Looking to see if anyone has any recommendations on card readers/locks to secure swinging fence doors entering an athletic complex without the use of hard-wired power. So, we're talking a battery or solar powered reader and lock.
I've seen fence gates secured on boat dock piers, but I believe there was usually a power source handy somewhere nearby.
Imagine a athletic field surrounded by chain link fence with a couple of swinging "doors" that allow you to gain access to the field itself.
Thanks in advance.
