ak357 0 Posted November 1, 2011 Would you make the casino switch back to analog when you get the job? Woow great ? watch for b/w mini bullets and Dahua DVR it's just my opinion Xellbuy u are my Hero today ! Share this post Link to post Share on other sites
nDAlk90 0 Posted November 1, 2011 It was joke. We know analog sometimes is better in low light as rory emphasize. This is why rory always emphasize price does not mean better performance. Xellbuy u are my Hero today ! Share this post Link to post Share on other sites

survtech 0 Posted November 1, 2011 i think his casino uses analog now " title="Applause" /> Correctamundo! No IP infrastructure, no budget (would cost millions) and nowhere to put the necessary switching equipment. Wouldn't go full IP at this point anyway - PTZ latency is a deal killer, for one; unproven long-term reliability, for two; consistent 30fps frame rate, for three and low light performance for four.

survtech 0 Posted November 1, 2011 Actually, you would be hard-pressed to find any casino willing to release even still shots; never mind video. I wasn't kidding when I said it's a fire-able offense. And it's not small - 2000 slots and 70 table games. More than 1000 cameras. That's how you can get IDs with analog. Cover every square inch with suitable cameras.

dustmop 0 Posted November 1, 2011 By the way, the trick won't work with every camera. The chosen cameras have to be able to aim nearly fully horizontal. That's something many domes can't do and even fixed domes in back boxes can have issues because the dome itself is either too small in diameter to be able to fit a camera and a 5-50mm lens down inside the bubble or the bubbles get optically distorted near the edge. No kidding! Making Pelco cameras fit in a DF5 housing while looking down a long hallway is a royal pain the butt. Requires a right-angle BNC, and LOTS of patience and practice. In some of the hallways, I have taken to mounting the cameras in the wall instead of the ceiling. Sure, it's a dome in/on a wall and seems odd, but if it lets me see what I need to see, then so be it! On the gaming floor, when I need a fixed, long, almost-level shot, I just use the HUGE DF9 housings. Monstrous things. If I could get some example shots out, I would, but I'm in the same boat as survtech here; my ass would be FIRED. Casinos generally don't mess around when it comes to their coverage. Now the prosecutor's office... those guys LOVE leaking the footage they subpoenaed to the media any chance they get. Share this post Link to post Share on other sites

By "fully horizontal" do you mean looking straight out the top of the dome or 90° out the side? Share this post Link to post Share on other sites
survtech 0 Posted November 1, 2011 No dome has a problem looking vertical (straight down when mounted on a ceiling). Many can only tilt up 75 or 80 degrees from straight down. Not a problem for many shots but long corridors typically don't have the height. The camera has to be far enough into the bubble so that the lens can see through it, rather than getting blocked by the opaque part of the dome. When the camera is mounted on the ceiling it has to basically be able to see the ceiling; hence horizontal. There's a little leeway there but you definitely need at least 85 degrees. Also, the edges of many bubbles tend to act as part of the lens when zoomed way in. That makes focusing near impossible. Share this post Link to post Share on other sites
