Around 30 reports of dashcam and satnav thefts have been reported in less than six weeks in Ramsgate.
Three arrests have been made in connection with the thefts, and one man was charged and appeared in court.
Patrols are being carried out in the town and investigations into the stolen items are ongoing.
Police are now reminding vehicle owners in Ramsgate not to leave technology on display in their cars.
Inspector Rhiannan Pepper, from Thanet Community Safety Unit, said: "In many of these reports, windows have been smashed during the thefts, as items can be taken very quickly that way.
"Although people are mindful not to leave their wallet and purses on display in their cars, technology used in the car daily can sometimes be forgotten about – even though these items can be very expensive.
"Don’t give thieves a chance to go window shopping by leaving your valuable gadgets on display in your car. Take them out at the end of your journey.
"Try not to leave any clues that you use such equipment, clean the tell-tale suction marks from your windows and remove the holder.
"Also consider property-marking your dashcams and satnavs and make a note of serial numbers, so if they are stolen, it will be harder for criminals to sell on, and if we recover stolen goods, it will be easier to reunite you with your lost items."
