Twisted Pair – Video Transmission
Series 65
Description
The Ernitec Series 65 is a range of units capable of
transmitting colour and black and white video
signals on twisted pair cables up to a distance of
1000 m. The Series 65 consists of a range of a
transmitter and a receiver, as listed below. The
Type
BVT-65
BVR-65
Series 65 twisted pair transmission equipment can
be used in a variety of applications, such as
linking a camera to a matrix, transmitting video
from a remote matrix to a main matrix or from a
matrix to a remote monitor.
Description
Boxed video transmitter with built-in 115 or 230 VAC power supply
Boxed video receiver with built-in 115 or 230 VAC power supply
The transmitter unit has a galvanic separator
thereby eliminating hum problems.
The loss introduced by the cable length is
compensated on the receiver by means of five
potentiometers which must be adjusted at the
time of installation.
The Series 65 is fully compatible with other
Ernitec twisted pair video equipment. However
the specified technical data including transmission
distance assumes the use of Series 65 equipment
only.

MVT-610 Mini transmitter
The Ernitec MVT-610 miniature twisted pair
transmitter is designed for transmission of colour
and B/W composite video signals on cable lengths
of up to 1500 meters (1000 meters when used
with BVR-65). This is a compact video transmitter
and due to low power consumption can be
connected to a built-in BNC plug and powered by
a camera. The MVT-610 is fully compatible with
all other Ernitec twisted pair equipment.

CHM-PSTP/2
The Ernitec CHM-PSTP/2 is a small power supply
and twisted pair transmitter, designed for supply
of 12 VDC CCD cameras and fits into the Ernitec
CHM/N-housings. The built-in twisted pair video
transmitter with galvanic separation can be used
on cable distances up to 1500 meters for colour
signals and 2000 meters for B/W signals. The
CHM-PSTP/2 is fully compatible with all other
Ernitec twisted pair equipment.
