Sussex Police are piloting a surveillance scheme which could revolutionise the way crimes are recorded amid criticisms the scheme could be an invasion of privacy.
The force has been using unmanned aircrafts systems or drones to fly over Gatwick airport so they can see exactly what is going on.
High-quality pictures are beamed back to officers using a portable console, up to 500 metres away.
Police say this allows them to quickly assess locations and film incidents from above.
They also believe it is more cost effective than the equivalent - filming incidents from a helicopter.
This is a three month pilot to see how it pans out. But obviously it has got to be able to fly in quite high winds. It has got to be able to fly in rain.
However, civil liberties groups questioned the "pressing need" for drones and argued there was already enough CCTV around Gatwick airport.
I want to know what the pressing need is for this drone. So is this an admission that the CCTV around Gatwick Airport - and I should imagine there are tens, if not hundreds - is that an admission they are not working? Are they going to be taken away and replaced with a drone? I think there needs to be a justifiable and pressing need, as the CCTV regulation says at the moment, and that hasn't really been spelt out.
