An access control portal 20 comprising a barrier movable between positions in which it blocks and allows access, and at least one time of flight camera 24, 25 arranged to monitor persons entering or exiting the portal. The portal may comprise a barrier 22 pivotally mounted to a body 21, wherein the barrier sweeps through a zone 23 that extends beyond the body. The camera may monitor a zone swept by the barrier, or a zone 27 beyond the reach of the barrier, in order to ensure that the barrier opens safely. Upon detection of a person approaching, the barrier may be opened to allow free passage. There may be at least two time-of-flight cameras arranged to monitor opposing directions. The camera(s) may be used to sense the direction and/or number of people. The portal may comprise two housings facing one another to define a passage, each comprising a movable barrier and at least one TOF camera. The portal may be a passgate, which is a turnstile having thin supports such that the opened barrier extends 23a, 23b beyond the supports in the passage direction.
