We have a customer that purchased 16 solar powered Mobotix M15 camera systems from us 2 years ago for a large building project located near Houston, TX. Their project is completed, they have no further use for this hardware. The solar plants are from Ameresco Solar, each is comprised of a 90w solar array and a 12vdc 110Ah battery bank in a prewired lockable enclosure with Tycon 12-48V power converters, cameras include 64GB SD cards (no wireless comm systems were included). If interested contact me at 541.390.5142 or jeff@radiusvision.com and I'll put you in contact with our customer to discuss details.
