Why VLANs help
They let you separate traffic logically even when devices share physical switching infrastructure. That is useful when CCTV traffic should stay apart from office devices or guest Wi-Fi.
When VLANs make sense
- Higher camera counts
- Guest Wi-Fi on the same switching environment
- Cleaner support boundaries for office and surveillance systems
- Sites with firewall rules or remote access policy needs
When they may be overkill
On very small sites with a handful of devices, a simple documented flat network can be easier to support than a complicated VLAN design no one maintains properly.
The goal is not “more VLANs.” The goal is a network that stays understandable after the install team leaves.
