  1. I'm interested in outdoor installations over large distances -- along city streets and along highways -- with large numbers of cameras. I'm especially interested in the communications and network aspects. What can people tell me about the equipment and networks they used, their experience with them, and any installation suggestions ? How was the equipment powered ? How much do such long-distance installations usually cost ? Thank you. -- Steve
  2. How many cameras will there be at each site? What kind of cameras? How, exactly, do you foresee the use of wireless? What wireless and fiber bandwidths do you have? Do you need to record, monitor, or both? Is this a critical installation where high reliability is important?
  3. I'm looking for inexpensive CCTV cameras with progressive scan but normal interlaced output. Several vendors announced such cameras in Spring 2003, but I have not seen any of them on the market. I'm looking for high resolution color cameras, as well as high resolution B&W cameras. To clarify what I'm looking for, I want a camera that, for NTSC, produces 30 frames per second where the two fields for a given frame come from a single, progressive scan of the image sensor, not two interdigitated scans. I need this to improve the capture of the images of moving subjects and objects. This is important to me because we make a new digital video security system that produces multiple, IP-based, digital video streams simultaneously and continuously per camera. The "forensics" stream captures at full (4CIF) camera resolution, minimal quantization and medium frame rate/camera. The "video matrix switch replacement stream" captures at 1CIF resolution, medium quantization and 30 frames/second/camera. The use of progressive scan is particularly important since we're capturing at full camera resolution (4CIF) instead of the more-common, 1CIF resolution, which discards every other field and would not benefit from progressive scan.
