Lens mounting
The camera accepts CS-mount lenses. C-mount lenses can be
mounted using a lens adapter ring. DC-iris lenses are
recommended for the best picture performance. The camera
automatically detects the type of lens used and optimizes
performance accordingly. A spare male lens connector is
provided.
Note
If a short circuit is detected on the lens connector, the on-
screen display (OSD) failure message LENS SHORT CIRCUIT is
shown. The lens circuit is automatically disabled to avoid
internal damage. Remove the lens connector and check the pin
connections.
CAUTION!
To avoid damaging the CCD sensor when using a C-mount lens,
make sure a lens adapter ring (not included) is mounted onto
the camera before mounting the lens.
Lenses weighing more than 0.5 kg (1.1lbs) must be separately
supported.
