RADIATION-TOLERANT CAMERA

R981 COMPACTTM
System Camera

The R981 CompactTM camera range builds on
the success of the standard R981TM but offers afull radiation tolerant pan, tilt and zoom camera
with a smaller sized envelope. Ideal for locatingin areas where space is at a premium, we havecombined the camera and pan and tilt into an
integral unit and provided three positions for
additional lights and microphone. The R981
CompactTM can be configured into multi camera
configurations, or a single camera system canbe supplied.
