How to use

Mount the keypad in a suitable location near the entry point where users can comfortably reach and operate the keys.

Recommendations

Install the keypad at an ergonomic height and protect it from direct exposure to harsh weather when used outdoors; verify that the Dahua system firmware and configuration support external keypads prior to installation.
