I ride my horse in an arena that is not visible from our house. It is about 400 feet away up a hill. I'd like for my husband to be able to check on me via a camera so that he would know if I fall and can't move due to injury, which happened 2 years ago. We could use a smartphone or some other device to view. Something either battery or solar powered would be best since I'm not sure we can get power there. The system does not need to record video. It only needs to display video while I'm there, which is normally no more than 1 hour. It would need to be an outdoor unit with a wide angle. I saw a pet monitor system by Motorola (Scout) that had everything I wanted, but it requires electricity. I do NOT want it to be motion sensitive since the lack of motion is the issue! Does anyone have a suggestion for a setup that would work? Many thanks, Stacey
