Police have released an image showing residents what to look out for if they think their property is being targeted by burglars.
Many burglars will mark either a gate or a wall to show other criminals, which houses are worth breaking into or stealing from.
The image posted on Twitter (below) gives a breakdown of the most common signs to look out for.
These markings are usually very small and most of the time not easily seen if you don't know what you are looking for.
Lock your doors and windows every time you leave the house, even when you're just out in the garden, remembering to double-lock UPVC doors (lift handle and turn key).
Hide all keys, including car keys, out of sight and away from the letterbox (remember a device could be used to hook keys through the letterbox).
Install a visual burglar alarm (as part of a suite of prevention measures - a burglar alarm on its own will not prevent entry to your home).
Install good outside lighting.
Get a trusted neighbour to keep an eye on your property.
Leave radios or lights in your house on a timer to make the property appear occupied.
Make sure the fences around your garden are in good condition.
Secure bikes at home by locking them to an immoveable object inside a locked shed or garage.
Keep ladders and tools stored away; don't leave them outside where they could be used to break into your home.
Ensure side gates are locked to prevent access to the rear of the property.
Ensure rear fencing is in good repair.
Improve natural surveillance at the front of your property i.e. trim high hedges.
