Historically, each of the Met's Borough Operational Command Units (BOCUs) had its own control room, known internally as the 'CAD Room' (for Computer Aided Despatch) which dealt with incoming non-emergency calls and with despatching police to all calls in that area.
[1] Following completion of the C3i programme in late 2007, all Met communications are dealt with at three dedicated centres at Hendon, Bow and Lambeth, covering west; north and east; and south London respectively.
Patrol officers are dispatched through the Airwave radios and by sending information direct to the MDT terminal in every police vehicle.
All calls are given one of four grades:[4] Once the CAD report has been created, it is passed to the relevant Dispatch for the borough in question to decide what officers to deploy to it.
The Duty Officers are responsible for decisions made within the centre and are also entrusted with ensuring the well-being of the staff under their care.
Their responsibilities include overseeing Operators, taking charge of challenging situations, and making final decisions on incident closure.
Additionally, a subset of Supervisors manages the First Contact process, ensuring accurate call handling.
