Police are appealing for witnesses after a pole was cut down and a speed camera stolen in Launceston.

The camera at Kings Meadows Link Road is believed to have been cut from a four-metre pole by someone using an angle grinder in the early hours of Saturday morning.

Passing drivers reported the theft about 5:00am.

Police have used social media to appeal for information.

"We know they are not the most popular addition to the state's infrastructure but ... this is beyond ridiculous," Sergeant Darren Turner said in a Facebook post.

"This would have taken planning and time (someone must have been really peeved at their infringement notice) and we're appealing for anyone who may have witnessed suspicious activity around the speed camera to contact us."

Sergeant Turner told ABC News it would have taken some time for the camera to be removed but if the motive was avoiding a speeding fine, it was a waste of time.

"It's instant upload, fortunately the hard drive is located in another area and so that material hasn't been taken," he said.

"Entry had to be forced to the box area that sits at the top of the pole and then they had to unplug several items to remove the camera and lens."

The culprits also tried to tackle a second camera.

"They've also entered another box, it's situated at that location and stole four batteries, four large batteries, each one of those weighed about 25 kilograms so the offenders would have been there for some time."

Police estimate the value of the equipment at several thousand dollars.
