My last forum entry was deleted... at least I can't find it, but here's another try:
Want to get better range from your camera? Try an antenna extension.
I won't say which one (that may be why it was deleted)... but do a search for "Camera Antenna Extension" in Amazon if you might see a selection for one that works with Zmodo.
It costs about $12.99 and works like a charm. So if you have a camera that is a bit out-of-range, try this.
I'm not affiliated with anyone selling these things... just a guy trying to get the most from my camera.
