The short version
For new business installs, IP cameras are usually the stronger default. They fit modern networks, support PoE, integrate with access control and are easier to manage across sites. Analogue can still be part of a staged migration if the existing system is working and budget is tight.
| Option | Best fit | Watch-out |
|---|---|---|
| IP cameras | New installs, multi-site, remote access, modern security platforms | Needs proper network, PoE and storage design |
| Analogue CCTV | Existing systems and staged upgrades | Less flexible and harder to integrate with modern network platforms |
Design the network first
Security cameras are network devices. They need switching capacity, PoE budgets, VLANs, firewall rules, storage sizing and user permissions. Treating them as a separate trade often creates support problems later.
Plan retention and access
Decide how long footage needs to be kept, who can view it, and whether remote access is required before choosing camera models or recorder size.
