Looking for low cost solution for a customer to get register data overlayed on video. He really wants an IP system but doesn't want/need the high end data analytics, just the information stamped on the video. Only two registers.
Would it work to use two analog cams (one for each register) with VSI-Pro overlay device connected to an encoder? And thus sending the video with POS overlay to the Hikvision NVR.
"Would it work to use two analog cams (one for each register) with VSI-Pro overlay device connected to an encoder?"
I think so. Those VSI-Pros only work with SD analog video, you input the raw video and the PoS data, it 'prints' the PoS data on top of the video stream and outputs the combined version.
If it's low cost that you want, why not go for a Hikvision tribrid recorder that supports TVI, SD analog and IP? This way you do not need an encoder and can connect those feeds directly into the recorder plus you can add in other low cost HD-TVI cameras or some IP.
Jason, as far as I can tell, many Hikvision NVR's and DVR's support the recording of POS overlays direct from the register via serial port. Of course in your case since you have two feeds, you need to get a serial IO box that converts them both to TCP/IP, (unless you purchased two small NVR's).
Hikvision has a four channel serial IO converter model. Hopefully the cost would be offset be not needing the two VSI-PRO's and encoder/DVR.
I am from Hikvision. That serial IO box is not a Hikvision product. It looks like the local office who made that PPT sourced and sold it on their own. The POS integration is purely thru the DVR/NVR, no special cameras are required.
Regarding conflicting information, I would recommend that people work with their local Hikvision representative.
In addition, I would recommend that Hikvision reign-in any rogue branches who are publishing under the Hikvision imprint, as in today's age of 'Google', it is naive to expect people will not be confused by such materials like the one above.
