Why Cameras and Smart Devices Belong on Their Own Network
The average home now has dozens of connected devices: cameras, TVs, thermostats, speakers, appliances and plugs. Many get infrequent security updates. Putting them on the same network as your laptop and phone is an unnecessary risk.
What segmentation means
Segmentation divides one physical network into separate logical networks, usually called VLANs, each with its own rules. Devices on one segment can't freely reach devices on another unless the firewall allows it.
A typical layout
- Personal: computers, phones and tablets for the household or staff.
- Smart devices: TVs, speakers, thermostats, appliances and hubs.
- Cameras and access control: video recorders, cameras, door readers and intercoms.
- Guests: internet access only, isolated from everything else.
- Business or work: separated from family devices in a home office or small business.
What it protects against
If a cheap smart plug or an outdated camera is compromised, segmentation keeps it from reaching your computers, files and accounts. Cameras can be prevented from sending video anywhere they shouldn't, and guests never see your devices at all.
Does it make things harder to use?
Done properly, no. Casting to a TV, printing and controlling smart devices from your phone all keep working through specific firewall rules that allow exactly what's needed. The day-to-day experience is the same, with far less exposure behind it.
How we set it up
Segmentation is part of every network we install: the gateway, switches and Wi-Fi are configured together, each network gets the access it needs, and you get documentation showing what lives where.
