Abstract
There is described a multi-headed camera comprising a camera base, multiple camera heads coupled to the camera base, each camera head comprising a camera lens defining an observation angle, each camera head being configured to pivot such that the observation angle may vary between a minimum observation angle and a maximum observation angle, and a protective shield attached to the camera base, extending over the camera heads and shaped such that for each camera head a distance between the shield and the camera head varies as a function of the observation angle. Attached to each camera head is a resiliently deformable and flared gasket positioned around the camera lens and extending toward the shield. The gasket is configured such that, for any observation angle between the minimum and maximum observation angles, the gasket contacts the shield about a closed light seal path for preventing light from passing between the shield and the gasket, and reaching the camera lens.
