PELCO HELP

[bmac67 0]

Hello All,

 

I currently have a Pelco system at my residence and I want to make a change in the PTZ configuration. I have a question though.

 

First this is what my system consists of.

 

DVR- Pelco DS RealVUE Dekstop

PTZ Controller - Pelco CM9760KBD

1 Spectra IV

3 Spectra III SE's

1 Spectra Mini

3 Sarix IX30c's

and several other fixed dome cameras

 

Everything works great, I currently have the PTZ function directly handled by the 9760, that uses Pelco "P" protocol, my DVR needs only "D". Cameras are direct wired to 9760. I would like to have the function of controlling the Spectra's on the DVR and 9760. I may be missing something and this may be an easy thing to do, but from all my manuals I have read through it looks like I have to decide on one or the other. Can someone point me in the right direction?

 

Thanks in advance.

 

-Mac

You have the CM9760-KBD tied directly to the camera, or is it going through a matrix?

They are directly wired to the keyboard, no matrix.

You have a couple of options. What you need is a "Code Merger" unit.

 

Pelco has its own, the CM9760-DMR (http://www.pelco.com/sites/global/en/products/analog-systems-controls/range-presentation.page?c_filepath=/templatedata/Offer_Presentation/3_Range_Datasheet/data/en/shared/analog_systems_and_controls/cm9760_dmr_data_manager.xml)

 

And Sennetech makes their SCM-200-Pelco (http://www.sennetech.net/Manuals/SCM/scm-pelco-22.pdf).

Survtech beat me to it, you can use a CM9760-DMR device. It allows you to have several input control sources (with different protocols) which can control your PTZ cameras. The control source priority is set on a hardware level (port1 has higher priority, port 2 is the next, etc).

good luck.

Thanks for the help! I will pick up the Pelco unit and give that a try. It will be great to be able to use the new pelco mobile app with the spectra's.

There are a few issues doing it that way, like you do not have functionality of the keyboard on the DS box.

 

Now I know you can use the KBD5000 with DS, and now the KBD300, but I do not know if the USB adapter works on the 9760KBD. You may want to give pelco a quick buzz to find out. This would allow you to hook the keyboard up through a USB port to the DS, and still control your cameras as well as use the keyboard to navigate around the software.

 

I just don't know if the kid works on the 9760

That's not the question. The devices listed allow two RS422 devices to control the same group of PTZs.

 

I'm quite familiar with the possibilities here since I am considering their use in conjunction with a planned VMS replacement which would also eliminate our 9780 matrix switch. Most systems limit the number of analog PTZs that can be controlled to the devices connected to a particular encoder. In the case of the systems we are considering, that limitation would force us to run new control cables for a large percentage of our PTZs (we have almost 200). Dallmeier is the worst offender, requiring each PTZ's control line to be "home run".

 

The only system we have tested so far that would allow us to retain our existing control cable configuration is Genetec, which allows any PTZ to be pointed to a specific encoder's serial port, whether the video is connected to that encoder or not.

 

The Code Merger units would allow us to combine the RS422 outputs of multiple encoders to one control line, limiting the number of additional control lines we would have to run. The possible downside to this method is explained on Sennetech's website - each two-way split adds approximately 8ms of latency. In the case of their SCM-800-Pelco, which "Merges up to EIGHT Pelco RS-422 inputs into a single data line", that would be three splits, or 24ms. That is something we will be testing.

Well first I want to thank you guys for your input on this and second I was wondering if I can get a little more help?

 

I picked up a CM9760-DMR read through the manual and I have a few questions, bear in mind that I am just an end user and I have no expertise in this field but so far I have been pretty happy with what I have for the house. If fact this system I installed was used when we had a guy break into my neighbors pole barn and then broke into my garage. The Pelco cameras picked it all up and the County Police used the footage as evidence and was able to arrest and convict the guy. He was thrown in jail. The police all said this was a top notch camera system and wished all homeowners had something like this as it would make there jobs easier! But the Sarix camera was the one that captured the Plate # on the truck ( Even at 1am ) so for that I am a Pelco guy. I know there may be better stuff, but in my experience so far I have been very happy with the equipment.

 

Sorry for the book there...

 

SO from what I have read it looks like I need to have all the Spectra's set to "D" protocol. As they are currently on "P" Also the Spectra's are direct wired for the PTZ function. So being that they are not daisy chained do I terminate each one? I believe that this how they are set but I will have to get up and take a look.

 

Also I am going to use port 1 correct? The manuals all refer to full blown 9760 matrix systems or older DX7000 or DX8000 recorders. My DS RealVUE has PTZ function built in, unlike the DX that just use a serial port and adapter. Then I have the question on the 9760 keyboard as far as how does that wire into the DMR etc... Basically not wrapping my head around this project yet.

 

Any help would be fantastic! I really appreciate you all taking to the time to help people like me out with this stuff.

 

Thanks again!

No, it works for either protocol (note all cameras must be set for the same protocol). For 'P' protocol settings, see Page 10 of the manual:

 

"DATA MERGER MODE (P PROTOCOL)

In the P protocol, the CM9760-DMR merges PTZ commands from CM9700-CC1 units allowing you to control up to 32 PTZ cameras on one port.

You can set the data manager to operate with two, three, or four CC1 units. To operate the unit in P protocol, set switch 7 on SW6 OFF.

Refer to Figure 4 for connections.

1. Connect up to 32 PTZ cameras to Port 1. Refer to Table A for terminal connections.

2. Connect CM9700-CC1 units to Ports 2-5 of the data manager. You must use RJ-45 reversed cables to make all connections.

3. Set the DIP switches. Refer to Tables B and C. Figure 4 shows optimum switch settings.

a. On SW6, set switch 1 ON if you have two CC1s connected to Ports 2 and 3.

b. On SW6, set switch 2 ON if you have three or four CC1s connected to Ports 2-5.

c. On SW6, set switch 8 ON if you want to give priority control to the CC1 on the lower numbered port.

d. On SW6, set the remaining switches OFF.

4. Connect the supplied AC adapter from the DMR unit and into a wall outlet."

 

Note, replace "CC1" with whatever devices you're using to control the PTZs.

I am going to go back to what I was saying before, rather than buying the DMR you could of picked up a KBD300a.

 

That keyboard will interface directly with the DVR via USB cable. All these wire problems then go away, you still have keyboard function, and you can sort of use the KBD to drive the Control Point software.

 

Just my 2c, seems a lot easier and you gain additional functions.
