Main Cabinet

Based on the real-time embedded operating system of Linux, the system is more reliable, handy, small in size, and adaptable all kinds of vessels. With a power of 20W without any ventilation fans, the Main Cabinet Unit body is designed to be closed, no dust to enter. 

Record the datas of recently 720 hours, 30days, and it containong VGA image in 4 lines, 61162 signals in 24lines. Voice from bridge in 6 lines, VHF audio in 2 lines.

All spare parts are independents developed and produced by Headway factory, sufficent to meet the need of customers, with an advantage of high quality at low price, complete sevice net all over the world.

Power module is Internally installed in main cabinet, applicalbe to 220V/110V 50Hz/60Hz and of marine electrical system, which can be access tomarine Emergency power directly. No need adjusts manually, switch to marine backup power of 24V to go on working when main power is off, automatically switch to internal installed battery for supplying power once marine emergency power is off.  Record voice data for 2 hours continously. Usage life of Maintenance-free battery is around 3 years.

Remote Acquisition Unit

As to the device without standard digital interface, the editable signal gathering module can be installed at the scene to obtain necessary digit and analog data.

Support 64 active or passive switching signals, 8 analogs (0~±10V) signals access.

Remote Alarm Unit

It conducts round-the-clock monitor of the VDR with acoustic and light alarm indications, the liquid display will enable you to more easily get rid of faults.

Microphone Unit

It has an embedded design, elegant outer appearance, easy to install with self-inspection function in order to avoid the failure of audio signals gathering due to the damage of microphone. Its in-built amplifying function enables the transmission of high-fidelity audio signal in a long distance.

Reliable Protective Data Capsule

Record vessels voyage data for 48 hours

The self-developed Protective Data Capsule is more inexpensive and competitive.

The Protective Data Capsule is a special one with high technology, which can be produced by only a few manufacturers in the world.

EC61996 specifies that the final recording medium for the VDR must be installed in the capsule in accordance with the following standards:

? Penetration: an object with a prick of 100mm diameter and a weight of 250kg falling from 3 meters’ above

? Impact: 50g semi-sine pulses for continuous 11ms.

? Fire-resistance: 260℃ low temperature for 10 hours, and 1100℃ high temperature for 1 hour

? Pressure in deep sea: 30 days at 60 Mpa (6,000 meters depth) under sea and 30days dipping.

Float-Free Protective Data Capsule

Record vessel voyage data for 48 hours

This multi-used float-free storage unit includes an S-DVR storage medium and a conventional GMDSS satellite position indicator beacon, also called EPIRB.

After the protective data capsule falls into water, it will keep the valid information of the S-VDR and automatically float on the water surface. There is no need to look for it under the water. It is more convenient to locate and salvage it through satellite.

? signal transmission by Ethernet

? Solid storage medium for 32GB

? 2 power input lines of 24V and 4 signal lines for easier floating and separation.

? Complete GPS land mark at 406Mhz and 121.5Mhz

? Battery life is at least 7 days

? Complete release gear for automatic pressure

? hook is easy for refloating.
