Russia's capital has a network of 146,000 cameras to watch city streets and ensure that residents, visitors and businesses are behaving.

The cameras are used to verify that trash has been picked up, crackdown on speeding and red-light running, monitor snow removal and be certain that on-street advertising is legal.

The government is currently upgrading the cameras intelligence to better analyze footage. For example, the cameras could one day identify when a person doesn't clean up after their pet. If a dog leaves droppings, an owner may potentially receive a ticket in the mail.

While every city may not follow Moscow's lead, the city is showing what technology makes possible.
