People who own a drone with a camera attached could be fined £1,000 if they don’t register their device.
The new regulations, introduced on New Year’s Eve, were designed to protect the privacy of citizens.
Devices will have to be registered to the UK Civil Aviation Authority (CAA) or the owner will risk a penalty.
Previously all drones heavier than 250g had to be registered but this now extends to lighter ones that have cameras.
The regulations came into force in the UK ahead of Europe adopting the measures on Friday.
The rules are expected to increase the number of drone users after the distinction between recreational and commercial applications was removed.
The regulations group drones into risk categories of high, medium and low, with all required to be registered with the CAA.
Low-risk drones will have operational limitations but will not need authorisation for flights.
Authorisation will be needed for medium-risk drones depending on a risk assessment, while high-risk craft will have to observe aviation rules.
The guidance mirrors that of the European Union Aviation Safety Agency, which from 1 January will unite drone rules across the EU, Norway and Iceland.
Drone owners need to complete a test online before being permitted to fly a drone.
They must also display an ID number on their device.
CAA memberships cost £9 annually.
