For us, it would depend on the weight of the camera. We use quite a few Ganz ZC-D series domes. Their weight is right around 1 pound +/-. At that weight, fender washers and #8 x 1-1/2" to 2" machine screws are plenty sufficient, as long as the tiles and grid are in good condition. I would hesitate to even attempt to surface-mount a Panasonic WV-CW504s, which weighs 3.74 pounds or a Pelco SD423SMB0 PTZ, which weighs around 4.5 pounds, on a ceiling tile. If I did, I would definitely use some type of additional support.

Two words: Fender Washers.

That camera probably cost over $1,000 new.

By the way, most of the comments regarding the forgiving nature of PTZ control signal transport refer to RS422/485 signals. If the PTZ uses RS232, all bets are off!

#5 or #6 Welding Glass. Available at most welding supply stores. In bright daylight or brightly lit area, place welding glass against lens so that all light goes through glass and look at picture. Remove and replace welding glass and double check that image remains good. With glass in place, iris should open and when glass is removed, iris should close. If not, iris cable is not connected correctly or is working improperly. Adjust focus with glass in place. Remove glass, adjust lens iris controls for best picture in brightly lit scene. Go back and forth a few times to check proper operation of iris.

Just because they're a Korean company, doesn't mean they make their all of their products in Korea; likely due to labor costs.

With world best class technology and global manufacturing facilities in Korea and China, we are experiencing an average growth rate of 40% annually. In addition, we have achieved solid financial stability and acquired an A++ credibility rating with D&B Korea."

Yes, most CCTV cameras built in the 60's through the 80's used tube sensors. Mostly Vidicon our so-called Newvicon tubes. As did early TV cameras; including home video cameras. They were notorious for burning out if aimed at the sun; or even bright lights. When I first started in this field, one of the continuing maintenance items associated with CCTV systems was replacing the pickup tubes in the cameras. They would get weak and the video would get all washed out or go totally black. Also, they tended to get heavy burn-in.

Yes, but the PL-259 connector pretty much disappeared from CCTV cameras before the advent of solid state imagers. Also, look at the two holes on the top rear of the camera. I believe they say "focus" and "beam". Those are adjustments only found on tube-type cctv cameras.

It's also known as a PL-259 connector. In all likelihood, considering the size of the camera, the connector and its 110VAC power, the sensor is a Vidicon tube versus modern CCD and CMOS solid-state sensors. Vidicons were notorious for having longevity and image burn-in issues.

We are???

That would be a video auto-iris lens. Although video auto-iris lenses are still made and sold, DC auto-iris lenses are much more common today. A video auto-iris lens uses unfiltered baseband video from the camera to adjust the the lens' iris via active circuitry in the lens itself. It must be attached to a camera that has a suitable output connector. The more common DC auto-iris lenses have no active circuitry in the lens; the camera would contain that circuitry. The ALC adjustment would control iris compensation for bright spots within the field of view either by exposing for them in particular (peak) or by taking an average across the entire scene. The Level adjustment would adjust how much the iris closes under bright lighting.

Or add IR outside.

HDMI signals won't travel very far - maybe 45-50 feet @1080p without repeaters. Not very practical.

So much for the much-ballyhooed claims of the benefits of "uncompressed video". "Visually lossless" is all fine and dandy, but one of the main selling points the Alliance has been pushing was how much better "uncompressed" video is for live monitoring, and how NOT encoding on the camera allows better real-time viewing with no lag time. I guess they're finding that it's not as simple as all that... John, I agree with Soundy. With the advent of any form of compression, lossy or lossless, comes latency. There's no way around it! Another point, one of the claims of the Alliance is that all versions of their systems will be both backward and forward compatible. I don't see how they can maintain that compatibility while deploying/not deploying compression. Are some cameras going to deploy compression while others won't, depending on the resolution and distance requirements they have to meet or will all HDcctv cameras deploy compression or will it be switchable? How will legacy (v1.0-compatible) HDcctv systems handle v2.0 cameras?

I would call it persistent!

I'm far from trying to sell it. In fact, some members of the HDcctv Alliance might refer to me as a nuisance.

I agree with that. The cards are available, but I'm not so certain about the software.

SG Digital's HD offerings include PC-based Hybrids with 1, 2, 4 or 8 720p HD inputs with or without 16 analog inputs.

On the brighter side, there are those 1-8 HD cameras at 30fps each (15fps each for the 8-HD camera model). Supposedly, a standalone 4-channel HD DVR is coming out this fall, but I don't have details.

Welcome. Remember, that is pronounced Lon-gisland.

And table games are not noted for having the best lighting in many casinos. Even in ours, we are lucky if we get 80-100 lux at the surface and 10 lux reflected at 1-2 feet above, which usually translates to less than 1 lux at the camera.

Scott who? Don't you mean Craig Scott, about whom I referred.

Perhaps the HDcctv Alliance could straighten out the mess they've created out, then. Cable requirements being among the prime misstatements. Here are direct quotes from their website: http://www.highdefcctv.org/ No mention of RG6 there! Not counting having to rewire the site with RG6 Todd Rockoff, Chairman and Executive Director of the HDcctv Alliance and Craig Scott, CEO at OVii and a highly vocal supporter of HDcctv have posted numerous and often unwelcome statements just about everywhere touting the supposed benefits of HDcctv while conveniently ignoring pointed questions and criticisms of the technology. The Alliance's marketing blitz has continued unabated in many security publications, forums and other venues for at least a year without any product available to sell. Even as they post so-called "success stories" about a handfull of HDcctv installations, it appears that the equipment used in most, if not all, of these doesn't even meet the HDcctv Alliance's v1.0 specification. Then they ignore legitimate questions about the equipment used or some of the outrageous claims being made. In an article published in Security Director News Casino 'all over' HDCCTV installation Approval of technology means casinos 'know nothing will get by them' By L. Samuel Pfeifle - 07.13.2010), the integrator claims "Now, four cameras with 1280 x 720 resolution, and one 2-terabyte DVR can cover an entire gaming pit, he said, which used to require as many as 24 analog cameras". The claim is obviously exaggerated, since one 720p camera couldn't possibly have sufficient pixels to replace six analog cameras; especially in a gaming environment. One for two? Maybe. One should be highly wary of any new, so-called "disruptive" technology (their description) that starts off by plastering marketing hype all over the place, including in discussions that have nothing to do with their technology, and whose biggest promoters refuse to answer questions whose answers might reveal that the Emperor Has No Clothes.
