1080 HD, approx 10 metres to the gate and then beyond that there is another area which is a further 10 metres, maybe a 40 degree angle as its postioned on my second storey which is above the 10 feet maximum as I have only two options, less than 7 feet or about 12 feet.
The strange thing is it will pick cars up on the road which is beyond the lower area, so that would be approx 25 metres.
I tested it a lot with the family and it never picked anyone up coming through the gate. Then our friends arrived (three of them) and it picked them up coming through the gate but not when the left at night.
