Types of Security Camera Systems (IP, CCTV, PoE, Wireless)

 

When people search for a security camera system, they may mean an IP NVR camera system, a PoE camera system, a classic CCTV DVR system, or a wireless camera system. This page is a quick guide to help you choose the right technology for business, home, or government installs—then jump directly into the correct category.

If you want the most reliable, evidence-quality video, professional systems use wired infrastructure and local recording (NVR or DVR) so you’re not dependent on cloud subscriptions. Most customers choose IP/PoE NVR camera systems for best performance, or HD-over-coax (CCTV) DVR systems when upgrading an older site with existing coax.

1) IP / PoE Camera Systems
 
Network-based cameras powered by PoE. Best for new installs, highest quality, and easiest expansion. Common names: PoE camera system, IP NVR system, NVR camera system.
Best for: business, warehouses, schools, government, and pro-grade home installs.
2) HD-over-Coax (CCTV) Systems
 
Ideal when coax wiring already exists. Upgrade older CCTV to HD video without rewiring the building. Common names: HD CCTV system, DVR camera system, HD-over-coax.
Best for: fast retrofits, budget-friendly upgrades, reusing coax infrastructure.
3) Wireless Camera Systems
 
Useful for select scenarios where wiring is difficult. Wireless can be convenient, but reliability depends on Wi-Fi coverage, interference, and placement. For mission-critical sites, wired IP or coax is typically the safer choice.
Best for: short runs, temporary coverage, and specific low-risk areas.

Security Camera System FAQ (IP, CCTV, PoE, Wireless)

What is an “IP NVR camera system” or “PoE camera system”?
It’s a wired IP camera system where each camera connects by Ethernet and is powered by PoE. Video records to an NVR for reliable 24/7 recording and scalable storage.
What is an HD-over-coax CCTV DVR system?
It’s a wired CCTV system that sends HD video over coax cabling and records to a DVR. It’s ideal when coax wiring already exists and you want a faster upgrade.
Are wired systems better than wireless for business or government?
In most cases, yes. Wired systems (IP/PoE or coax) are more consistent for evidence-quality video and retention because they don’t rely on Wi-Fi signal conditions.
Do your systems require monthly fees?
No. Professional systems record locally to an NVR or DVR—so you avoid cloud subscriptions.
Need help choosing the right system type?
Tell us your site type (business, home, or government), key areas to cover, and how many days of recording you want. We’ll recommend the right technology (IP/PoE, HD CCTV, or wireless where appropriate).
