Video camera: Some entry intercoms incorporate a built-in camera that captures and transmits an image of the visitor to the substation, allowing occupants to better assess a visitor and verify their identity before granting access.This allows occupants to communicate with visitors before granting access. When visitors press the buzzer at the master station, it alerts occupants in their office or apartment that someone is at the door and activates the microphone and speakers. Buzzer: Door entry intercom systems typically include a buzzer.It connects directly to the master station for communication, allowing occupants to hear and respond to visitors. This can be a microphone, computer screen, surveillance monitor, or smartphone that allows occupants to communicate with and grant access to visitors. Substation: The substation is the device located in individual rooms or apartments.The master station may also include a release mechanism, such as an electronic door opener, to allow access to the facility when authorized. It connects to a substation either wirelessly or through a wired connection. It can take various forms, such as an audio speaker with a microphone, a video phone, or even a simple keypad. Master station: This is the device located at the entry point and is used to communicate with visitors.How does a door entry intercom system work?Īn intercom door entry system is used to control access at one or multiple entry points and involves a number of components: Incorporating security intercoms with commercial surveillance cameras gives organizations an extra layer of protection. Intercom security systems can also be integrated with surveillance cameras so that security personnel can monitor activities taking place outside of their premises from anywhere in the world. This makes commercial and office intercom systems invaluable for businesses that need to keep out intruders, along with providing secure access for employees at any time of day or night. Intercom systems also provide access control functionality, allowing authorized personnel to open doors remotely instead of having to physically go and open them every time there is a visitor. They can be used as a backup method of communication when phone networks are down due to a natural disaster or technical issue, making them essential for organizations with important security protocols that cannot afford interruptions. Modern intercom systems play an essential role in security. Intercom systems are commonly found in businesses, schools and homes. More advanced systems feature video and audio capabilities, allowing users to see and hear each other. The most basic type of intercom system is an audio-only device that can be used for simple conversations, such as announcing visitors at the front door. This unit is vertically oriented, so while it doesn't have a large footprint, it will resemble a computer tower.An intercom system is a device that allows communication between one or more people in different locations. We feel five outlets should cover most setups adequately. While this APC model has ten outlets, only five are connected to the battery (the other five have surge protection, though). It's a bit expensive but a great battery backup for medium applications. This device can also deliver over 800 watts of power, so you can safely charge any device at the speed you typically experience by plugging the same charger directly into a wall outlet. While simulating a power outage by flipping a circuit breaker in the house, the UPS immediately kept our test computer running with plenty of time to save my work and shut it down. The APC Back-UPS Pro 1500 is a utilitarian device, but it has a little LCD screen showing vital information like input voltage, battery status, and the current load, which is a nice touch.
