SX20, extending the camera cable

Hi

I have project where I would like to use the SX20 codec, due to it being having multisite at an affordable price. But locating the codec and camera together is not an option for this installation. So I need to extend the camera cable,Picture attached.

I am thinking of ordering the following gear:    SX20 Codec,

                                                                 PrecisionHD Camera 1080P12x (not the new SX20 camera), Picture attached.

                                                                 Power supply PSU-CAM-V and cat6 shielded POE injector camera extension kit CAB-PHD-EXTR

My theory here is to inject power via the camera's power supply over the Cat6 cable with the POE unit on it, to enable a longer control cable run. Then use a Kramer PT10Hxl HDMI extender to handle the video signal.

Would this work? Or does anyone know of a CISCO endorsed method/manual on how exactly to do this

Kind regards

SX20, extending the camera cable

Hi Chris,

This is something which is not tested by cisco, however you can go ahead and try this.

the extender kiet cable will work with a regular 12x camera with a power supply.

you can try and update.

or else you can go ahead and make a cable

CAB-HDMI-PHD12XS=

using the pinouts you have to in order to use the supplied camera with a SX20.

Regarding lengths - the cables we provide are 3 meters long.  When an  integrator makes their own extensions, they need to observe normal rules  for RS-232, power, and digital video.  For example:

Any camera  control cable that is longer than 5 meters, should not connect the 12V+  pin, and the camera should be powered locally with PSU-CAM-V=

The  control signal is Visca, which uses RS-232 at a baud rate of 9600.  With  care and large enough gauge cable (e.g. 22/4 shielded audio cable), the  signal can be run 75 to 100 feet.

Digital video is not friendly to  long cable runs (with the exception of HD-SDI).  So for cable runs  longer than 15 feet, either very high quality cable needs to be used, or  repeaters of some type, or extenders based on UTP or fiber.

hope that helps

Regards

Ravi

Re: SX20, extending the camera cable

Hi

Thank you very much for the quick reply. I am going the cable kit and PSU route will update when installation happens.

FYI I will be using this forum a lot! And recommend it to all the people in my company.

Re: SX20, extending the camera cable

Have your tried to extend the  camera cables on the SX20, if so did it work.

Hi

No not yet the install will only happen in about a month. Will keep you updated. Ravi I hope your plan works!

SX20, extending the camera cable

We have purchased a number of SX20 packages with the 4x cameras and have discovered that at a couple of sites the supplied 3m custom cable is not long enough.

Am I correct in thinking that Cisco have chosen not tto make these cables in longer lengths? (happy to be told otherwise on this)

What are my options bearing in mind that I am no good with a soldering iron?

SX20, extending the camera cable

Hi Richard,

As of now now extended cables provided by cisco.

once main reason could be that these devices are qucikset devices and not the integrator packages.

not made for such large divisions , in order to get optimal from the device.

on the other hand there are other ways as mentioned already in the thread.

Thanks

Ravi

Re: SX20, extending the camera cable

Hi all

We have just completed the installation mentioned in my original post. It worked and its very easy!
Order you SX20 with the 12X zoom camera. You will get a camera cable that has the new propriety camera cable: (HDMI and control) to a separate HDMI and control cable. Use standard HDMI extenders (Kramer) and RJ45 female to female barrels.
Today at the office we extended the control cable 25m, and it works.
Thanks for all the help.
Chris

SX20, extending the camera cable

We just installed our SX20 yesturday and had the camera 80ft away from the Codec. We used a TRULINK HDMI over CAT5e Extender, Model 40477 (except we used CAT6). Works like a charm and picture is beautiful. The camera cable that comes with the system stays with the codec as it has a proprietary end and then use regular CAT and HDMI cable at the camera. You do need to run 2 CAT cables for every 1 HDMI cable though, so you would need 5 all together, 2 for camera to codec, 2 for codec to TV and then 1 for camera control.

If you want more detail please let me know.

Re:SX20, extending the camera cable

Hi Curtis,

What is the camera model 4x or 12x

Thanks

Re: SX20, extending the camera cable

Yes. Sending the content through the HDMI extenders over Cat6 for 75 feet is the as not even using the extenders over a shirt distance. No video or audio issues from both camera or tv.

SX20, extending the camera cable

I am planning for a similar setup.   The camera will be about 120' from the codec.  I plan to use HDSDI to run the video signal back to the C90.  For the camera control, there will be a 125' cat5 cable acting as an extention.  Do you see any issues with camera control at this distance?

I plan to plug in the camera power brick, will that cause any issues?

Thanks
Dan

SX20, extending the camera cable

Hi Dan,

You will have to use a separate power brick as the control cable would not be able to provide required power

rest all should be fine as you will be using HDSDI

Thanks

Re: SX20, extending the camera cable

Has anyone been able to extend the 4x camera?

As far as I can tell from the "PrecisionHD Camera User Guide" (http://www.cisco.com/en/US/docs/telepresence/endpoint/camera/precisionhd/user_guide/precisionhd_1080p-720p_camera_user_guide.pdf), the SX20 camera cable simply integrates RS232 as the separate 5 pins to the right of the HDMI connector fo camera control.

The RS232 would be relatively simply to extend and a 15m HDMI cable will work fine for the video, however, the actual socket on the SX20 and 4x camera may prove difficult to find (obviously the Cisco proprietary plug moulds the two connections into one).

If it is not possible to extend this cable for the 4x camera, we will have to resort to the C20 instead. Tandberg were good on using standards based connectors, its a shame to see that Cisco are resorting to propitiatory connectors again.

Re: SX20, extending the camera cable

Re: SX20, extending the camera cable

Hi Dagerson,

Many thanks for the answers, but unfortunately no cigar this time!

It's not the HDMI part of the cable I need to extend - its the RS232 part. Unfortunately on the SX20, the HDMI and RS232 are combined into a single molded plug. In fact, you can use a standard HDMI cable between CODEC and camera, but the you will loose camera control. The RS232 is the 5 pin to the right of the main HDMI socket. Really what I want is w plug to interface with this part of the socket. Whilst extending the RS232 would normally be reality simple, this is no good if I can't interface with either the CODEC or camera.

The SX 4x camera has the same configuration as the SX20 and does NOT use an RJ45 that the 12x camera uses - otherwise it's all relatively simple as can be seen above.

If you need to know what the camera cable and interface looks like, check out the "PrecisionHD Camera User Guide" (http://www.cisco.com/en/US/docs/telepresence/endpoint/camera/precisionhd/user_guide/precisionhd_1080p-720p_camera_user_guide.pdf),

Re: SX20, extending the camera cable

My apologies, I didn't not see the 2nd part of your post. In this case, I would recommend returning the 4x camera and getting the 12x.

Re: SX20, extending the camera cable

Cheers Dan - but the client is NOT willing to spend the extra on the 12x camera. If the SX 4x camera cannot be extended, then the C20 is the only way to go for us (which does use RJ45 camera control port, and a sensible DB9 socket on the CODEC).

Re: SX20, extending the camera cable

Hi Chris,

You can break out the video and control with the CAB-PHD4XS2-SPLIT= adapter, available from Cisco.  I don't know the price, but I don't think it is very much.  For the 4x SX20 camera you would need two of these (one at each end of the extension).  You would be able to go 10 meters with a CAT5e cable for control.  The camera would need its own power supply (PSU-CAM-V=).  From the posts above, a twisted pair extender should allow you to go further than 10 meters.

I hope that helps.

Re: SX20, extending the camera cable

Yes - very much so. Certainly beets the £2500 for a 12x camera!
