Problems to solve:

• Security is expensive
• Many receptionists are bored
• Security guards gets bored

Solution – for video security:

Bored people, like some receptionists, or someone on the train, get to watch security cameras for a short time, say 30 seconds on average, but you never know how long.

There are buttons they can push at the end of the viewing – nothing happened, maybe suspicious or alert. You have just a moment to click on one, it proves you were paying attention.

The same security feed gets seen by multiple people, and if two or more click an alert button, it is considered genuine.

In-between videos there are tasks to perform like Mechanical Turk. That keeps people awake and focussed.

Paid by the minute. Stop start whenever you want.
