Door Access Control Systems
Access control systems provide authorized individuals safe and secure access in and out of various parts of your business while keeping unauthorized people out. They can range from electronic keypads that secure a single door to large networked systems for multiple buildings. Access Systems also greatly simplify management of your facility: no need to replace lost keys, hunt down old keys from terminated employees, or wonder who has access to which areas.
Stand-Alone Locks as the name implies are an "all-in-one" access control system for a single-door. The lock powered by replaceable internal batteries can be unlocked by keypad, proximity card or a combination. The advantages of stand-alone locks are they can be installed and operational in minutes. Some offer hand-held readers that extract the audit trail from the lock. The disadvantages of stand-alone locks are they are stand-alone and not part of a broader network.
Proximity readers are the most popular option in commercial access control. They are easy to use, and when cards are lost, it is a simple matter to deactivate them and issue new ones. They can also be combined with photo IDs for additional security. Proximity cards, which can work from one inch to three feet from a sensor, are the most common. Because there is no contact between the card and reader, they are very reliable and suffer little wear and tear. They are also inexpensive. A specialized type of proximity card is the automobile tag, which allows access to a parking facility without requiring the driver to open their window or get out of the car. Automobile tags can work at hundreds of feet away from a sensor. Security access systems can use magnetic stripe or barcode cards, as well, and these can be a money‐saving option if you already use one of these technologies for employee ID cards.
Key switches offer electronic auditing through a network while continuing to use a physical key to activate the lock.
Keypads are common for single door security access and less expensive systems. They are easy to use but less secure, since users have a tendency to write down the entry code or to "lend" it to others. They also do not provide detailed audit trails until you provide unique codes to each individual.
Biometric systems rely on physical characteristics of the users for identification such as fingerprints, handprints, or even retinal scans. They are by far the most secure methods of access control. However, they are also considerably more expensive and can seem invasive to employees forced to use them constantly. Early models proved less unreliable outdoors, so they were not recommended for exterior security access.
