How do you stream live video from 25 ft away?

Recommended Posts

This is the summary of what we tried to do:

 

1080p HD-SDI cctv camera >>> 25 ft hd-sdi cable >>> HD-SDI-to-HDMI converter >>> 6 foot HDMI cable >>> HDMI monitor

 

I apologize if this is the wrong forum, but I don't know who else to ask.

 

We're not a video company, but our customer requested as part of our equipment package that we provide a live video stream from a cctv camera to an hdmi monitor 25 feet away. The purpose of this is so our customer can install a robot-mounted camera inside a spray booth and transmit the live video to an operator 25 feet away.

 

Seemed like a fairly simple request, but now weeks later we are unable to deliver on it. I'm hoping may be someone here can shed some light on our problem. No matter what we try we keep getting the following error messages on the monitor:

The monitor that our customer has is Dell P2411H, it fully supports 1920 x 1080 60hz. But, to make sure, we have also tried 3 other monitors, including: Samsung SyncMaster PX2370, Asus VE249, and one other. They all support 1920 x 1080, yet all give the same error message as above.

 

The cameras we have tried so far:

 

Q-See QH8005B 1080p SDI Bullet Camera (Grey)

Vitek VTC-BHOCR2812 2MP Outdoor IR HD-SDI Vandal Bullet, 2.8-12mm

GW Security Inc GW788HDSDI Professional 1/3-Inch 2.1 Megapixel CMOS 1080P HD-SDI Outdoor Security Camera with 1920 x 1080 Video Output and Vari-Focal 2.8-12mm Lens

 

All 3 cameras are advertised as 1920 x 1080, HD-SDI cameras.

 

The SDI-to-HDMI converters we have tried so far:

 

Blackmagic Design Mini Converter SDI to HDMI with Embedded Audio

AVUE SDH-R01 SDH-R01 HD-SDI TO HDMI

Lenkeng SDI HD-SDI to HDMI Adapter Converter for Driving HDMI Monitors 1080P

 

All 3 converters are advertised to convert 1920 x 1080 HD-SDI video to HDMI.

 

For cables, we tried different ones just to make sure it wasn't the cable:

 

5 foot Blue BJC High-flex HD SDI patch cable, BNC to BNC

100 foot shielded RG-5U9

 

And of course, we used high quality HDMI cables. Long, short, made no difference.

 

So to summarize:

 

1080p camera that outputs SDI

1080p SDI-to-HDMI converter

1080p HDMI monitor

 

And they never work together. We have tried every conceivable combination of the above, and never got a video. Obviously we're doing something very wrong or very stupid, or both, and any suggestions of what to try would be very welcome.

Have you try using another LCD monitor with HDMI? I have tested my SDI camera with HDMI converter recently at an electrical shop and I notice not all brands LCD can support it.

Yes, I have tried 4 different monitors so far...

Sorry, I don't mean PC monitor & you are not using DVI to HDMI right? Maybe you can bring the cam & the HDMI converter to an electrical shop & test it on the LCD TV.

I don't work with SDI much but would you be better off if you just threw a cheap NVR in there and plugged the HDMI or VGA cable into it? At least it's done and you can invoice and move on...

Thank you everyone for responding, I have finally resolved the issue. If anybody finds this topic on google and is in the same predicament, here is the answer:

 

The frame rate of the camera and monitor must be the same. Most monitors are 60 fps (Hz), while most cameras are actually 30 fps. A regular converter (like any of those listed in topic post) will work only for cameras that output 60 hz (like Orion). If you have a different camera, it probably outputs only 30 fps, and therefore you MUST use a scaler or a converter that accept 30 fps and outputs 60 fps. We have successfully used the following device:

 

AJA AJHDP2Q

HDP2 HD/SD-SDI to DVI-D Video and Audio Converter

 

It is pricey, but works. I have ordered another one that is considerably cheaper, also by AJA, which outputs straight to HDMI. I will report back if this other one works, otherwise it'll have to be the one above.

Joseph, sorry, I completely forgot to mention that you were the guy who PM'ed me the answer! I got so distracted with these cameras, but yes, thank you. If I didn't receive that tip from you I'd still be banging my head against the wall there. Unfortunately I could not try that SDI03 converter you mentioned, because that site did not have an ordering option, and this was something we needed to receive quickly. But I received another one the very next day and everything is working fine now. Thanks again.

this is a good finding. I will try that when I have time.
