Companies across Aycliffe Business Park have been armed with 20 crime-busting radios.
The communication tool have been funded by Police and Crime Commissioner Joy Allen to help tackle crime and anti-social behaviour on the business park.
The County Durham and Darlington PCC provided a grant worth just over £9,000 for the devices, which will help tenants on Aycliffe Business Park communicate with each other to warn of suspicious activity.
Committed to supporting businesses and retailers against crime, the PCC has funded the resources as part of a wider plan to expand Business Watch schemes across County Durham.
