An access control keypad is a pivotal piece of equipment in any access control system. Keypads are used to restrict and record access to any room, vault, safe, or other area where you don't permit unauthorized entry. Rather than simply locking a door or installing a security chain, the keypad serves as a protective device that will keep your business and its information safe.
How does an access control keypad work?
Keypads are part of a class of security equipment known as keyless access control devices. They are similar to alarm system keypads that you would use for your home or business, except that they are usually attached to a door or other point of entry and typically fastened with metal plates rather than plastic. Some of these devices contain number keys only, while others have slots for insertion of an access card.
Access control keypads restrict access to specific locations by requiring individuals to enter a code. If the code is incorrect, the door will not open, and some can be programmed to sound an alarm. You can purchase these keypads to support both single- and multi-user passwords and codes.
What features are important?
The features you require on an access control keypad will vary depending on what you hope to protect. Consider the locking mechanism when you purchase such a device. They can have single spring latches, which are the most basic models, while others might have five latches or more.
If the keypad will be located in a dark location, or might be used at night, a backlit interface might be most appropriate; if it is located outdoors, it will need proper protection from the cold and rain. You might want to consider a keypad that supports a mechanical key in case of emergencies.
Additionally, some of these devices have timers installed in them, which means you can set different access requirements depending on the time of day. For example, you might want to restrict access entirely at night when no one is at your business, and such a keypad would facilitate that requirement.
How does the keypad work with an access control system?
If you have installed a full access control system for your business, the keypad plays an important role. It can be connected to CCTV (closed-circuit television) monitors, for example, if you'd like video surveillance along with restricted access. It can also be used in conjunction with security measures that protect your business computers.
When you decide to purchase an access control keypad, make sure you request multiple quotes from different manufacturers so you can compare each device on its features and price. Look at key features, such as the material it's made of, the locking mechanism, the password requirements and anything else that might impact your business and its security.
