According to this artice in Independent the half of cctv systems do not reduce crime.
There are more than 4 millions CCTV cameras installed, but CCTV failed in crime fighting.
Why CCTV is so Inefficient?
- Many cameras are placed at wrong locations. Some are too height, some have too narrow or too wide angle of view so targets. CCTV installers just do not use a 3D CCTV modeling software to find optimal camera locations.
- Resolution of many cameras is just too low.
- You cannot find a security personnel ready to watch multiple cameras 24/7. Actually the software should take the boring part of video monitoring and attract the human attention to recognise dangerous situations only.
- Sometimes the length of the video archive storage space is just too short. To prevent this the system designer must do CCTV storage estimation to choose a proper disk volume.
Wrongly made CCTV systems are just wasted money. Sometimes the taxpayers money.
