Is an SDI Connection the same as av-in ?

SDI = Serial Digital Interface. It is not analog.

Typically, AV-in is a 1/8" analog connection that carries analog composite video and stereo audio over a 5-conductor cable, and it's most often found as a connection on consumer (and some prosumer) camcorders. SDI carries digital video with embedded stereo audio over the same two conductors (signal and ground) and is found on professional cameras, record decks, and monitors. AV-in and SDI are not interchangeable.

Most likely, what you need is an interface that has analog component and composite input connections, along with analog stereo audio inputs. For video, these can be BNC connectors or RCA connectors or even S-Video. For audio, it'll probably be either RCA or XLR, but there may be some interfaces with 1/4" connections as well.

From what source are you wanting to record? That'll help find the right kind of interface.
 
Thank you for the reply...I would like to record just the video signal (audio NO) from this security camera :

EXELON GHN-A955 700 TVL Color Box Camera with 3D DNR, ICR, SENS-UP, DUAL power
that I would like to use to record wild nature videos.
I am going to leave the camera on for many many hours and record animals without disturbing them....

I need a portable video recorder , that supports Composite Video , and that can record in high quality.
There are HD mini dv that have AV IN but they are limited in time to record by the 60 or 80 minutes tapes...I am NOT going to be able to change the tapes every 60-80 minutes. I need to record on hard disk or solid state memory card.
For hte power sourve, it is NOT a problem, I can hook everything up to a battery Car....

Thank you
 
Well, the Hyperdeck Shuttle certainly isn't the device you want for long-duration recording, either. Since it records a very high-bandwidth, uncompressed high definition digital video signal, its recording time on a single SSD is actually shorter than the miniDV decks you described (depending on the capacity of the drive, of course).

Since you are originating with an analog, standard-definition video signal and don't need sound recording, I suggest you look into the long-duration digital video recorders made for the security/surveillance market. It's possible to get hundreds of hours of recording capacity for $500 - $800 or so. The only downside is that these usually require AC power, but a car battery plus a small inverter ($40 or so at Radio Shack) will probably work fine for that.

The problem is that these devices record in low bit-rate....I need something in minidv quality....I am really not sure about these security systems recorders..do u have ay other solution please ?

Thank you
 
You don't mention budget at all, so I'm not sure how much you can spend on this. In general, you've got some conflicting requirements (high quality + long record time) that will tend to drive the cost up. You could use a kipro, and it can take analog input, record for a long time at a very nice quality, however it costs about $4,000. If you don't have to use the security cameras you have you could use something like a gopro and get a good number of hours of recording (and high quality) from it (it's also waterproof) for about $300.
 
I have another idea....what about buying :

1) a Maxell iVDR Xtreme

2) an hard disk for the Maxell iVDR Xtreme

3) conncet it to a HD minidv tape camcorder (that has an AV-IN) which I have

The idea is to connect the camera (cctv camera) to the HD minidv tape camcorder, which is connected to the Maxell iVDR Xtreme , so that the video footages are recorder to the Maxell iVDR Xtreme through the minidv AV-IN camcorder

Would something like the above work ?

Thank you
 
any signal input into the iVDR must be firewire not analog. (you need an analog to 1394 convert if you went that route.)
Try looking into a Fast Forward Video Digideck or Omega HD and place the largest compatible HDD into it.
 
Hi guys, it seemsthat now there is a adapter cable to use with the HyperDeck Shuttle to convert the video recorder's DIN 1.0/2.3 HD-SDI connector to accept a much more common BNC connector.

So I guess the HyperDeck Shuttle can be used to record both

- digital signal / HDMI

- analog signal / AV

My question is, how much minutes of video can be recorded on a 250GB - 2.5" SATA SSD Drives ?

thank you
 
There is no adapter "cable" that will convert Composite to SDI. What you probably saw was a cable that converted the DIN to BNC still needs to be a SDI signal though. You can buy adapters to do that (around $300 - analog to SDI - http://www.blackmagic-design.com/products/miniconverters/ ) but even if you went that way recording uncompressed SD NTSC video would only get you just over 3 hours on a 250gb drive. Uncompressed is NOT what you want for something like this.
