Commercial buildings often have a solenoid operated door unlock, to allow persons in offices to unlock the main entry doors. Extremely useful in churches and similar!
Our church has part time staff, in an office 100+ feet from the main entrance. Door is kept locked, opened by a pass card. Some systems have intercom to doors, with ability to push a button to fire a solenoid and let the door be unlocked.
We’ve recently set up a host of Wyze cameras for security, including one pointed at the main door to determine who is desiring entrance. The ability to activate the solenoid to open the door from the Wyze app would be great.
