I have a question regarding a PTZ camera. The camera and the Geovision capture card support Pelco P 9600 baud protocol.I purchased a RS485 to RS232 converter on Ebay that claims it needs no additional power. So I have 2 wires connected to the RS 485 converter and 2 wires connected to the camera. I have switched the wires to verify they were not crossed.I tried setting the camera and capture card to Pelco D 2400 baud with the same results no control of the camera. When I power the camera off and back on it will go through all 4 axis extremes and park I think at a home position.When I hit the zoom and direction keys on the PTZ keys through the Geovision card I can see white interference lines in the camera video like it is sending some signal but no response to input. Is there something I need to do to the com 1 port on the computer or are the default settings for com1 sufficient? Could it be the RS 485 to RS 232 converter needs some power?On the adapter there is connectors for the 485 plus and the 485 negative connectors along with a 5plus connector and a ground.Any ideas would be greatly appreciated.Thank-you

In regards to PM I am aware of the external box and the internal pc card. What is your preference? Thanks PM sitting in outbox unable to send. Here is my contact for response. tthompson30@wi.rr.com

Get a GV-NET RS485 to RS232 box or board and eliminate that Ebay part. No need for it. Within 5 minutes you will have the problem fixed and be controlling your camera correctly. If you need a module, I have some and I can sell you one. They are very inexpensive and work. How can you be so sure this will solve my problem? Please inform how much and how I can order because as is the camera is worthless to me.Thanks

Does anyone have any suggestions on where to buy some InfraRed light emitters to supplement my black and white cameras? The longest distance is about 25 feet.

I have done a lot of research on CCTV cameras in the 250.00 and less category and am looking for input on preference of black and white or color. I am leaning towards Pelco or Sony for my choice I just don't know if I should purchase an entry level black and white 330 lines of resolution or step up to 570 lines of resolution, or should I purchase color and get less low light capability? The high end Pelco/sony has an auto iris varifocal lenses and I am told these will vastly exceed bullet style cameras for quality. What lux rating will get me close to dark interior with out IR led's?. The entry black and white goes for 130 with lenses and high end black and white 230.00 with high end color at 260.00. I will be using a Geovision 16 camera card the 480 frame G1000 unit. I will be purchasing 12 or so the total cost fluctuates 1000 to 1800 dollars. I could go entry level thinking in 5 years today’s technology will be obsolete or shoot for higher end at the present. I am just looking for input from any one who has used these types of cameras and what their preference would be. Any input is most appreciated.

Well it looks like Pat shut Rory down but what about my camera selection. I need you 3 or so experts to give me your opinion on the Pelco MC 3600H-2 for around 240.00 with a varifocal lens. These are in a house with low lighting and I will compromise the color to get a decent monochrome camera. The Pelco is asthetically pleasing for a C/CS camera and has a 5 year warranty.ftp://www.pelco.com/ProductSpecs/21982.PDF is this a decent camera or what would be a viable solution.

I am just looking for input from any one who has used these types of cameras and what their preference would be. Any input is most appreciated. There will be 12 cameras in separate rooms in a house. I would prefer the cameras to function in extremely low light. I also will have 2 outside with 1 in the garage and 1 at the front door. I plan on using the pelco dual heated case for these two cameras. Another factor is the distance from the camera to the object or window will range from 10 to 25 feet. My question here is will the 2.8 to 12 mm varifocal lense work or should I go with exact mm lenses for this application. I really like the Pelco CM3600H-2 monochrome for 165.00 plus the cost of a auto iris lens,preferably 2.8 to 12 mm focal length.Please let me know your thoughts on this product. ftp://www.pelco.com/ProductSpecs/21982.PDF
