I own both the bullseye and targetvision 1 mile systems - Bullseye AmmoCam Long Range Edition Target Camera

Bullseye Works great at 400 yards and LESS -- It has never worked at great then 400 yds, connectivity problems at greater distances. The unit is back at GSM for repair/replacement. I bought the 1 mile Target Vision... It worked out of the box at 1 mile.. no connectivity issues. If you buy any Bullseye product immediately test your unit at its maximum rated range.. The current software with Bullseye is more sophisticated then the TargetVision stuff but when you cannot connect to the camera ... it doesn't matter. TargetVision's android software appears to match the Bullseye stuff .. hope the iPad and iPhone upgrades comes along quickly. I will report back on the results of the manufacture's warrentee ... will see if Bullseye support their products.
