Communication access control systems are available in a number of varieties including single family units for residential properties, and multi units for businesses. The options available with these include audio systems and video systems. To ensure optimum safety, video cameras can pan and tilt to fully scan the entry area, with infrared illuminating and backlights to see callers in poor lighting.
Other access control systems include swipe card readers, keypad access, keypad and card insert readers and proximity readers. A lockout facility is provided with the keypad access to prevent entry through trial and error of code input.
