Help Needed Asap

[danlad1980]

hi all hope your all well?

need you guys to get your heads around this snag.

hikvision DVR working 3 DM PTZ's with 3 x BBV CTI/1 coax telemertry interface units.

2 of the PTZ work fine as the cable run is RG59 and only 50m long but the 3rd dosn't work due to cable being over 350m long with RG59.

anyone any ideas how i can sort this without changing the cable?

 

Thanks

the video from this camera is working and clear.

They have a working distance of 250 mtrs.

 

One of these will hit 350mtrs    http://www.secure.no/files/Videotec/VID-DTMRX2%20Data%20receiver.pdf

will that change RS485 into coax telemertry?

[Oxo]

Did you read it?

[danlad1980]

reading it now but it reads to me as if R232, 485 or coax all control the outputs and don't send RS485 out on coax?

sorry if im wrong.

Could be a long day is working on me.

 

Samsung Techwin do one that goes to 1km.

No link I`m afraid, just recall it from somewhere.

I assume if BBV can't amplify / repeat , RDT will make something radio based ?

thanks will look into both. thank Oxo, Mr Happy
