<p>Improvements in or Relating to Surveillance Equipment An attachment to provide a standard single lens camera with the capability to see in more than one direction and outside the ordinary field of view of the lens. The attachment utilises mirrors either fixed or motorised in front of the lens. Consequently less cameras may be required to provide the same coverage when compared to prior art cameras. This has the advantage of reduced the cost of providing adequate security coverage. The attachment can be retrofitted to an existing camera which improves the functionality of the camera.</p> |
