Access control systems are designed to regulate and manage the movement of people. One of the essential components of access control systems is the portal, which refers to a physical barrier that controls entry and exit from one space to another. The portal is typically a door, gate, or hatch that is managed by a locking device like a key, code, card, or biometric authentication that grants access. The locking device may also have additional features, such as integration with video surveillance systems or intrusion alarm systems for a more intelligent security system. In addition to managing access, portals can also be used to monitor and record the movement of people whose historical records can be accessed from DGAConnect.

Bluetooth is a technology standard for the short-range wireless interconnection of mobile phones, computers, and other electronic devices. One type of Bluetooth technology that consumes significantly less power is called Bluetooth Low Energy (BLE). This type of Bluetooth remains in sleep mode unless a connection is initiated, which translates to much longer battery life. This is ideal for access control systems since it doesn't use as much power. BLE is the wireless technology used in mobile app-based access credential systems.

Intrusion Alarms

When it comes to door/window contact sensors used in business security systems, the most common mistake we see is either overuse or underuse of these devices. Sometimes we see a contact sensor installed on every door and window regardless of location – which likely increased the installation cost without adding additional security benefit. Other times, we see doors and windows that are easily accessible from the outside missing a contact sensor, making the business vulnerable to potential intrusion attempts.

When we are designing business security systems, we sometimes get pushback from clients about whether they really need motion sensors in addition to door/window contacts. At other times, we get pushback from our clients’ architect who asks us: “Do we really need a motion sensor in that spot? Can you move it to a more hidden location?”

Modern electronic glass break sensors are smart devices that are highly effective at detecting a breaking glass window. But the truth is glass break sensors can be tricky in a business security alarm system. High-pitched noises from outside can cause false alarms. Furthermore, some glass window types don’t shatter in a way that can be picked up reliably by these sensors.
