Fines have been dished out to fly-tippers caught on covert cameras installed at recycling sites in Torfaen.
So far 54 incidents have been caught on cameras installed by Torfaen County Borough Council with 14 culprits being landed with £75 fines.
A further 20 warnings have been issued and 24 cases are still being investigated.
The local authority introduced the cameras at recycling bank sites earlier this year, along with new signage about how to use the facilities properly, in a bid to combat fly-tipping.
Operations will continue and overt cameras will also be installed shortly.
Councillor John Cunningham, Executive Member for Operational Services, said: "The cameras have been a massive success and we will continue to use them both covertly and overtly.
"There is no excuse for dumping rubbish. Fly-tipping blights local communities and we will do everything in our power to deter it.
"Thankfully, it is only a minority of people who dump rubbish and we want to remind them that even if recycling banks are full or not available they must not leave their rubbish on the ground.
"The Council would like to thank the vast majority of residents for disposing of waste appropriately."
Cameras are also being used to catch vandals who have also been targeting the sites.
Hidden cameras are also used at other fly-tipping hot spots in the County Borough.
The maximum fine for domestic fly tipping is £5,000. Anyone caught fly tipping commercial waste could be fined up to £50,000 or face a maximum five year prison sentence.
Recycling banks are located at various locations in Torfaen including Cwmbran Stadium and Abersychan Car Park.
Materials that can be recycled at the sites vary but they include glass, plastic bottles, newspapers, tins and cans and Tetra Pak drinks cartons.
The local authority is currently the best recycling authority in South Wales- recycling 42 per cent of its waste.
