    Hello,

    I was wanting to know if there would be anyone interested in replacement domes for the Geovision GV-SD200 IP PTZ camera. I have a client that need some. Since they are no longer available I designed and printed the rings to work on some off the shelf acrylic domes. I can make them in PLA for $55 or PETG for $65 each. They have brass threaded inserts like the original. The dome is .062 thick molded, not blown. You will have to use your existing rubber gasket and fasteners.

    Thank you,

    Hi,

    I was trying to read the camera with the American Dynamics ADACSNET USB control module. I have two Ultra 7 and one Delta PTZ. I can control the all three with the software. I have updated the module's firm ware. The problem I'm having is that none of the cams send info back. For example if I click on "Flash Rev" I get the response "No Response from Device 1". Also if I ping the camera it just sends nothing pings back. Would that be the PTZ or the Module or software itself? Any help would be appreciated.

     

     

    Thank you,

    Hello Everyone,

    I have an American Dynamics USB CCTV Control Module (ADACSET). It wasn't working so I opened it and noticed that one of the resistors were broken. I am looking for someone that can tell me the resistor value for R51. It sits right behind the two position switch between the Sensornet and RS422 connector. Any help would be greatly appreciated.

     

    Thank you,

    Hello Everyone,

     

    I am trying to compile a list of what Hitachi VK series camera modules are in what brand and model PTZ speed domes. I know what modules are in the American Dynamics/Sensormatic Delta Dome, Ultra 7, Ultra 7E and the Ultra 8. I am trying to find out what the other AD/Sensormatic use as well as Pelco, Vicon & other brands. I am also interested in the same info for the Sony cameras of the same type. Any help would be greatly appreciated. Thank you.

    Hello,

     

    I have a question for Texas Installers. I have a couple friends that would like to have cameras and a DVR installed. One wants it at their house and the other at a small business. I have set up my own system at my residence. Would I need any kind of license to install a system for them legally? I was chatting with a local installer and they mentioned that the requirements changed with in the past 6 months. And they were installing for a month before they knew about it. Who would I contact to find out about obtaining a license if required?

     

    Thank you,

    I am using a Futurlec ATmega8535 controller board for the serial communication. It is all done with software. I freely share the software. As of right now it will control the Zoom, Iris & Focus. I plan on adding a function to turn the IR cut filter on & Off for use with the Hitachi VK-S454R. I made a Interface board that mounts on the back of the camera. It has 4 connectors. Video, Power, Serial & a 9 pin flat cable connector. I also have a half bridge rectifier so power can't be hooked up wrong. I don't think it uses TTL level shifting but I don't know much about that. You can see the photos at Photobucket.

    I think Soundy and I figured you were going to be using a standard PC com port, RS232 data lines are a much higher voltage than the TTL lines inside a device like a PTZ unit typically are.

     

    In looking at the Atmega kit you are using, it has a MAX232 chip that creates standard RS232 voltages from the data lines on the Atmega chip... Of course, if it's working fine that way, we might be wrong... But you might want to check specs, and maybe use data from the lines before the MAX232.... Or maybe, the connector block in your pictures does level converting..

     

    BTW, the bridge for preventing reverse voltage is a good idea, but did you take the 1.2 volt drop into account?

     

    Hi Hardwired,

     

    I'm sorry I missed this post. Anyway, Your right about the RS232 chip. However I am not connected to it. It is connected to one of the other I/O ports of the Micro. The RS232 port is being saved to communicate to an identical board for future use. I am in the middle of creating a web site that will try to explain how I made it all work.

     

    I have found that the cameras work on 9-12v but I have had 13.5v at one point without problems. That was an accident by the way. I don't recommend going over 12vdc. At 12v the 1.2v drop is not an issue.

    Hello Everyone,

     

    First let me say that for me surveillance cameras & equipment is just a hobby. I have a system that consists of 3 American Dynamics PTZ and a Pelco fixed dome. Anyway to get to the point When I first started this hobby I didn't know about counterfeit DVR cards & software. So I unknowingly bought a board with pirated software. I found out when I contacted the manufacturer with technical problems. I ended up purchasing a legal copy of the software. Now I am in the market to upgrade to an 8 port card with hardware compression. My question is Who makes a decent card that is not overly priced like Geovision? Is a hardware compression board better than software? How can you tell if someone is selling a counterfeit? I'm sure there are some legitimate cards on Ebay but how do you know?

    Ok I'm going to try to post a photo again. It is a photo of how I originally interfaced to the camera.

    I removed the surface mounted flat cable connector. I soldered 5 wires directly to the pads on the board where the connector used to be. the other end of the wires go the the DB-9. I cut a hole in the metal case and mounted the DB-9. The mating DB-9 has a RCA jack for video, a power connector and a connector for serial.

    I'm not sure where I should post this so forgive me if it is wrong.

     

    How can I turn on HTML? If I go into my "Profile" it says HTML = Off. Yet the radio button is set to Yes. I have tried to reset, turning HTML to NO then YES and still nothing. Any suggestions? I can't see how but could it be Windows XP x64?

    That board doesn't have the rectifier. http://i739.photobucket.com/albums/xx37/Neptune769/IMG_3472small.jpg try this one. The picture you posted is has a DC -DC converter 12vdc in 5vdc 5amp out and 9vdc 2amp out. It also has a serial connector (2 pin) and a 6 pin for two servos for Pan/Tilt. The small brown cable just below the flat cable is video out. The Atmel chip is a micro-controller that processes commands from the main Atmel micro at the control box.

    I am looking for a working Hitachi VK-S454R (NTSC) camera.

     

    I have for trade or sale 1 working Hitachi VK-S454ER (PAL).

     

    I also have 2 VK-S454ER (PAL) cameras where only the video ouput works. I can't get the serial communication working. If interested I can include service manual in PDF. I have not tried to service cameras. PM for further contact & info.

     

    Thank you,

    I agree with CCTV_Suppliers, firmware doesn't have anything to do with video, it's 'just' for other dome functions and to provide protocol for communication. And I also agree that lens arrangement could cause problems with zoom factor.

     

    Hi dvrtiger,

     

    I think you may have misunderstood my post. I have two American Dynamics speed dome cameras. One is an Ultra VII and the other is a Ultra VIIe. I want to make the VII a VIIe. The only physical difference is the Camera block and firmware. The VII uses a Hitachi VK-S274R camera and the VIIe uses a Hitachi VK-S454R. I have an extra VK-S474R. All I need is the firmware from a VIIe.
