ROI, ROSI and Cost-Benefit of CCTV

There is a good discussion over at Schneier on Security about the value of London's surveillance cameras. It is useful to recognize the value proposition of detective measures - we don't expect to prevent malicious actions, we expect to increase the likelihood that the bad guys will get caught.

The value proposition of detective controls can be a bit trickier than it seems. From a Return on Security Investment (ROSI) perspective, the overall goal is to increase the costs associated with crimes and therefore:

1. Reduce the number of incidents that occur through a deterrent effect;
2. Increase the likelihood that bad guys will be identified;
3. Contribute to the body of evidence available for a crime; and
4. Shorten the time span of active investigation.

From a Return on Investment (ROI) perspective, the cameras may be much less expensive than alternative measures being considered (or replaced) for crime fighting.

Regardless of what side you are on, this is the right discussion to be having.

Clearly having surveillance cameras is a step in the right direction. People think twice when they know they are being observed. However, they also know that with thousands of hours of video feed, it will be hard to find them and their criminal act....enter new companies working on video intelligence which can sift thru all the video data and analyze it in real-time...making it much more effective in deterring criminal behavior.

I am satisfied with your blog.Thanks for sharing your precious comprehension with me relative to the advantages of surveillance camera in terms of road safety and also helpful in capturing the correct person who is involved in the accident cases.

Agree

Today's surveillance systems allows you to search much faster for recorded information first by very user friendly software second by not recording at times there is no motion...
