Survtech,
Thank you for that, I can understand casinos keeping their CCTV system info closely guarded.
From speaking with the potential installers, some are still advising to go with an analogue system with 1200tvl cameras. I am not convinced by this and have kept up my research with systems and what is needed to set them up.
As far as cameras go, I think 720p IP should be sufficient, though will have to test makes and models to check card visibility at distance camera would potentially be from table.
We have worked out that we would need around 60 cameras to cover the whole gaming floor and then just room overview cameras in other areas (restaurant, bar, kitchens, stock rooms, staff rooms, offices)
I have found this link and from what I can see, as long as all the different parts of the system can be bought and are compatible, then a technician should be able to set up a similar system. http://support.unisight.net:2700/64ch%20720p%20Solution.pdf
