(c)connected by secure data links to a recording system, and
(d)capable of producing, in one or more pictures, an image or images of the vehicle in relation to which the low emission zone contravention was committed of sufficient detail to show the vehicle’s—

(ii)enough of its location to show the circumstances of the contravention,
at the time of the contravention.
2. The device must include a recording system in which—
