TransVu

Introduction

TransVu is a Digital Video Recorder specically designed for transport applications. With a ruggedised

design to withstand the often heavy vibrations generated by vehicles, TransVu is ideal for mobile

surveillance in all types of vehicle – such as taxis, vans, buses, trains and heavy goods vehicles.

Part of the NetVu Connected product range the TransVu is fully network capable and supports the Internet

standard TCP/IP protocol. As the TransVu is a mobile product the unit can be accessed via wireless LAN

or GSM / GPRS / CDPD. Supporting upto eight video inputs, two audio channels, panic alarm handling and

intelligent power handling the TransVu is a powerful transit recorder.

System Documentation

The Installation and Operation of the TransVu are detailed in the manual suite which consists of:

• Quick Start Guide - Initial steps to get the TransVu up an running to basic operation.

• Installation Guide - Full instructions to install the TransVu unit.

• Conguration and Operation Guide - Full conguration documentation for the TransVu.

TransVu

Installation

This section is seperated into Physical Installation (tting the baseplate, shock absorbers etc.) and System

Installation (cable connections, etc.)

Physical Installation

Product Orientation

Although the TransVu can be mounted horizontally or vertically, it is recommended that it should be

mounted horizontally using the supplied mounting kit, with the multipole plug facing the rear of the vehicle.

This ensures the accelerometer gives the correct reading.

It is important that sufcient space be provided for the unit and cable connector.

Installation space required for the TransVu

The TransVu is xed to the vehicle via a mounting plate.

It should be mounted as low as possible within the vehicle, on a secure base free from resonance and

secondary vibrations.

The TransVu is xed to the mounting plate via four shock absorbing xings. This dramatically reduces the

vehicle vibrations and enables the TransVu to operate in harsh shock environments.

Vibration will cause the TransVu to move on the shock mounts. Therefore a reasonable clearance must be

allowed around the unit.

A suggested tment area of 350mm (13ﬂ”) x 380mm (15”) x 140mm (5” ) is recommended.

Care in feeding cables

Ensure the cables feeding the multipole plug are clamped to avoid any vibration being transmitted along

them to the unit. Cable clamp posts are provided on the baseplate. The two clamps (highlighted) must be

used to prevent the cable vibrating loose.

Notes on installation space

Additional space is required around the plug to accomodate the disconnection of the cable from the unit.

TransVu

Mounting the Baseplate

The TransVu baseplate should be secured to the vehicle using appropriate nuts, bolts and shakeproof

washers. The baseplate should be mounted horizontally. Ensure the correct orientation of the TransVu once

it is mounted on the baseplate. The Transvu multipole socket should face the rear of the vehicle, at the top

of the base plate, and the cable clamp should be on the right hand side.

These details cover installation using the Rev B metalwork.

Mounting restriction for correct G-force implementation

If the G force detectors are tted in the TransVu, the baseplate must be correctly orientated within the

vehicle.

Fitting shock absorbers to the unit.

This procedure to mount the shock absorbers to the TransVu must be adhered to, this will ensure minimum

movement due to vibration:

Fitting the TransVu to the baseplate

The Transvu multipole socket should face the rear of the vehicle, at the top of the base plate, with the cable

clamp on the right hand side.

Note: The cable clamp is provided to reduce vehicle vibration being transmitted from the cable loom

through to the TransVu. Ensure that the cable loom between the clamp and the multipole socket

does not touch any part of the vehicle.

Cable Connections

Multipole Connector

All connections to the Transvu unit are made via a 55 way female multipole connector.

The connector is mated to the TransVu as follows:

Connecting vehicle power

TransVu is designed to run on vehicles with a negative earth or negative ground system.

When the unit is running the power input is reﬂected on the power output pin, being relay contacts switched

under software control.

This allows ancillary equipment such as cameras etc. to be powered down automatically preventing

unnecessary drain on the vehicle battery.

Vehicle Data Logging

Example wiring - Taxi

This is a simple implementation using two cameras.

Two alarm inputs are wired up, one indicates that the electronic door safety locking is operational and the

other provides a panic button for the driver.

The vehicle ignition sensor will automatically power down the unit shortly after the ignition is switched off.

It also cuts power to the cameras to ensure the vehicle battery is not attened. Recorded images can be

viewed on the TransVu playback station.

Example wiring - American Schoolbus

This is a typical schoolbus implementation using four cameras and two microphones. Three cameras and

one microphone are housed in a single dome. The driver camera is in an individual housing. The second

microphone is shown as a single cable type. If the microphone has a powered line amplier, power must be

sourced from the switched power from the Transvu.

Two alarm inputs are wired up, one to give indication that the stop arm is operational and the other to

provide a panic button for the driver.

Vehicle ignition is sensed so the unit will power down shortly after the ignition is switched off.

This will also cut power to the cameras and ancilliary equipment, ensuring the vehicle battery is not

attened.

Speed recognition is via a powered sensor. Recorded images can be viewed on the TransVu playback

station.
