Wireless A/V receiver
23.12.2007 0:13
Here's another cute board I could lay my hands on today:
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.
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 http://www.linuxtv.org/v4lwiki/index.php/USBVision_devices
...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.
