The use case settles the decision
Cat6 is the right fit for a great many office, home, and camera runs when it's installed correctly. Cat6A earns its cost when you're targeting higher speeds over longer distances, or working in an environment that needs a better margin against interference.
Quality isn't printed on the jacket
The cable route, the bend radius, separation from power lines, the quality of the connectors, and how the ends are terminated all shape the result. The right move is to test each point and document it — not to stop at "the link comes up".
What a proper run looks like
- Full-copper cable, not copper-clad aluminium
- Separation from sources of interference
- Labeling at both ends
- Testing, with a report to prove it
Think about the life of the building
The cable inside the walls is the hardest element to change later. If the project is new and its needs are growing, investing in better infrastructure can be the sensible call — even if you don't use its full capacity today.
Frequently asked questions
Is Cat6 enough for 8MP cameras?
Usually yes, as long as you respect the distance, the installation quality, and the right equipment. A camera's video bitrate is far below gigabit capacity.
Is Cat6A always better?
Not always. It's thicker and more expensive, and it only pays off with matching components and proper installation.
Practical takeaways
- Match the cable to the distance, speed, and environment — not to the higher number
- Cat6, installed well, covers most office, home, and camera runs
- Reach for Cat6A on longer, faster, or interference-heavy runs
- Insist on full-copper cable, clean routing, labeling, and a test report
- For new builds with room to grow, better in-wall infrastructure is cheap insurance
