Unlike traditional analog cameras that rely on physical cables to transmit video signals, IP (Internet Protocol) cameras send data over a local private network or the internet to be stored on an intelligent video server. Some applications employ cloud storage of video events, allowing users to access and review footage from anywhere (as with DGA's OneVIEW). These cameras also have higher video resolution and more advanced features like video analytics, making them a popular choice for businesses and organizations of all sizes.

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.

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.

This is why Door Held Open Alerts were created. This feature is part of an advanced physical access control system.

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.

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.
