A PILOT scheme to protect pensioners from bogus callers has been declared a success.

A group of elderly people in Hartlepool were chosen to take part in the scheme which tested crime-fighting equipment.

The residents had door announcers fitted inside their homes, to remind them to be careful when answering the door to strangers.

The electronic sensor uses a voice chip and infra red detector to issue a pre-recorded message, which is activated by a caller approaching.

The device reminds the occupant to perform security checks, including using the door chain and asking for identification.

Some Hartlepool residents have had the door announcers fitted for the last month, as part of a nationally-funded trial.

Sergeant Lynn Beeston, of Hartlepool police, said: "The feedback we have got back from the residents is very positive.

"The people who had the systems were very glad to get them."

Plans are being drawn up to move the boxes to other homes in the town.

Sgt Beeston said: "They were not meant to be a permanent fixture. The idea is to get people into the habit of making security checks.

"Many of those involved in the trial are now in the habit, and some have actually got annoyed by the system, so it is time to take it out and move it to new homes where it can be of benefit."

Sgt Beeston said that anyone who wanted to keep the system in their home would be allowed to do so.
