SSI Magazine about CCTV design topics

In recent Tech Talk column of Security Sales and Integration magazine there was an interesting article about critical CCTV surveillance design considerations.



Topics covered: Image resolution, Camera position, Lighting, Image detail, Maintenance and last but not least replaying usable images.

Why CCTV Is so Inefficient?

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.

CCTV Design for CCTV Designer

I want to write a short post about a small nice software for network video and CCTV designers.

It is called CCTV Design Tool. What I like there is a posiiblity to calculate CCTV Coverage.

This screenshots is self explaining.

For thouse who needs to design network video you can use CCTV Bandwidth and CCTV Storage calculations.

CCTV Tools - Must have tools for CCTV installer

Here is a list of my CCTV Tools:

1. Screwdriver set
2. Twisted pair cable cutter and stripper
3. Coaxial cable cutter
4. Special CCTV Lens calculator software from JVSG.com 
5. Voltmeter
   

Later I am going to explain why
