Its a usual view to see CCTV cameras every area that we went to but nowadays,with a new technology, the CCTV also undergo a changes on its function and appearance. My observation in East Coast Mall has result me with this problem :
PROBLEM STATEMENT:
Can only record straight to a video tape recorder which are able to record analogue signals as pictures. If the analogue signals are recorded to tape, then the tape must run at a very slow speed in order to operate continuously.
· In one second, the camera scene can change dramatically.
· Has a very low speed in capturing images.
· If the targets are few meters away, they are invariably looks like a blur, unless the subject keeps relatively still.
· It is cheap, but inevitably the resulting in compression of digital signals.
SOLUTION TO THE PROBLEM:
Replace the analogue type CCTV with the digital type because :
- These cameras do not require a video capture card because they work using a digital signal which can be saved directly to a computer which is more energy save.
- The video quality is adjustable.
- Have a very high quality video and lead to a very good performance.
- It has a higher pixels resolutions which gives better images.
- Provide a higher security level to the surrounding areas.
