Access control is a crucial component of physical security. It is an electronic system that controls the entry or exit of an area. With access control, only authorized personnel are granted entry to restricted areas, which can include a company's main entrance, server rooms, storage areas, and other sensitive locations.

Access Credentials are devices that contain an encoded ID number that can be captured by an access reader. They are an essential component of modern access control systems, providing a convenient and secure way for individuals to gain access to restricted areas. These devices are designed to store and transmit identification data, which is then captured by an access reader. Some of their different forms include cards, fobs, tags, or mobile apps that can be easily carried around. One of the key advantages of access credentials is the range of encoding technologies they utilize. These devices utilize one or more encoding technologies such as proximity, smart card, magnetic stripe, or Wiegand to store and transmit identification data. Proximity technology, for instance, allows individuals to gain access simply by holding their access credential close to the reader, while smart card technology provides enhanced security through the use of encryption and authentication protocols. With the advent of mobile technology, access credentials can now be stored on mobile apps, making them even more convenient and accessible. With DGAPass, you can easily control access levels for each individual user along with schedules. For instance, you could give Employee A access to your retail location between 8 am and 9 pm and Manager A access from 4 am to 11 pm and so on. Each access point (or door) is also 100% customizable so you can limit who can access storage areas, for instance. All of this can be done at any time on the DGAPass web portal and mobile app.

Infrared (IR) security cameras can capture black-and-white images even when there is little visible light. This technology is crucial in enhancing visibility and capturing images in low-light or nighttime conditions. IR security cameras are equipped with infrared LEDs that emit infrared illumination. This illumination can then convert the reflected IR light to a grayscale image visible to the human eye, which can then be displayed or recorded for surveillance purposes. By leveraging IR technology, security cameras can effectively monitor areas with little or no available light, such as nighttime scenes or dimly lit alleys and rooms. This enables round-the-clock surveillance and enhances the overall security of a location by providing visibility in challenging lighting conditions.

Dome cameras are a popular type of security camera characterized by their darkened plastic dome-shaped housing. The dome housing serves both aesthetic and functional purposes. It provides a discreet appearance and makes it difficult for individuals to determine the direction the camera is pointing. The dome housing also protects against vandalism and tampering. Dome cameras are commonly used in indoor and outdoor environments to monitor a wide range of areas, including retail stores, office buildings, public spaces, and more.

Digital zoom is a feature in security cameras that allows for the selective enlargement of a digital image or video without physically moving the camera lens. Unlike manual zooming, which uses the lens to magnify, digital zoom relies on software processing to enlarge the pixels in the image. For this reason, digital zoom can be easier to use since it doesn't require a technician to come and adjust the lens and can be completed at the tap of a button. However, it's important to note that digital zoom may result in losing image quality and detail. It can be useful for obtaining a closer view of an object or area of interest, but for clear imaging, manual zoom is generally preferred.

In access control, fail-safe is a locking method that defaults to the unlocked or open position when power is removed or interrupted. Access systems are universally required by code to revert the locking methods to the fail-safe position upon a fire alarm activation to ensure a safe, fast exit for those inside the premises. This is often done with an electromagnetic lock (mag lock). This locking method consists of a powerful electromagnet and an armature (a metal plate). It is typically used in building entry doors or glass doors where the electromagnet is installed on or in the door frame and the armature is attached to the door. When electrified, the electromagnet keeps the door in a locked position. When a mag lock’s electromagnet loses power, the door will remain unlocked. Overall, fail-safe locking systems are crucial in ensuring safety and reliability, and they are essential for your fire safety compliant access control system.
