Identification; Product Description And Type Designation; Product Marking - Videotec NTC Manuel D'instructions

• This device was designed to be permanently
secured and connected on a building or on a
suitable structure. The device must be permanently
secured and connected before any operation.
• Comply with all the national standards during the
device installation.
• The device must be properly connected to the
earth circuit.
• Any device which could be installed inside the
product must comply with the current safety
standards.
• Before starting any operation, make sure the
power supply is disconnected.
• Installation category (also called Overvoltage
Category) specifies the level of mains voltage
surges that the equipment will be subjected to.
The category depends upon the location of the
equipment, and on any external surge protection
provided. Equipment in an industrial environment,
directly connected to major feeders/short branch
circuits, is subjected to Installation Category III. If
this is the case, a reduction to Installation Category
II is required. This can be achieved by use of an
insulating transformer with an earthed screen
between primary and secondary, or by fitting UL
listed Surge Protective Devices (SPDs) from live
to neutral and from neutral to earth. Listed SPDs
shall be designed for repeated limiting of transient
voltage surges, suitable rated for operating voltage
and designated as follows: Type 2 (Permanently
connected SPDs intended for installation on the
load side of the service equipment overcurrent
device); Nominal Discharge Current (In) 20kA min.
For example: FERRAZ SHAWMUT, STT2240SPG-
CN, STT2BL240SPG-CN rated 120Vac/240Vac,
(In=20kA). Maximum distance between installation
and reduction is 5m.

4.1 Product description and type
designation
The thermal camera provides vision in fog, rain,
smoke, across long-range distances or even in
complete darkness.
It is possible to use this housing for a wide range of
high-security day/night surveillance requirements,
such as: monitoring and rescue in the event of
a fire, public safetyand airport, industrial and
environmental surveillance.
The thermal video camera is a non-cooling vanadium
dioxide (VOx) microbolometer with a spectral range
from 7.5μm to 13.5µm. It delivers a thermal video of
320x256 (PAL) and 320x240 (NTSC), with an image
frequency of 8.3fps or 25 fps (PAL) and 7.5fps or
30fps (NTSC). The high sensitivity NEdT 50mK at f/1.0
ensures an optimal thermal imaging. It supports 2x
or 4x digital zoom. A choice of lens sizes is offered
depending on the detection distance required.
The stainless steel housing allows it to be installed in
environments with highly corrosive external agents,
such as marine, industrial or chemical environments.
The NTC housing can be installed on NXPTH Pan & Tilt
head, to obtain a complete positioning system.
