Photo / Video bank for HD3 / HD7 over USB only.

[Barry Smith]

I dont know if this has been discussed before. Is there a USB technology which performs video transfer onto a personal HDD without a PC ?

I know there are many card readers which can download the contents of a memory card onto a HDD. These are the photo banks.

Any such device for USB streaming ? FTP capture ?

Needs to be a 2.5" HDD device with rechargeable batteries or car charger. Would like to use it with the JVC on the data port.

[Barry Smith]

Is anyone able to confirm whether or not this product will operate sufficiently.

Looks like there is a simple solution.

It would appear that USB-on-the-go is the emerging standard for data trafficking.

Does anyone have experience with a device suitable for JVC ?

Hi Barry, Have been using the XS Bridge 120 (with 160GB disk) for some months now and it downloads from the HD7 perfectly OK and is ideal for covering outside events. The only problem I found was that the small LCD display is not entirely user friendly - it is rather tedious in establishing how much has been copied at any stage - and as a result at one event I lost a large amount of video by deleting from the HD7 before it had been copied onto the XS Bridge.
I now normally connect it via my notebook computer to ensure the copy process is secure - on most events I will be capturing 100GB plus of full-HD video hence the need for an external disk.
Regards
Trevor

Can you explain the procedure? Doesn't the HD7 signal when IT is done with a copy? And how long does it take to copy 10GB?

[Trevor Mattocks]

Hi Steve, The small LCD is the only view of what is on both HD7 and the 'XS Bridge' - and scrolling thru numerous directories can be a lengthy process, especially if the HD7 is full - to check that the copy process has completed successfully.
I cannot recall exactly how the one instance of failure occurred, but the copy process had for some reason stopped mid-process - I do know that it does need a reliable external power supply.

Having a closer look at how many devices have USB-Copy I noted that most of them would not last long on the battery charge to sufficiently allow for the camera copy to complete. Therefore I assumed that field conditions would require a car, a car battery or mains power.

Apart from that I noted that in the world of NAS (network attached storage) Thecus and Synology were two of many who offered download over USB.

Strangely enough, some set-top-boxes also appear to do the same thing. Beyonwiz specification suggests that you could attach your camera to the appliance and surf the contents from a network pc. The only limit is that at this time the CODEC for playing back the video files would only be valid for renamed files, if at all. The idea of camera-appliance downloading is interesting if the playback software works. Normally Beyonwiz comes with 200GB. But it is only one example of many such devices which all do similar things.

For portable use I will test the SAROTECH 2.5" device (OTG version - on the go) as it comes with a car kit for power and supports SATA drives. There is also a hot new 1.8" version which probably will mutate into an OTG device in the future.

For office use I will test the SYNOLOGY or THECUS device as it comes with a USB-TRANSFER function.

For video playback I will look at BEYONWIZ (sic) and SAROTECH devices.

All of these items can be found in google.

You may notice that all TV attached digital playback devices come with FTP (useful) or NDAS (not much fun). To use FTP effectively with these devices I recommend WEBDRIVE software.

This applies to all OS except WebDrive which applies to Windows only. Apple OS X has its own FTP manager.

Interesting TIDBIT I found in my travels. Makes me want to try one.

Think that your NEXTO is only good to backup cameras? Think again.
ND-2325 and ND-2300 now supports back up of the following HDD based Video Cameras :

JVC Everio MicroDrive Series
JVC Everio HDD Series
Sony SR100 series

I heard from the supplier that this week or so they are shipping the SATA version of their product.

It should come in handy with 300GB drives being available.

[Barry Smith]

My ND-2700 just arrived from Next. It has a 320GB SATA drive installed and I will be doing some tests shortly to show how it works.

Apparently this device can backup an Everio camera without a computer using only USB-OTG technology. Should prove useful on long trips.

[Barry Smith]

This has been a very one-sided thread.

Ok..... I bought the latest NEXT Extreme M-2700 series handheld device. I installed a 320GB SATA 2.5" HDD and configured the copy settings for
- AUTO COPY (not MOVE)
- AUTO VERIFY

I connect the 3 inch adapter cable to the USB port of the handheld device (clearly this is a crossover cable for USB). I then use the cameras USB cable into the adaptor of the handheld device.

The JVC then enters USB mode and asks if I want to PLAYBACK or BACKUP as though it were attached to a PC.

The handheld device counts down from 10 and AUTO-SENSES the camera and starts a copy with verify and shows a file progress count.

Really this is a foolproof device. The backup completes itself and the entire camera is copies to the HDD in amazing time (partly because it uses a buffered copy function).

You can then format the HDD of the JVC and keep shooting. I was amazed that it was so simple. It did exactly the same thing to the SDHC cards also.

The limit is 500GB SATA storage in 2.5" technology (at this moment). The price was quite acceptable for this type of technology. Highly recommended.

I performed all functions with a power adaptor attached to the camera and to the HDD. As a device which can be used in the field I would expect that 20GB of shooting can be transferred safely without any need for adaptors as there is a battery in the HDD unit also.
