Choosing the Right Security Camera System
Choosing the right security camera system starts with proper system design. The right camera coverage, resolution, and recorder capacity helps protect entrances, perimeters, and critical areas—without blind spots or unnecessary hardware.
Our professional security camera systems are built to scale. Start with the cameras you need today and expand later without replacing your NVR, cabling, or core components.
Not all systems perform the same. Learn why professional security camera systems outperform consumer cameras for reliability, clarity, and long-term value.
Quick Guide: IP / PoE / NVR Terms (For Smarter System Shopping)
Glossary Links
These terms show up across security cameras, surveillance cameras, and PoE security camera systems. Use this quick guide to choose the right setup with no monthly fees.
IP Camera
A digital
security camera that sends video over a network (Ethernet). Most modern professional systems are
IP cameras.

PoE (Power over Ethernet)
Runs
power + video on one Cat5e/Cat6 cable—fewer parts, cleaner installs, and higher reliability than Wi-Fi.

NVR (Network Video Recorder)
Records your
surveillance camera video locally (no cloud required). Enables 24/7 recording, playback, and storage.

Security Camera Systems — Frequently Asked Questions
Do security camera systems have monthly fees?
No. Our professional systems record locally to an NVR, so you avoid subscription-based cloud fees.
Can I expand my security camera system later?
Yes. Most installations can expand by adding cameras, storage, or switches as needs change—without replacing the entire system.
What is the difference between PoE IP and HD Over Coax?
PoE IP systems use Ethernet (Cat5e/Cat6) to carry power + video to an NVR for higher resolution and modern features. HD Over Coax uses coax cable with DVRs and is common in older analog installs.
Which system is best for outdoor coverage?
Outdoor areas like driveways, parking, and perimeters do best with outdoor-rated cameras and a wired PoE design for stable 24/7 recording. See outdoor security camera systems .
Looking for HD Over Coax or Older CCTV Systems?
If you’re upgrading but still need support for HD CCTV Over Coax equipment, we’ve got you covered. While PoE IP security camera systems are the modern professional standard for new installs, many existing setups still use coax + DVR technology — and we support them too.
