This is a good idea and question. Thanks for sharing.
I have not seen one developed by an end user like this but there are some lessons or takeaways that can be applied from manufacturer case studies.
Aspects to Quantify:
- Number of arrests and or convictions where campus video surveillance was used as evidence
- Number of incidents or citations where real time video or recorded clips were used as evidence to support reports
- Increase in guard, operator or investigator efficiency due to advances in technology speeding up searches or eliminating dispatching personnel to locations.
- Decreases in annual maintenance costs due to remote troubleshooting, lower camera count of higher resolution cameras, etc.
Then there are the more questionable / aggressive use of statistics, e.g.:
- Bike thefts have decreased by 62% since the new surveillance system was installed.
- Rapes are down 75% year over year
- Etc., etc.
I am not a fan of such tactics as they imply, with typically questionable connection, causation.
Hopefully others have recommendations and examples to share.
Mark, can you clarify what you mean by quantify effectiveness?
Do you mean in comparison to something?
- As it could be?
- No system?
- The previous system?
- Last years system?
