This elderly shopkeeper shows how she has survived without CCTV or metal shutters - using antique style wooden poles.

The grocery store in Nakhon Ratchasima, northeastern Thailand, has used the same security measure to lock up every night since they opened in 1958.

The woman, named Kunpa Dang, lifts the large teak wooden poles into grooves on the floor. A wooden 'lock' is then pushed into slots in the roof to hold the beams in place - forming an unbreakable prison-like set of wooden bars.

Kunpa, who took over the shop from her parents, said: ''This is very secure. I have never has anybody try to get inside. I would not change this for the modern security. People can still abuse that. But they will never get into my shop.''

The traditional style wooden security system was filmed while being studied by history lectures from a university in a neighbouring province.

They joked: ''This is Thai wisdom from more than half a century ago. This was the old way to stop thieves.''
