The V8415 MFM can be configured to provide a range of functions associated with CCTV systems control: - Text + simple graphics overlay 28 x 11 lines, multiple colour, 4 zoom ranges. Display routines available to filter displayed text out of incoming serial data stream -CVBS or Y/C Outputs available - SerialRS232 input/output for control and/or display purposes - 8 channel A/D for feedback functions including Pan/Tilt position -2 channel PWM out for 10 bit accuracy DC output -I2C master/slave allowing provision of time/date or non-volatile memory functions - Port available for 4 x 4 keypad or LCD display -8 bit uncommitted general purpose parallel port The flexibility of this module can be further expanded by attachment of a daughter board to the underside using the existing I/O connectors. Functions such as additional timers, power drivers for P&T motors, custom interfaces etc. may be fitted, resulting in a compact module of less than 95 cm3. A range of existing firmware routines in a mix of assembler and C are available.

The Video Overlay Unit enables data from equipment generating text data streams such as Traffic Monitoring Equipment, to be burnt in over a video picture obtained from traffic cameras located at the monitoring scene. Employing software configured for the type of equipment used to record traffic data, the incoming stream is stripped of data not required for display, and reformats the display order to suit the required on-screen presentation. It can be supplied in free-standing or rack-mounted format.

This DVD/HD recorder has been designed to overcome the limitations of VHS tape based recorders in the Video Survey market. This unit employs a small, low-power 1GHz PC platform, large hard drive and DVD writer combined with video overlay and Picture-in-Picture facilities. Using the included automation software, many days of video recording are possible, with storage onto HD or DVD depending upon selected duration. For unattended use, all configuration parameters such as the recorded site name, required duration, media to be used etc. can be preloaded onto the DVD disc, leaving the automation process to start and stop recordings at the required times, then copy the image files to the DVD if required. An optional GPS unit can be fitted to ensure precise timings for recording and video overlay functions. External serial data from vehicle speed measuring equipment (for instance) can also be imported and burnt into the image.

This is a mobile PC-based solution for recording camera images overlaid with Text data from Traffic Monitoring Equipment (ADR) while capturing log files and handling all interaction with the ADR automatically. Using MPEG encoding to hard drive or to DVD, it compresses the image as necessary to fit on a single disc depending upon the recording duration chosen. It is capable of starting and stopping recording at preset times, overlaying site data including its ID and GPS LAT/LON position, comparing the ADR timestamp with actual time, logging onto the ADR and requesting the traffic data stream. It stores the raw flow data and can burn the DVD at the end of recording from the hard drive copy. Precise Time references are obtained from an external GPS/MSF module (V8441). It is fitted with the V8421 Text Overlay Unit, which strips the incoming stream of data not required for display, and reformats the text order to suit the required on-screen presentation.

The V8448 Camera is a sensitive day/night camera which incorporates ring IR lighting for 24 hour observation of vehicle wheel axles from a near-kerb position. The rugged case has been designed to minimise interest from passers-by, with the aim of looking like an electrical junction box. In order to guarantee good illumination both nearby and at the limits of camera range, a 2nd IR light ring has been fitted above the camera. Specifications for both units are as below. The unit is fully sealed to IP57. The IR window plate is easily replaced in the event of damage.

One important characteristic of the camera is the 48 zone backlight compensation capability – this will help maintain good contrast on dark wheel axles while operating with a high-brightness sky background

Designed primarily for Traffic-Survey use, the V8459 camera provides relatively high resolution colour images from a small CMOS module located in 32mm dia pipe mounted vertically adjacent to a roadside located streetbox. One of the design aims was to make the unit both inconspicuous, vandal-resistant and waterproof.

While designed primarily for for Traffic-Survey enumerator use, this unit seeks to overcome the problems of controlling frame-by-frame DVD playback while at the same time using hand-held equipment such as a manual enumerator unit, as is often used for traffic flow counts. Typically, the time taken to move a hand from the manual counting mechanism to locate the remote control, then locate the correct button and depress it – can amount to several seconds, by which time the vehicle(s) under scrutiny may be out of the picture. This unit provides instant control without moving a hand from the unit Using a short range RF wireless link, it can be located under a desk or where convenient to suit the user.

This Camera forms part of the VES/XTVision range of body-worn cameras and associated video equipment for Professionals in the field of Search/Rescue and Extreme Sports activities. The high-resolution CCD, wide-angle lens and integral dual High-intensity LED lighting are installed in a custom sealed, low profile rugged two-part enclosure, It was designed primarily for video feedback of the scene for armed-response units in the UK police force. A separate dog-mounted backpack containes a battery pack and encrypted video transmitter. Video is transmitted back to the dog-handler who can then assess the level of armed-threat to the team from a vantage point close to the target.

GPS

The V8438 GPS OVERLAY UNIT is based on the Ves V8415 Multi-function Module which has been successfully used in a range of video display applications from traffic flow analysis displays to Control System Menu Display units for use in submarines. Version V8438-01 uses a Sirfstar 1 12 channel GPS module and an internal active antenna for the overlay of position, heading, speed, date and time onto the video signal before recording or transmission. V8438-02 is configured for smaller size and lower power consumption. For automatic map tracking V8439 daughter board can be attached to the underside using the existing I/O connectors. This takes the GPS data and generates teletext-like data on unused video lines, allowing our Video Modem V8443 to automatically extract the data as a serial signal at the receiver. The signal may be fed to any standard mapping software accepting NMEA position data.

The GPS Explorer kit provides a unique collection of modules which can be built up as needed to provide a whole host of applications ranging from: · GPS data logger - ( vehicle or person tracking) · Vehicle navigation in conjunction with any navigation software using NMEA input, including Autoroute and TomTom software running on your laptop or PDA · Remote control over the mobile or landline network · Vehicle tracking using GSM/GPRS with external GSM module.

Compact 12V, 12 channel car-mounted SirfStar GPS unit for connection to laptops or PDA's. Interfaces to all
standard map software with a NMEA input capability. Comes with additional cables that allow you to
send your position over mobile phones to another unit at your base station
when additional software has been installed.

Designed primarily for traffic survey use, this unit overcomes the practical limitations of mechanical clickers currently used by traffic flow enumerators. Today, revenue from privately-funded roads in the UK is a major business, dependant upon accurate records of vehicle flow and classes of vehicle using each road. This unit provides a means of logging up to 30 classes of vehicle for up to 3 directions of simultaneous traffic flow. Each log when complete, can be sent to a remote server for analysis by modem or direct serial link. This avoids the time-delays and potential errors introduced by conventional transcription to paper first. Bespoke software is included for processing the received files.
