Drivers for USB Webcam NHJ? Dual-Mode DSC(2770)



G'day,

I have recently purchased, well closer to given but in lew of services
rendered, a cheap digital USB pencam / webcam. I noticed that dick smith sell
a very similar product on sale at the moment for $58. It works ok in
windows xp, but I spend most if not nearly all my time in linux and am
slowly searching the web in my free time for drivers, or technical
information on this product. I would appreciate any assistence or
information anyone else might be able to give me.

Its not bad in quality for a cheap / free cam.
http://www.vicomte.tk/ - "my webcam" link or
http://alphadimensions.net/~vic/webcam.php

The box I got it in was a very simple unremarkable blue box which
contained no real pertinant information, least of all a manufacturer or
part number/ID code. It mentions a number of times the camera is a
"Dual-Mode DSC(2770)". The manual was in very poor english and didn't
aid in identification of the camera either except for mentioning at the
bottom the code "CD30P".

I believe it is a Mitek CD30P, it certainly has the same specs, but as
to the real manufacturer who knows. I think it could be NHJapan aka NHJ.

I opened the camera up and the best information I could get from the
chip when I slowly peeled away the glue holding the speaker on was as
follows;

|_|_|_|_|_|
| |
- SOLUTION -
| |
- S5SV6416 -
| |
- 2B23 T2F -
| _ _ _ _ _ |
| | | | | |

The PCB has written on it under the USB(A) Female connector;

CD30P(04)
2002/11/23

I am using linux kernel 2.4.20 on debian 3.0r1 upgraded to latest
'unstable' packages (which usually to me are quite stable).


From dmesg I also gained upon plugging in the Camera;

hub.c: new USB device 00:11.3-1, assigned address 2
usb.c: USB device 2 (vend/prod 0x2770/0x9120) is not claimed by any
active driver.

From some searching of the net I believe that the people responsable for
this vendor id are a company called NHJ. I can't read any japanese
though, so going to http://www.nhjapan.com/ doesn't do me too many
favours. Just looking at the images (http://www.rakuten.ne.jp/gold/nhj/)
shows me that the particular camera I have is not there, but I believe
it could be the same parts or components that are included in their
"che-ez!Moni-Me or Snap".

Some Pertinant links;
http://www.mitek.com.tw/2ndround/dcam/cd10p.htm
My camera.

http://www.aiptek.com.tw/english/pro...m/pencam1.html
A very similar looking camera, different chipset I believe.

http://www.dolphinfast.com/products/1007.html
Possibly a rebadged aiptek camera?

http://www.rakuten.ne.jp/gold/nhj/
The camera's components original creators ?

http://www.nhjapan.com/

I was hopeing that there might be some people who have encountered
similar problems or have been considering getting their particular
webcam devices to work under linux, and/or have been succesful in
setting up their camera. If anyone could help me out here, it would be
greatly appreciated.

Kind Regards,

Post Little Silver PenCam...

The little pen cam I have is a DigiCam Trio DSC-2770. It looks to be the size of about two marking pens. It has a round eye frame at the top, and on the fromt a black round disc with the camera lens in it.

It runs on 2 'AAA' batteries, and has a tri-pod style base. It sits in a little sleeve that mounts onto the base. The USB socket is in the upper two whirds of the body, on the left side, when facing in front of the cam.

On the top right, is the 'shutter' button, and below that on the back, is the power/feature select button.

The box is mostly white, with a blue stripe, and like yous it is un-remarkable. As for the low quality of the documentation... The cam came with 2 CD-ROM's. Drivers and software, and a paint program.

Not bad for a low cost camera though...

Sounds like the same camera as mine, looking around I have found it is a very popular camera, or atleast the DSC 2770 is. Many camera's with many different brands and makes and models seem to run this camera's components.

This only makes me more interested in finding drivers for it for linux.

http://www.concordcam.com/support/fa...sytoo_spec.htm seems to be another one.

So far I know of about 8 or 9 camera's widely sold with these components, it is somewhat surprising no one has looked into driver support for them before.

I wonder if drivers from another camera model would work on it, or with it?...

Do you know off hand, if the Linux driver base has any kind of a driver for a USB camera?...

Do you run the console mode of Linux? Or do you run the X/Windows interface? The reason I ask, is supposedly the X/Win software should be able to use the Win32 based drivers, or so I have heard...

The linux kernel has support for a number of camera's which can be compiled in to the kernel or added through a module. The most similar camera but one which is not supporting ours is the STV-680 based camera's.

Their project website is based at sourceforge here;
http://sourceforge.net/projects/stv0680-usb/

There is also support for Phillips cameras and logitech and others.
http://www.smcc.demon.nl/webcam/

Software available as front ends for the drivers include xawtv which I run for my tv card, but also those listed here;
http://www.smcc.demon.nl/webcam/working.html
There are many more.

As for our camera, here are some other camera's which use the same chipset which can be found around the place.

Che-ez Snap

As for me, I run Debian linux with an XFree86 interface on my main machine. I run the console mode on my other machine which is primarily an e-mail and webserver.

Well, in looking around I have found more sites that seem to be selling this little cam, and it does appear t obe very popular indeed. But, like yourself, I have yet to arrive at a web site that carries anything specific in the way of either technical documentation, drivers or any further software to use or operate with the cam. The software that comes with the cam, can capture. But NOT stream any video or images onto the internet.

In order to post the images my cam sees, I had to go and get a shareware program to do the wbcast...

I am continuing to look for more on this, and if I find anything I will be certain to let you know...

Oh, I found that the DigiCam Trio (DSC-2770) is also sold as the Aiptech ProCam Trio...

Screw Shareware!! Freeware, Http://www.booru.net/ Little app, seems to do the webcam, ftp thing fine, no probs, and its FREE!! :P

Dunno about the streaming thing though, you probably want a cam which has more skillz then this one for that.

Most of the Aiptech listed camera's are STV0680 chipset based, it would be odd for them to have one like ours non-stv0680 based. Maybe they found the STV0680 chipset better then the 2770 one. *shrug* no idea.

My camera is a dead ringer for the Aiptek pencam1. But from what I can see the pencam they use is the STV0680 chip and not mine, or yours.
http://www.aiptek.com.tw/english/pro...m/pencam1.html

But you're saying their procam trio is a 9120/2770 camera ? where did you find that info out ? Got a URL or something you could send us ?
http://www.aiptek.com/products/pencams/trio-vga.htm ??? this the one ? looks like my cam, similar stats, but which chip does it use ?

Post Was not hard to find...

I got my DigiCam Trio (DSC-2770) from: Click Here!

I don't know what chipset the Aiptech has, but I am assuming it will be something very similar to mine or yours...

I did notice though, that all of the camera models, do look very similar...

Another Dead End, the Aiptek Pencam Trio is (vendor 0x553, product 0x202).

Not the vendor and product id we want.

There is a driver in development for this camera, its called sq905 in
libgphoto2.

What is the content of /proc/bus/usb/devices for this camera?

The Sony should work though, yes.

Check out the current CVS version, and contact
Theodore Kilgore <kilgota@auburn.edu> for info.

Download a current CVS snapshot I just put up for you from:

http://www.lst.de/~mm/libgphoto2-2.1.2dev12.tar.gz

Ciao, Marcus


Well seems there was truth to the previous post I put up of;

"There is a suggestion the chip used is similar to this one;
http://www.sq.com.tw/products/pdf/dsc/SQ905Spec.pdf
Here
http://www.teaser.fr/~hfiguiere/linux/digicam.html"

Oh well, its all good then, I think we can give this guy "Theodore Kilgore <kilgota@auburn.edu>" some help with our own testing of his drivers and give him feedback, as it seems we're definately a minority here amongst the big name camera's and he may need the best help he can get when it comes to beta testing his drivers.

I got my Vendor 2770 Product 9120 Camera working

My camera is cheap and nasty. Its simply called Mini Digital Camera.

/proc/bus/usb/devices has:
Quote:
...
P: Vendor=2770 ProdID=9120 Rev= 1.00
S: Product=USB DIGITAL STILL CAMERA
...
On Mandrake 10.0 .. I installed gPhoto2
Quote:
urpmi gphoto2
and then did:
Quote:
gphoto2 --camera=STV0680 --get-all-files
this dumped the pics into the curent directory.

There is also a GUI front end for gphoto2 called 'gtkam'.

Hey guys, have a look at the sqcam driver http://sqcam.sourceforge.net/.

I can confirm that this does work as a webcam with my "argus dc-1510" cam.

However kopete doesn't like it much, green output, very slow update etc.
