Brentwood’s site survey revealed that to achieve perfect coverage across the large town they would need to install digital radios, plus booster equipment.
Brentwood recommended Motorola digital two way handheld radios DP3400 (without display), and DP3600 (with display) and the Motorola DR3000 repeater and antenna. They also recommended the Motorola desktop radio DM3600 (with display) for each CCTV room. The DP3400s were ideal for business use, whereas the sophisticated DP3600s were more suited to the police and other members.
Now shopkeepers can use their radios to call for help at the touch of a button. The CCTV controllers have the ability to monitor all calls, and supply critical data to the police using their strategically placed cameras.
Using their display radios, the police and controllers can see who is calling, and make private calls to individuals as well as groups. All radio transmissions are encrypted, which means no eavesdropping can occur in Harlow’s built-up area.
