for mobile NVR, which is recommend. possible not to have branded expensive stuff

Look for vehicle CCTV surveillance systems that have CANbus and GPS interfaces. CANbus will allow you to use vehicle telemetry information as metadata for CCTV with GPS offering mapping, location & speed. If you have G-Force sensors this can also provide alarm activation for sudden braking or impacts. See something like http://www.vidiwave.co.uk/datasheets/bus_coach_pdf.pdf Ilkie i have found the local distributor. they did not bring in this product due to the price is at the high site. they recommend me other brand.

Geovision do have mobile DVR. what do you think on it performance?

for a public transportation purpose, of course there will be a camera and a mobile DVR/NVR install in the bus. here is my question 1. How to integrate the driving speed in the video recording? 2. Is it possible to auto transfer "today" record to server when the bus reach the bus terminal, let say the terminal with WIFI coverage? or any live transfer to server solution? 3. which brand/manufacturer has the complete solution? if require integrate, how to do it? 4. Any better recommendation to make the system better or any other feature can be include? thank you in advance for your sharing
