Wireless A/V receiver

23.12.2007 0:13

Here's another cute board I could lay my hands on today:

Front Back

This is a 2.4 GHz analog audio/video receiver that connects to a USB 2.0 port (model GP-722, manufacturer unknown). It receives a color video signal from up to four little battery-powered cameras (you know, the kind you see in spy movies or the kind you might put inside a model airplane).

Unfortunately it doesn't work yet under Linux. It uses a Trident TM5600 encoder/USB interface chip, which is a cheaper variant of TM6000. That one seems to have some support under Linux. Maybe I will actually be able to use it after some hacking.

Update: Since a lot of people are looking for it, I've dug out the original driver CD for this hardware and put its contents on-line.

Hello Tomaž,

nice Site! I am from germany and i want to buy also this usb-receiver. I cant find the technical info about the framerate :-( Other products are limited like 640x480 @ 30 fps. Do you have the infos about the videoresolution and the framerate of the GP-722?

Thanking you in advance
Tobias

I think the GP-722 is the same like ZT-721.
U can see the picture of ZT-721 at
http://www.rapserv.com.au/category1155_1.htm

So u can find the linux-driver at

...sorry for my bad english

Hi

GP-722 works with PAL internally - I'm not sure whether the video is transmitted in analogue or digital form, but it is definitely converted to PAL somewhere, since the connection with the computer is an analogue TV tuner chip. So the resolution and FPS are limited by that - you're not going to get more than 720x576 @ 25 fps. The manual also states that the camera sensor has PAL resolution.

I don't think ZT-721 is the same as GP-722 - the page you mention says that it uses NT1003 or NT1004 chipset. GP-722 uses TM5600.

Hello, I've found your webside and I would like ask you for your help. I've bought this reciever with mini camera on eBay. I've receipt also CD with the software (K!TV) and some drivers, but it doesn't work with Win Vista, I have. I've also tried to run it on WinXP. It worked, but only in B&W and the picture qulity was really poor. Could plese help and advice VIsta driver and any working software? I would wery appreciate your help. You can contatc me wia e-mail (libor.plistak@centrum.cz) Thank you very much.

Sorry, I have no idea about Vista driver.

The original software for Windows XP worked correctly in my case - I got color video of reasonable quality on screen. I haven't tried recording it or anything.

The video quality did degrade with distance from the camera to receiver. Try charging the camera battery. I do remember that the reception was better with a full battery.

Jay, that grey one looks exactly like the one I have: GP-723. I noticed that in the pdf at the right is called 722 and at the small picture at the left 723.
Also at the site it says "Complete with Intervideo® DVR software" and the picture shows "Camguard". Sorry, I don't have a Mac.

Hi all!
I have a ZT-721 Receiver but i don't have the miniCD with driver for XP.
I download a Zoran USB TV! Pro Driver but don't work the Audio!!
Unique program that support audio is VirtualDub enabling a Playback audio and setup the "0 Capture Device" driver for Audio device. All other program not found audio with Zoran Driver!
If you have the original driver for ZT-721 or GP-722, please send me from e-mail: info%stefanorussello.it (substitute % with @)
Very very very Thanks in advance!!

Stefano

I have one of these. It stopped working after about two weeks. The camera still transmits something because my wireless internet gets interrupted whenever I plug in the camera, but I get no picture. The software wont even recognize the device. I would be happpy to email you drivers as an attachment if that's even possible.?? -Mike

Nevermind. I can't find my cd now either.

FOUND IT!!!

Great!! Please send me the driver!!
Very Thanks in advance!! ;)

Hello
i need also an driver for vista 64 Bit.

Thanks
Patrick

Could someone please upload the ZT-721 driver to make it available online? I was surprised to find that it was not available anywhere on the 'net. If someone could email it to me, I would be happy to make it publicly available to others.

Thanks,

Don

boo hoo hoo ... also don't have xp drivers for this trident tm5600 chipset based tv tuner card. the cd that has the drivers is damaged :(

Does anyone know if it's possible to use these receivers with the free Dorgem software?

http://www.simplehelp.net/2006/09/27/how-to-use-your-pc-and-webcam-as-a-motion-detecting-and-recording-security-camera/

It does show the Tridvid Capture as device, but can not select the Webcam.
Maybe it's because Windows doesn't see it as a webcam. Is there a way to solve this?

Hello,

I've also one of these GP-722 wireless and a few cameras, working almost fine.
I say almost, because the image I see on the PC is always kinda flashing... :(

Any of you observe this behavior too?
Have you found how to fix it?
Tried to switch of the wireless lan router (which doesn't work anyway with a wireless camera emitting nearby), but it doesn't improve a bit!

BTW, I'm using GP-811T cameras (daylight camera), but it loses the color during the day when luminosity is quite high.
I'd say it works fine for the interiors with fluorescent lights.
And you? Do you observe the same effects?

Sorry, did settings did meanwhile changed to NTSC without notice.
Is now Ok, with PAL_D

Hi Guys,

I have recently downloaded the latest Camguard Home Edition 5.1.14.269 and I cannot get the audio to work. Previous editions worked perfectly and I wish that I had not updated to the latest edition. If I change the device I can get the audio, but the video will not record - a message appears saying "Cannot enable record" If I change the device back, the video records but not the audio.

I have tried to download the new edition again, but it wont install. A message box appears telling "An error occurred while trying to replace the existing file. DeleteFile failed code 5 Access is denied.

I have a ZTV 721 2.4GHz wireless receiver and one camera. I have lost the mini disk that came with the receiver and I want to make sure that everything is still in order. Could someone email it to me please? Alternatively, could someone email me a previous version of Camguard that works for them?

Any help with getting it working again would be very much appreciated.

BeeKay

Well, I found the disk and managed to get rid of a bug in my PC that was stopping Camguard Home Edition 5.1.14.269 from downloading and I now have video and audio; however, I am unable to record. I still get the message "Cannot enable record" but if I switch the device via the Camguard option button, I can record video but no audio.

Has anyone experienced this and is there a fix?

Thanks in advance,

BeeKay

Have an R-723 USB receiver (probably a similar model to GP-723) but can't find any 64-bit drivers (for Vista or Windows7). Anyone come across these or know of a hack?
