It doesn't really make sense to pay for expensive personnel that are authorized to write tickets, perform searches, and use deadly force to patrol your streets when the main benefit is mostly (a) the possibility of witnessing illegal activity while it's going on, and (b) a visible presence that dissuades potential criminals from their activities. Neither of these requires nearly the level of training or expertise.
I'm not sure what the exchange rate in terms of hours is where I'd rather have the police officer patrolling rather than a security dude, but we can get a handle on the relative cost. Indeed.com says security officers in San Francisco have an average salary of $35,000, and the starting pay for police in San Francisco is $89K-$112K. If you fully burden the security officer with benefits, and fully burden the police officer with their dramatically higher level of benefits and pension, it's not difficult to imagine that the security officer is 5-6x as cost effective. So would you rather have 12 hours of police patrols or 60 hours of security officer patrols?
I suspect there is a tipping point in terms of presence past which a neighborhood gets known by thoughtful criminals as being well-patrolled, which causes a significant decrease in crimes committed there.
And that's assuming there's no overheads to pay for like tax, health insurance, paid leave, pension contribution, social security, unemployment insurance, worker's comp, uniform, car, gun...
So I'd agree with your assessment that $8000 isn't very much.
Something doesn't add up here.
What's the research like?
VMA Security Group will only continue the patrol beyond February 2014 if 250 households have entered into contract at $20 per month, renewable and paid at six-month intervals. If we sign up 250 households at $20 per month for the four month trial period ($82.05 per household x 250 households = $20,513), that will put us in position to have service continuing beyond February 2014.
$5000/month (250 x $20) would be the monthly fee after February. 12 hrs x 5 days x 4 weeks = 240 hr/month, so that comes out to $20.80/hr gross salary.

I used the comments section of the article to further clarify some of my/our views on this topic if you're interested.
Also, in the article, the CEO of Crowdtilt implies that this is a net-positive because Oakland PD will be able spend more time patrolling other areas--implying that Rockridge will now get less police attention. If that's true, I wouldn't want to pay money for my neighborhood to get less real police patrol.
