designation
The EC-940-PTZ-A, EC-940-DUA series explosion-
proof pan-tilt-zoom (PTZ) camera positioning devices
have been designed to allow movement, on both a
horizontal and a vertical plane of a in-built camera
and to operate in industrial environments in which
there may be an explosive atmosphere due to gas,
vapours, mists, or air or powder mixtures.
EC-940-PTZ-A, EC-940-DUA PTZ devices, supplied
complete with an in built camera, are made of AISI
316L electropolished stainless steel.
This unit basically consists of a base, a main body and
a housing for the camera.
Versions with a second housing for thermal cameras
are available.
On the base there is a connection compartment
that allows very easy cabling of the system, and it
comprises the power supply electronics. There is a
hole 3/4” NPT on the base and the connection must
to be done in conformity with IEC/EN60079-14.
The main body contains the motors for horizontal
and vertical movements and the CPU and video
boards.
The camera housing contains a day/night module
with its electronics, an heater (Ton 15°C, Toff 23°C)
and a built-in wiper.
The PTZ device has an IP66 protection degree and
its operating temperature is - 40°C to 60°C (-40°F /
140°F).
EC-940-PTZ-A, EC-940-DUA PTZ includes integrated
high-performance pan-and-tilt telemetry.
EC-940-PTZ-A, EC-940-DUA PTZ offers continuous,
high speed rotation, positioning precision and
superior image quality, utmost sturdiness and
simplified system configuration.
Speed and precision are the predominant pan-and-
tilt characteristics, reaching 100°/s in continuous
horizontal rotation, with vertical range between -90°
to +90°.
EC-940-PTZ-A, EC-940-DUA PTZ manages the preset,
auto-pan and patrol functions with an accuracy 0.02°.
The unit performs a continuous control of its position
to verify the correct positioning of the camera at any
time. This is a very useful function in case of severe
environmental conditions, such as strong wind and
heavy vibrations.
The choice of integrated SONY cameras offer 36x
and 28x zoom lenses, which allow the recording with
exceptional precision of both close-by and far away
objects, as well dynamic privacy zone masking.
Besides the OSD (On Screen Display) configuration,
the system is equipped with an RS485 interface for
complete system control and for the updating in
remote mode of the latest firmware version.
The simplified set-up software interface offers typical
preset configurations or the possibility to customize
the complete system.
