■ Download Software
Specified period of historical data can be downloaded from any store medium like VDR, Reliable Protective Data Capsule, Float-Free Protective Data Capsule for checking. Download speed is fast,neat,easy for accident investigation.
■ 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.
