Dennard 2060 - gv800 ????

[jody 0]

Hello, Im new to cctv systems and need some advice if possible.

 

Im currently having some vandal damage to my vehicles on my driveway (day/night), so Im after getting a good ptz camera and a dvr card setup.

 

Ive been reading a little into it and have come to the conclusion that a dennard 2060 dome camera looks like it would be a good choice together with a geovision gv800 card. Could you please give me your opinions?

 

I have seen several used cameras on ebay but I am unsure as to what i will need exactly, will i just need the camera, dvr card and cables?

 

I need the camera for evidence collection, so your suggestions on other good setups are appreciated, I do have a limited budget of around £600.00-£700.00 but if I can do it for less that would be good.

 

Many thanks in advance for your help.

Domes like that are not going to be easy if you are new to cctv, they are not just like a normal camera where you power it up and it works...

 

If you get a 2060 or similar on ebay, watch out for the following points.

 

Make sure its a outdoor model, not the indoor one.

Make sure its a day/night model if night time viewing is needed, some are day only I think.

Make sure it comes with the correct dennard power supply box and cables.

Make sure it comes with, or you are able to obtain the correct mounting brackets etc, they are specific to the domes, and not easy to get hold of cheaply.

Make sure it comes with any required cables, sometimes domes/controllers etc use expensive connectors that are not available at local diy stores, and cost money from specialist suppliers. This may not be a problem, not sure what connectors that dome uses, worth checking with the seller though.

 

Make the seller offers a warranty, and its the dome is not badly scratched, many sellers sell domes with damaged dome covers and say "easy to replace" or similar. Easy to replace they may be, IF you can get hold of one without spending a small fortune that is.

 

As for using it with a geo card, firstly to have any chance at all, you would need to make sure you get a model that has rs485 control (some of them ONLY accept up-the-coax control, which is no good for geo without spending even more on converters)

 

Next you would then have to have a rs232 to rs485 converter, plenty on ebay, and I think you can even get a one from geo.

 

(alternatively, if using a dedicated dome controller say one of the tx range of keyboards/matrixes then those should be able to be controlled via a normal serial port, and will allow even the up-the-coax domes to be moved around. I dont have a dome, but do controll a telemetry board to a pan/tilt/zoom via this method, and through that to geo.)

 

Finally, you would need then to make sure you can connect it all up, domes are not for the inexperienced, unless you are prepared to do a lot of learning/research.

 

Next assuming its connected properly, power, comms etc you would need to get geo talking to the dome. This means the protocol the dome uses must be one geo can support. Not sure what protocol those domes use of the top of my head, but I would look into that before going any futher, or it just wont work if geo cant talk in the same language as the dome talks.

 

You could if you are cabable, alter geo to support a different protocol to some extent, I did that for my ptz, but its not a task I would recommend unless you know what you are doing in that area.

 

Then the dome needs installing, all connecters weather sealed etc, earthing where needed, and suitable safety precautions taken where the mains is on the psu.

 

You may also need additional lighting, if its going to be looking around on dark nights.

 

Personally, I would get a couple of fixed cameras, a lot easier to install, a lot less likely that you will run into (possible massive) additional costs to get something working, and quite a lot cheaper. But if you want to go the dome route, at least you have a few points to look into before jumping in.

 

Good luck!

Thank you very much for your reply, it will give me plenty to be getting on with. It looks like I have a lot more to learn, Im sticking with the dome idea I think as i wish to keep my eye on local gangs which pass my property often at night. Can you reccomend an installer in the grimsby locality?

 

Kind regards Jody

hi mate. to start with i dont know much about the geovision gv 800. i guess you want a dome & to record it on your pc. i know everything about the dennard dome. i think your best choice would be to buy a controller to control the dome & just record the video on your pc. you could look for a bbv dtx400dc which is a 1 to 1 keyboard. you connect the coax from your dome in to the keyboard. you would then need to take the output from the keyboard into your pc. the connector type from the output is a bnc. so whatever pc video input you have you need to convert the bmc to that. there cheap im sure.
