A telephoto lens is a type of camera lens with a long focal length, allowing for magnification and capturing distant subjects in detail. It has a narrow field of view, which results in a close-up view of the subject, making it ideal for surveillance applications where long-range monitoring is required. Telephoto lenses are commonly used in security cameras to monitor focused areas such as hallways or alleys.

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.
