Hi all I am looking at getting a RS485 scanner and controller for a Raytheon Thermal TSC security camera I have. The Camera is mounted in a Pelco 3515-2 enclosure. What I would like is a controller that can be put into a auto mode scanning sometimes a small area and sometimes a larger area. Is it posible to get a controller I can program to scan like that? With different presets that I set up the scan speed and area. I have looked at several scanner controllers but none have in the description if this is possible. I would appreciate any leads on a controller. I really don't know what they are capable of doing in auto mode.

Hi I just bought a Ganz DR8N DVR. I bought this DVR because it was capable of recording at 704X480 resolution thinking this would get me better recorded video...this is a higher resolution than the Hi-Sharp DVR I am replacing. The problem I have is the video does not look as good as the Hi-sharp when set to the Maximum resolution and quality. The Ganz looks more blocky. Both have Mpeg 4 compression. The KB per frame at the best settings are 19-45 with an average of 32 for the Hi-Sharp and 6-16 KB for the Ganz. I would like to find a 8 channel triplex DVR with the best possible recorded video for under $1000. It should be capable of 7-15 FPS at 704X480 resolution on at least 4 channels at a time. It is for my residence I would like at least 2 weeks worth of storage, I have (2) 500 gig hard drives for the DVR. At the present time I have 4 KT&C .0003 Lux Bullet Camera's with 600 lines resolution and some I.R. Illuminators. I do continuous recording, but timer recording would be a good thing to have also. I don't use it for remote viewing over the internet, but most DVR's I have looked at in that price range have remote viewing. A CD burner is not absolutly needed as long as it has usb backup. The Live video is much better on the Ganz, but I really need a DVR that records the same quality as live view if that is possible? Can anyone recomend a DVR That would work for me? I am using RCA to BNC adapters for my video connections to the DVR, One other thing I noticed was if I have just the center part of the RCA cable in the Blockyness smoothes out, but I get some horizontal lines. This is true for the Hi-Sharp and the Ganz DVR. Why does the Video get less blocky? Any help with these problems would be much appreciated, I Plan on returning the Ganz if they will let me or exchange it for somthing with a better recorded video. -Rod-

3.6mm lens are designed for upclose viewing, but it allows you to "pull" in more of the peripheral vision. It is almost as if you are bowing the video to get the far left, and the far right. Yeah, I noticed that everything looks farther than it is. I'm try to get as much coverage as possible, i'll probably have to another camera then. I have been loooking at lot of the postings concerning video quality. A lot of them mention Jpeg2000 compression being one of the best for good video. I'm going to a little more research on it. Thanks for your help, -Rod-

The variables come with brand name, quantity built, and distribution. Yeah I thought I was buying a good brand name DVR, Ganz is made by CBC an American Co. though the DVR is made in Korea. I am really surprised that you are having blockyness of video. I have rarely seen this event in present day. It was very common a few years ago. You would find this in a $250 DVR at the "club" warehouse. It was very blocky video due to it compression ratio. [/b]Hmmm, Maybe this Ganz,Model has not been updated in a long time or is a old one , I need to look at the production date. Do you have to record at 704 X 480? If you change the setting down a little will it remove the blockiness? I did try the lower resolutions and that did reduce that blocky mosaic effect, the vidio looked smoother, but a person standing 20-30 ft. from the camera was fuzzy. I would say if you are in the market for a good DVR then go to a company that has a show room in your area Thanks, I'll see if I can find one in the phone book. Could you recommend a Name brand or model if I can't find a local dealer?

I'm using KT&C Brand Bullet camera's with 3.6 mm len's. They use a Sony EX-View Sensor. 600 lines resolution. For wire I have siamese power and video cables, not sure what brand they are but they are the waterproof type. No motion the camera's are just pointed at stationary objects. The thing that surprised me was the video quality was not as good with the Ganz which cost me close to $1000 VS the HI-Sharp I paid about $200-$300 for. The DVR you recommended has H.264 Compression, Is the video any better than Mpeg 4? I like the DVR you had a link to but It only does 60 frames per machine I would need one with at least 120.
