I am looking for standards or research in which I can find info on how many camera's a operator can monitor effectively and for how many hours monitor in a city surveillance system.
any suggestions or links?

City Surveillance Standards For Monitoring Effectively?

I am sure you already know, but for others, the trend now is to shift to more 'smart' or 'event' driven monitoring as most cities recognize that is not really feasible to monitor video feeds directly at the scale they have.

Mar 03, 2018I agreed with your comment.... but is scale the only issue?
i.e. are video monitoring companies who provide this service for companies (vs cities) still using humans to watch screens, or, have even the smaller providers also gone to analytics/event-driven alerting vs humans watching screens?
imo, humans watching screens is akin to unmanned PTZ patterns covering large parking lots; both were technologies used only because better technology didn't exist at the time it started being used.
Now we have the resolution needed to cover larger areas with a fixed camera (i.e. 4k/10MP for instance) that covers/records the entire area instead of just where the unmanned PTZ is looking at any given time in it's pattern.
As analytics-based alerting matures, I see a diminishing value proposition for any company offering to 'watch screens' as a service. (WSaaS)

Mar 03, 2018In the US I'm noticing that city surveillance is not a matter of monitoring, but having enough coverage for evidence after an incident.
It is not feasible to monitor hundreds of cameras in real time

Mar 03, 2018I do agree with all of you, issue is that locally we are 10 years behind the developments as are on going in the US/ Europe and Asia. beside that there is a huge unemployment rate, next to a very high crime rate and a very bad financial situation of the government. currently they are deploying a system, although I am not sure if it will really work. (there are not even laws in regards to video surveillance and the use of it in court. so we need to do it step by step. if it will be too advanced it will probably not even start.

Mar 03, 2018What type of system are they deploying and what type of system would you propose?
geert Huisman
Mar 04, 2018it iis a system delivered by inspur (chinese company) with Dahua camera's
I would go more for a system in which you can integrate with private camera's. to get a maximum coverage. options would be mile stone although I do not have experience with it. it is not designed yet. but I am looking more for standards to build a business case. for ea the system in NYC, but maybe there are better alternatives.
so any one with experience with these systems I am open for suggestions etc. never too old to learn an specially nt from people with real experience in this field. unfortunate most projects are low scale and a little bit old school in our region...

Mar 04, 2018In the US, you should research Real Time Crime Centers. All major cities have them and most are doing the same thing. Using Milestone or Genetec as thier VMS.
When you look at NY, Chicago and these other larger cities, they are not cheap. Chicago spent over $100m. I would look into what smaller cities are doing because of your cities budget constraints
Here is an example of a smaller city using Milestone in thier Real Time Crime Center:
City of Hartford Expands Safety With Ongoing Innovations
How many cameras would you propose?
How do envision connecting to private cameras?

Mar 04, 2018Paul,
many thanks. I will check it. the amount is not yet determined. because of the budget issues, i would look for a solution in which private camera's can be connected. e.a using the 2nd or 3rd stream. only we have to go discuss with the ISP's because of up and download speed restraints
In holland they have a system called live view. when a duress button is pressed the images are being received at private monitoring station. in case of a real event the mages are being sent to the police monitoring station.

Mar 04, 2018I've seen private cameras being connected via PSIM solutions
These are generally llimited by the type of VMS the entity is using.
A larger city here in the US was requiring the businesses to use Milestone to connect to their RTCC that is running Milestone as well. It proved too expensive and difficult for the businesses, so they scrapped that idea.
The bigger hurdle is most SMBs are using cheap Chinese brands such as HIkvision, Dahua OEMs or even Nest and Arlo. They are not able to connect to these types of systems, especially at scale.
