OtO was built with both hardware and software security in mind.
Each OtO unit has a steel and aluminum frame that can lock the device to a permanent structure using a chain or cable and lock.
Note the widest part of the loop is 3/8".
In addition, each OtO unit is securely programmed to a single login and password. If someone steals your OtO device, it won’t work unless they know the login and password information.
