CCTV Surveillance Cameras are fast becoming common place. They are now installed in homes, shops, businesses and office, acting as a deterrent to crimes as well as helping home and business owners keep an eye on what is happening in their absence.
The use of CCTV Cameras in the home has extended beyond mere protection, to include remote supervision and monitoring of domestic helpers, young children as well as elderly relatives. CCTV Cameras installed in the shops, while serves as a good deterrent to shoplifting, has been used to help management supervise and manage customer service standards.
Now you can watch your premises using your laptop, your mobile phones or tabs, wherever you are, whenever you wish. Security and convenience at your finger tips.
CCTV Cameras used to be either analogue or digital.
An analogue camera captures an image, encode it and transmit the picture to the video recorder using voltage. This voltage signal is decoded at the recorder and the image is stored on a hard disk. A digital camera captures an image, encode it and transmit the data to a network video recorder where the digital image is stored on a hard disk.
The difference between an analogue and a digital cameras lies in resolution, sharpness, image size and the ability to zoom in and yet maintain sharpness and clarity. There is also a drastic difference in the cost of an analogue versus a digital camera and the complexity and technical knowledge to maintain the system. And for a time, both are really at the two side of the spectrum. While advances in manufacturing have lowered the cost of a digital camera, the analogue camera became even cheaper.
In recent months, there is a break through in technology and a new type of CCTV System was launched - the HD Analogue Camera. These are analogue cameras that looks and works like analogue cameras and can use the existing analogue cabling infra-structure yet deliver High Definition images that are quite comparable to the digital camera.
Like digital cameras, the HD cameras can transfer full HD (1920 x 1080) over coaxial or any twisted pair baluun up to 1000m. It bridges the gap between analogue and digital, at a price just a little higher than analogue cameras.
