How to convert HD-SDI to HDMI?

Many HD broadcasting cameras are pushing out a HD-SDI signal that needs to be viewed using a HDMI connection on the other end. You'll need a HD-SDI to HDMI convertor, these converters are compliant with the Society of Motion Picture and Television Engineers (SMPTE) standard of 292M and 296M. These standards support data rates up to 1.485 Gb/s.

Everfocus model number EHA-SRX is capable of receiving HD-SDI digital video signal up to 1920x1080 resolution over 75ohm coax cable. This converter will provide a complete solution for the transmission and display of both interlaced and progressive scan HD-SDI digital video. Yes Everfocus is a security camera manufacture but don't worry, this will work for your broadcasting cameras too!

Let's get a look at it from our YouTube Channel



Features:

* Accepts HD-SDI digital video at 720p/60, 1080i/60 and 1080p/30 formats/frame rates

* Processes HD-SDI standard SMPTE 292M and 296M at 1.4585 Gb/s data rate

* Provides standard HDMI output for HD TV monitor display

* Integrated cable equalizer for long distance video transmission without loss of quality

* Capable of receiving HD-CCTV digital video over 75ohm coax cable at distanced over 100 Meters

* High quality digital video and audio transmission with zero latency

Now let's dig into the cable transmission. The EHA-SRX allows a total signal attenuation of up to 43.56 dB along the cable between devices. The actual maximum cable length depends on the attenuation characteristic of the particular cable being used. So if you have a long coax run make sure you have a kick ass quality cable so you have a lower signal attenuation.

I feel like I nailed this blog post, reminded myself of Kirk Lazarus from Tropic Thunder "I don't read the scrip, the scrip reads me."

HD-SDI DVR is perfect for recoding HD brocasting TV Cameras!

I get a phone call from a local television studio looking for a solution to record four Panasonic HDX900 cameras. The catch was we need it to record a HD-SDI signal since that's what the camera output is.

We decided to install the Everfocus EPHD04. Records HD-SDI and real time 30fps.

 

Let's check out some of the features.

* Full HD recording and playback

* Independent HDMI main and VGA call multiplex view monitor outputs

* Two internal hard drives support up to 3TB each

* External HDD array option so you can record up to 18TB

* Control with the front panel, IR remote and optional joystick controller

* Multiple remote access: IE web access, Smart Phone and Tablet live view

* The smart search lets you quickly identify motion in areas of interest from recorded video

My customer was installing this for a Food TV show starring someone with the name of Giada De Laurentiis? I only know of Guy Fieri because people have mention to me "You remind me of that food network star, Guy Fieri."

This HD-SDI DVR worked out great for his TV show application. He did mention this was awesome because, then he talked about a ton of broadcasting lingo that I'm not familiar with but I'm glad it worked out for him. The one thing I do remember is how much he said this was a perfect application for reality TV shows. I think it'll be real cool if I can get that bounty hunter show to order one of these. I am the dog the bounty hunter!

Interested in what else this Bad Boy HD-SDI DVR can do? Check out the manual and data sheet.

Thanks!

Replacing your old CCTV system with HD Cameras? Good idea.

Replacing your old analog cameras with new digital HD cameras should be an easy installation, let's check out the High Definition CCTV Security System.

HD cctv is considered by many as a subset of megapixel and is defined by a specific resolution at specific frame rates with a specific aspect ratio. A camera with more than a million pixels is by definition a megapixel camera. The lowest resolution security camera with a megapixel number is 1.3 and provides 1280 by 1024 pixel resolution and is the 1080P camera.

The 720P HD camera provides images that are 1280 by 720 pixels giving you 921,600 pixels and is short of the 1 million mark, so your 720 high definition camera is not a megapixel camera but many people feel it's close enough so they call it a 1 megapixel camera. If your a installation contractor make sure your customer has a clear understanding of this. I've seen it cause issues with the end user after the installation has been completed.

Traditional analog cctv cameras providing 4CIF resolution offers resolution of 704 by 480 pixels (NTSC) or 704 by 576 (PAL) after the signal has been digitized in a DVR that corresponds to a maximum of 400,000 pixels.

When designing a CCTV system two types of coverage areas get talked about, a wide field view and a detailed specific view. In your wide field view 20 to 30 pixels are enough to represent one foot of a scene. For your detailed specific view of certain images such as cash, face identification, factory assemblies, the demand can rise to over 80 pixels per foot. Here's a cheat sheet I keep on hand just to remind me of what pixel count will fit my field of view best for my location.

Still reading? Good, because I have a about a 30 minute presentation from Everfocus regarding HD cctv. Everfocus is a camera manufacture and has been in business for many years providing solutions for commercial locations. Let see what they have to say.




Now that you know you can use your existing coax cable infrastructure your installation is already half way done! Are these HD cctv security cameras also the same as far as the construction? Yeah! Let's check out a couple from our YouTube Channel.




Here's a look at a HD pan tilt zoom camera.




Don't forget that you will need to also install a High Definition DVR for your new HD cameras. If you only need high definition at a couple of locations such as a cash register, hybrid digital video recorders are available to provide you more security at a more economical price.

Now that you have some knowledge about HD cctv are you ready for six times the resolution over traditional analog cameras. I knew it!
