be used in the day and night and offer optimal performance thanks to its wide range of capacities. They are equipped with ½ CMOS progressive scan sensors which allows the device to pick up high-quality images and doesn’t require an extra light source – which makes the perfect night time security surveillance Other benefits of Dark fighter technology cameras include: • Smart features: line crossing, audio and face detection • Can be used for a multitude of purpose • High definition. 2. ANRP/LPT CAMERA: These cameras are used to read and store data on registration plates, They offer a simple and efficient solution to many organizations including tolling hotel overstay management and the obvious: car parking AMRP stands for AUTOMATED NUMBER PLATE RECOGNITION (LPR Cameras stand for license plate cameras) and these devices help to certain copious information in a high traffic area to keep any premises secure. Other benefits of ANPR/LPR cameras include: • Smart features information storage. • Can identify cars that have been banned from premises. • Allows a business to run smoothly without your presents. 3.

THERMAL IMAGE / INRARED 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 the day is. Infrared cameras have small LEDs surrounding the lens to helps pitch black. Terminals images cameras can see over distances, up to 300 meters away. Other benefits of infrared cameras include: • Detect intrudes up to 250-300 meters away. • Good in low-light. • Terminals radiation passes trough visual barriers 5. 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 with any alternative , fixed lens camera Other benefits of varifocal cameras include: • Can capture those ‘dead zones’ that other cameras can’t. • Offer exceptional focus. • Work well up close and at long distance. 6.

THREE FACTORS NEEDED TO CONSIDERED BEFORE CHOOSEN CAMERAS 1. The correct Lenses: This will ensure you receive a quality image. Choosing the right lens will allow your camera to focus and will bring enough light to the sensor on the camera. Helping you to read registration plates and recognize faces etc. Having more details will of course help in all situation, because it means that you will be able to see exactly what is happening and get a clear record on film. Zoom lenses can provide customers with more information because optical zoom can adjust the light as it reaches the sensor, enabling flexibility and enhanced pictures. 2. The correct sensor: There are two things to take note when finding the right sensor: the type and size. • CMOS (Complementary metal oxide semiconductor) CMOS cameras produce clearer images, also ideal for identifying faces and registration plates. • CCD (Charged coupled device) cameras, they are more expensive than CMOS. 3. The correct output resolution: The more pixels, the better the picture. The highest resolution you can get is 700TVL but many mainstream cameras range between 300-550TVL, It is important to match a resolution that your cameras can produce, anything more is completely
unnecessary.
