Automatic vehicle gates are commonly used to control access into and out of secured areas. Depending on construction, some may also be used to control pedestrian access and egress as well. Guards may manually control access during peak hours.
These vehicle access systems have both residential and commercial applications. Larger homes and gated communities such as custom home parks, apartment and condominium complexes are examples of residential applications. Parking lots (both fee and free based), commercial plants, large business campuses, airports, truck yards, storage facilities, governmental entities, military locations, etc. are business and commercial examples.
