i have a sentient h264 ptz dvr and a vcl orb0006(honeywell i believe) and am having trouble connecting them.

on the back of my dvr the interface has these connctions "+5,gnd,485b,485a,gnd,1no,1nc,gnd"

on the cctv camera i have "s.gnd,sync,data-,data+,0vs,+vs,vgnd,video,0vh,+vh"

according to the book on the dvr(lacking in detail to say the least!!) it supports rs232 and rs485.

i have established that the 0vs and +vs on camera are a 12v supply and the vgnd and video are the videio line.

i have connected these and have a picture, but am unable to get the PTZ side to work.

any help is greatly appreciated.

thanks

you need to connect the data lines

so far you have power and signal not PTZ

so 3 pairs in total,

Does your dvr support vcl protocol?

so far i have power and signal, its just the ptz that i cant get to respond.

in the camera i have changes a dip switch which i am lead to believe has changed the protocol to pelco-d,

the dvr only supports pelco-p and d.

thaks

sorry, what do i connect the data +/- to??

I think you will find 485A/+, 485B/-

VCL domes are 24vAC

If memory serves me well (as if) the bank of 4 dips the factory default is 0000 I think you need 0100 or vice/versa.

does your dvr look like this .... if so it does not support a ptz. you will need a controller.

hi, that pic is exactly what my dvr looks like and in the book it says it does support rs232/485 for ptz. in the menus i can set up protocol, address,baud etc for each channel.

i have linked the data+/- to the 485a/b with no response at all. the bank of 4 dips is how i have them set, this as far as i know is pelco-d.

Are all domes 24vac? mine appears to be working fine on 12vdc, would it still work?

thanks for your time people!!
