| I have purchased 2 wireless cams, the first one was much like what you have now. It transmits on 1.2ghz, was a very small cube size, and I could get maybe 50 feet out of it before it died. I have since read that many of the 1.2ghz cameras are like this, that the transmitting on that freq. is a clue that they are the low end systems. The other clue was that the receiver has a pot for tuning in the camera, it isn't set to a single, stable freq. I'm not too dissapointed though, I only paid $50 for it (think I might use it as a rear view in my van  ).
The 2nd camera I bought is 2.4ghz, and is more like the size of a shrunken lipstick cam. It is a bit under 2" in length, and the receiver has 4 selectable (and specific) channels it will work on. I paid about $110 for this one, though it isn't exactly what was advertised on the website and I still haven't heard back from them about why this is (they have a bunch of pictures of what it looks like you are buying, but that isn't what I recieved). Out of the box this one would go about 100-200 feet, with some static and breakup. I have since added a 6dBi directional antenna to the reciever, and can now get between 500-600 feet before static and breakup occurs. I plan on getting an even higher gain antenna (probably a 14dBi for about $50), and am thinking about opening up the camera itself to put at least a longer wire, if not a high gain omni on it as well. I hope to get up to 1000 feet with the better antenna on the reciever.
Currently I'm only using it on my plane, and it was just behind the motor mounted with a thin piece of soft plastic. It's not very stable of a mount, the few videos I've done so far have so much bounce it would make a seasoned flyer naucious! |
I ended up loosing it in the wind coming down hard...I proke a blade! But that was about it......I needed to go back home and dig out that wreless thing again!
It allows me to go out for about a good 300 meter (about 1000ft.) before it starts goofing off. And trust me, the corona probably turns into a dot LONG before you get to the end of the cam range.
