Digital buildings, smart buildings, intelligent buildings, connected buildings – no matter what you call them, the sentiment is the same: A building with devices and systems that are designed to collect and share data to run as efficiently as possible without human intervention.
IP-based systems – also known as networked systems – are what make this idea possible. These systems use Internet Protocol (IP) to communicate with each other through IP addresses and data packets. All types of building devices can be IP-based:
To function, an IP-based system needs access to power and data. When deployed in digital buildings, they offer many benefits:
Only need 15 surveillance cameras today? Then that’s all you need to install. If you decide you need more devices, the system can quickly and easily be expanded. If you decide that you need fewer devices, they’re easy to uninstall. The system doesn’t require you to install a certain number at a time.
Because they’re connected to the network, IP-based systems can send you alerts or notifications via texts, calls, emails – whatever you prefer – about potential problems, changes, etc. Want to know if one of your digital signage screens goes down? An IP-based digital signage system can tell you. Want to know if someone has breached your physical access control system? An IP-based access control system can tell you that, too.
Communication with Other Systems
IP-based systems are easier to connect and integrate to work and communicate with each other. An example: connecting fire alarm systems and digital signage. If the fire alarm system senses a potential event, the digital signage system – which can communicate with the fire alarm system – can display instructions and evacuation procedures.
In legacy systems, one single point of failure could cause entire portions of the system – or the entire system itself – to stop working. Because IP-based devices are independent of each other, and have their own IP addresses, a single point of failure only impacts that one device. If one surveillance camera goes down, the rest of the cameras remain operational.
With IP-based systems connected to the enterprise network, they can be monitored and managed via a standard web browser. Wherever you can connect to the Internet – at home, at work, on vacation or at the store – you can keep an eye on building system performance.
If an IP-based device goes down, it’s easy to perform troubleshooting or maintenance on that device without needing to take the entire system offline or waiting until off hours. In most cases, there’s no need for a middleware device; connections are created directly between the field device and the enterprise network.
How Does PoE Support IP-Based Systems?
Power over Ethernet (PoE) cabling systems can help you make the most of IP-based systems and devices. PoE allows you to use one cable to transport data and power instead of two separate wires/cables: one for electricity and one for data transmission. Carrying both through one cable offers many benefits for digital buildings that utilize IP-based systems:
Because of its larger-gauge diameter, ability to maximize power transmission and insertion loss margin that can handle heat generated from tightly packed cables, Category 6A cabling is recommended for PoE applications.
Belden’s 10GXS small-diameter cable delivers more than 100W up to 60C and 100 m channels. It supports 1, 2.5, 5 and 10GBASE-T without any deployment restrictions. It provides uniform heat dissipation, while its small outside diameter reduces cable space and weight by 25%.
