Let's agree that we are only including businesses here, not residential / home use (which obviously would skew numbers down given they frequently have 1 or 2).
Here's our stats from the integrator Winter 2014 survey:
Average then around ~20, which is consistent with what we surveyed 3 years ago. Numbers from SSI are published periodically and I believe their average is 14 to 16, which is lower likely do to their readership based being more intrusion / smaller video dealers.
So those 2 metrics provided to you are very likely to be wrong.
Also, the number is even higher if one looks at the mean rather than the median, as installs with 1000s of cameras would skew the number notably higher.
One other big factor is whether one wants a mean or median figure.
Given that camera systems range from 1 to tens of thousands of cameras, the mean is going to be much higher than the median.
For example, let's say we had these set of camera systems: 1, 4, 6, 9, 16, 24, 60, 100, 1000 cameras
The median would be 16 (i.e. 5th of the 9 in the list).
The mean would be 149 ((1+4+6+9+24+60+100+1000)/9).
Now, I don't think it's this skewed, in practice, but surely the mean is integer multiples more than the median.
If I cared about total revenue, I'd be much more interested in the mean than the median. Conversely, if I wanted to know what is most common walking into a random building, I'd take the median over the mean.
John, I am guessing the respondents of your survey were larger integrators rather than small installers. Based on our experience of working with a very broad spectrum of integrators/installers/dealers the overwhelming number of projects are less than 16 cameras even after netting out consumers. And we don't sell any low-end analog systems.
Rukmini, thanks for reminding me why statistics gave me the hives in college.
It depends on what your core business is. I have been with a company where the average had to be around 20-40 and with companies where the average was probably between 3-6. When I was a rep, the average was probably between 20-40.
In fact, a main camera manufacturer direct rep once told me that he only gets involved with projects that are 50 or more cameras.
The difference is probably contract work and refurb work versus service work and Small and Medium Business work.
Reading comments and seeing various polls in this site, I expect the majority of people here work with more Small to Medium Businesses. Something you should probably take into consideration is the sites poll figures will be skewed more that direction and may not be the true representative of the national or global average. It is the site average. So if your're a contractor, the numbers may not seem right to you and seem pretty low.
Update - Wow, the IPVM average has gone up since 2011 I beleive. Those #'s seems a lot higher. - Stil I note that forum commenters seem to be for small to medium business.

We have a bit more than 5000 cameras delpoyed in the field that we monitor, maintain, etc... Job average is almost exactly 10 per, at about 90% IP. With that said I want to sell for the 14% installing 65 or more.
Are there other useful metrics of complexity? Number of users viewing video perhaps? fully stand-alone vs. integrated with existing infrastructure?
The manufacuring industry usually produces these figures and uses the "averages" to set price points and sales strategies and drive the manufacturing and technology decisions at the recording side. As a consultant and former sales/sales manager I know the response to the question you pose depends greatly upon two contributing factors: the installer (large integrator vs. local dealer) and the industry served by them. I know of system integrators that market almost exclusively to the USG defense industry who won't even bother to participate in small system projects and other dealers that are only comfortable with small, fast turnaround projects such as light commercial, retail, etc..
Though the total averge number of cameras per recipient might be useful in some way to a professional consultant, I'd like to see more granular informatiomn that added the industry sector addressed. For instance it would be helpful to know the average camera install for rail transportation projects vs. high-rise commercial real estate, vs. USG non-defense, etc. These stats would have more value to both the dealer an the consultant who wishes to target their marketing efforts.
As for averages for my own trade I couldn't even begin to estimate. I led a design/build team that recently installed over 1500 cameras, designed for at least one untra high net worth residence that included the install of 68 cameras, and did a small retrofit for a huge transportation authority that averaged 4 cameras at each of four facilities (added to the 30+ cameras per site existing).
Just food for thought.
