3. The Three Main ALPR Connectivity Options
When planning your automatic license plate recognition system, you have three main network connectivity choices. Each has its own strengths and weaknesses.
We will look at each network connectivity option in detail to help you make the right choice.
Wired Connections (Ethernet/Fiber)
Physical cables that connect your ALPR cameras directly to your network. This includes traditional Ethernet cables and high-speed fiber optic connections.
Wireless Connections (Wi-Fi)
Radio signals that connect your license plate recognition cameras to wireless access points, which then connect to your main network.
Cellular Connections (4G/5G)
Mobile network connections that use cell towers to transmit data from your license plate capture cameras to your central system.
4. Wired Network Connectivity: The Reliable Workhorse
a) How Wired Network Connectivity Works for ALPR Systems
Wired connections use physical cables to carry data from your license plate reader cameras to your central system. This can be standard Ethernet cables (Cat5e, Cat6) for shorter distances or fiber optic cables for longer distances and higher speeds.
The data travels directly through the cable without interference from weather, other electronic devices, or network congestion. This makes wired network connectivity the most reliable option for critical ALPR applications.
You have an option of renting wired connectivity from a public ISP where they will dedicate a part of their wired bandwidth for you, but the limitation is this will only be available for the specific routes the ISP has laid cabling for.
The other option is to run cables yourself for the specific network you are designing.
b) Best Use Cases for Wired Network Connectivity
Permanent Installations: When your automatic license plate reader cameras will stay in the same location for years, wired network connectivity makes sense. Examples include:
High-Data Applications: When you need to send large amounts of data quickly:
Mission-Critical Operations: When system downtime isn't acceptable:
