I work with underwater robots(ROV's) and I'm looking for a way to log latitude and longitude of the vehicle with the video as it's being recorded. I can send the text to a tcp or udp port and was wondering if there's a way to do this using the POS feature on the DVR?

The DVR's I use have serial (rs485 or RS232) POS inputs as well as a setting to send the data to a TCP port over ethernet. I could get some software to take the ethernet POS data from the GPS and parse it to a serial port, but it would be a bit clunky.

A camera with GPS is an interesting idea except the GPS data is coming from a transmitter on the underwater robot, not an actual GPS. There is a GPS compass mounted to a pole on the side of the boat and on the bottom of the pole is an acoustic transceiver that transmits a ping to a responder mounted to the underwater robot. The offsets between the transceiver and the responder are calculated in relation to the GPS compass and the result is depth, latitude and longitude of the robot, which is what I need to record. Also, it would be preferable to log the position as a text file with the video rather than have it as just an OSD.

It's a pretty sophisticated GPS that lets you create data streams. You can select the IP address and port no that the data string is exported to. I don't know much about networking but I experimented with a couple of DVR's by setting the GPS data stream to the DVR's IP address and POS port but no data came through. I think there are various POS protocols that the DVR is looking for with rules for carriage returns etc. Maybe I need to get some code written that converts the GPS ASCII string to the protocol that the DVR will accept? The alternative is a DVR that the underwater robotics industry uses like VisualDVR which is a 4U rack mount PC that costs about $12,000 + yearly license fees which is overkill for my purpose.

That video was recorded on a $20,000 PC based DVR that has a lot of bells and whistles I don't really need. thanks for PMing me link to the Innova product.

I work with underwater robotics, and as I'm usually recording a few channels of video I've been using CCTV DVR's in various forms over the years. Inserting live text (date, time, location, instrument data etc) wasn't difficult with analog video, but now I'm building a tool that requires 8 channels of HD-SDI video with OSD. Does anyone know of a reasonably priced SDI text inserter? Alternatively, there may be a PC based DVR solution. The cameras will be recorded at 1080p, 30 fps. Any advice would be appreciated.

The feeds are recorded to the DVR. I thought I'd be able to use POS input but the DVR's just seem to log the data. The main problem is I need to export the video, either in a viewer, or in .avi format with the overlay embedded onto the image. Here is a link to a sample of the video with the overlay I'd like to display https://drive.google.com/file/d/0B43HGl1IXasRZzJ3RTByNXA5V28/view?usp=sharing
