Doorking Intercom System Comparison

A video intercom monitor is often treated as just a screen on the wall. In reality, it is one of the key parts of the system: it is the device through which the user receives the call, sees the visitor, speaks with them and manages access. What a Video Intercom Monitor Is A video intercom […]

When the word “SIP” appears in the specifications of an intercom or entry panel, it often sounds like something purely technical. In practice, the meaning is much more practical. SIP is a protocol used to establish communication between devices on a network. Put simply, it helps one system “call” another, establish a connection, and begin […]

When people first come across the term “IP video intercom,” it often sounds more technical than it really is. In practice, the basic idea is fairly simple. An IP video intercom is an intercom system that works over a network. In other words, communication between the entry panel, the indoor monitor, and other devices is […]

What PoE Means in Simple Terms PoE stands for Power over Ethernet. Put simply, it means that the same Ethernet cable can carry both data and power. That means that, for some devices, you do not need a separate network connection and a separate power feed. If the equipment supports PoE, one cable may be […]

That is a convenient story if someone only wants to sell IP […]

Start Not with the Design, but with the Use Scenario The most common mistake is choosing an entry panel without a clear task in mind. A panel for a private house, a block of flats, an office, or a commercial site is not the same thing. First, answer the basic questions: How many users will […]

What the Difference Actually Is A flush-mounted panel is recessed into the wall or into a prepared niche, so only the front face remains visible from the outside.
