EC135 T2 helicopter
They operate an EC135 T2 helicopter. It has two Turbomeca Arrius engines and cruises at 120 kts. It was purchased new for £3.4m in April 2004 to replace the AS355 twin squirrel helicopter, which had been operated since the unit commenced operations in April 1998.
The helicopter has a pilot and two police air observers. One observer operates the camera systems and the other is the tactical commander, responsible for navigation, radio communications and tactics.
Ultraforce 2 plus TV Camera Thermal Imager
A 54 x-magnification colour TV camera and thermal image (Thermal image camera) camera coupled to a digital video recorder. The Thermal image camera camera distinguishes a scene based on different heat signatures. In general, living creatures (including people) are warmer than their surroundings and so are identifiable to the Thermal image camera. The Thermal Image Camera normally now can differentiate between police officers wearing uniform and members of the public/offenders, but sometimes is 'fooled' by other heat sources, most notably water or compost heaps.
Spectrolab Nightsun II
A 3D-million candle power searchlight with variable beam. Used as a search tool in conjunction with the thermal imager. When conducting a search like this the searchlight is often used in a diversionary role lighting the area not covered by the thermal imager. This can also be ``slaved`` to the TV/TI camera.
A 700 watt public address system incorporating a siren
A microwave downlink enabling TV pictures to be transmitted to both Nottinghamshire and Derbyshire force operations room and to a number of briefcase receivers these can be fitted into police vehicles as well'. This can be especially useful in pre planned operations allowing scene commanders to see what is actually happening.
