Provided Accessories
Features
Ⅵ DSP with a wide dynamic range
Even objects that have a large difference in brightness can be monitored clearly.
Ⅵ Day/night surveillance
When the light is low, the camera pictures can be switched automatically to black and white pictures.
The camera is also compatible with IR illumination (wavelength 850 nm to 880 nm).
Ⅵ Private masking facility
When the camera target area contains an area that is required to be hidden the camera can be set accordingly in order to mask it.
Ⅵ Simplified waterproof design
The simplified waterproof design (IEC529) of the camera allows it to be installed in many locations, including under eaves,
provided that it is not subjected to direct water splash. (However, note that the camera cannot be used outdoors.)
Ⅵ Optical + electronic zooming
The 27X optical zoom lens and 10X electronic zoom circuitry allows the camera to be used even in surveillance situations in
which the object is very small.
Ⅵ High-sensitivity CCD and bright zoom lens
The CCD features an improved sensitivity of nearly 70% over the previous model and the zoom lens has a large aperture ratio of
f1.4 (at WIDE end). These features provide the camera with a high sensitivity of 0.5 lx in the color mode (25% output, AGC 20 dB,
WIDE end, electronic sense up x2).
Ⅵ High-speed pan/tilt table
The high-speed rotating table with a horizontal panning speed of 300°/sec. and a vertical tilting speed of 180°/sec. makes it
possible to recall a preset position quickly.
Introduction
WARNING
• Install the unit on a strong and stable surface.
This unit has been designed to revolve at high speed. Due to its weight (about 2.4 kg) and the vibrations it may be subjected to, the
camera must be mounted to a sturdy and stable material. If the ceiling material lacks strength, for example it is made of a decorative
laminated material or plasterboard, then the mount should be reinforced using materials such as veneered plywood. If such reinforce-
ment is inadequate images may fluctuate due to vibration or, in the worst case, the camera may fall and cause a serious accident
should there be anyone below it.
• For installation, use the provided ceiling mount and the optional flush mounted ceiling bracket, which is sold separately.
When installing this device the provided ceiling mount and the optional flush mounted ceiling bracket, which is sold separately
should be used. Also be sure to connect the drop prevention wire and tighten all screws and nuts firmly.
• Power the unit with the rated power voltage.
The power rating for this unit is 24 V AC, 50 Hz/60 Hz. If a power above this rating is supplied, a malfunction will occur or, in the
worst case, smoke or fire may be produced.
• This unit offers a certain degree of protection against any damage either to itself or to its connection cable that might result from
indirect lightning strikes, but it is not capable of preventing all damage by lightning strikes. For example it is not protected against
a direct lightning strike. If lightning damage can be expected in the place where the unit is installed, be sure to take countermeas-
ures by adding an arrester to the connection cable, etc.
CAUTION
• Installation of this unit requires special skills. Please be sure to consult your dealer about installation procedures.
If the mounting screws or nuts are not tightened sufficiently, the camera may fall from its installation location. Be sure to tighten the
mounting nuts firmly to prevent this happening.
• Inspect the unit periodically.
Check periodically for any deterioration of the mount sections or loosening of screws due to vibration and ensure that there is no
likelihood of the unit dropping.
