The question comes up on almost every security camera project we bid: can't we just use wireless cameras? The answer is almost always no — and here's why.
The Case for Wired
A wired camera runs on its own cable. Cat 6 from the camera back to the recorder or switch. It doesn't use your Wi-Fi. It doesn't compete with your other devices. It doesn't go offline when your wireless access point reboots or gets congested.
In a commercial facility — a warehouse, a distribution center, a manufacturing floor — your wireless network is already under load. Barcode scanners, handheld devices, laptops, VoIP phones, and guest access are all competing for bandwidth. Adding 20 or 40 cameras to that same network creates problems. Congestion, dropped frames, offline cameras during shift changes when everyone logs on at once.
A wired system avoids all of that. The cameras run on their own infrastructure, completely independent of your production network.
When Wireless Makes Sense
Short answer: almost never for a permanent commercial install. The only cases where wireless cameras are genuinely acceptable are temporary installations (job sites, events) or locations where running cable is physically impossible — a detached building with no conduit path, a remote gate with no power run yet.
Even in those cases, we prefer to run the cable if we can. A temporary wireless camera at a remote gate is fine for 90 days. After that, run the cable.
What to Ask Before You Buy
Before anyone installs cameras at your facility, ask: how are these cameras connected? If the answer is Wi-Fi or cellular, ask why. If the answer is "it's easier," that's not good enough. Wireless cameras are easier to install and harder to keep running. Wired cameras take more work up front and run reliably for years.
