What is a Security Camera?

A security camera captures video of areas you want to monitor for deterrence, awareness, and evidence. While the term includes older analog CCTV, this guide focuses on modern IP (network) cameras used in SureVision systems for superior image quality, analytics, and reliability.

Why IP (SureVision) vs. Analog

  • 4K clarity and higher bitrates for faces/plates
  • PoE: power + video on one Cat5e run
  • Edge analytics (smart motion, line crossing, intrusion)
  • Seamless remote access — no monthly fees

Complete Ecosystem

Pair SureVision IP Cameras with a matching SureVision NVR for a plug-and-play system you can scale from 2 to 64 channels.

Core Components of a Security Camera System

Cameras

Mix wide-angle, motorized varifocal (optical zoom), PTZ for active monitoring, and LPR for entrances. All SureVision IP models are built for 24/7 duty.

NVR (Network Video Recorder)

Choose 2–64 channels. Records, manages users, sends alerts, and streams video to apps. Start smaller and expand as coverage grows.

PoE Cabling

Each camera uses one Ethernet run. Stock up on Cat5e PoE cables per camera based on distance.

Storage

Use surveillance-grade HDDs sized to your retention goals. Many pro installs use multi-TB drives; tune bitrates and motion schedules to extend days.

Camera Types & Use Cases

Bullet

Highly visible deterrent; great for driveways, gates, and perimeter lines.

Dome / Turret

Discreet aesthetics with vandal-resistant options; ideal for entrances and interiors.

Motorized Varifocal

Optical zoom to dial in details at distance without sacrificing image quality.

PTZ

Pan-Tilt-Zoom for active monitoring of large lots, yards, or corridors.

LPR (License Plate)

Optimized shutters and angles for capturing plates at entrances and choke points.

Specialty

Fisheye, covert, and other niche models for unique coverage needs.

Resolution, Frame Rate & Night Performance

Resolution

4K/8MP provides the most detail; 5MP and 1080p are solid for general coverage. Mix by scene importance.

Frame Rate & Bitrate

15–20 fps is often ideal for security; higher fps increases storage. Balance clarity and retention via NVR settings.

Night / Low Light

Look for strong IR, smart DNR, and color-night capabilities. Reduce glare by avoiding direct aim at lights or reflective surfaces.

Network & PoE Cabling Best Practices

  • Use quality Cat5e or better; respect max runs and avoid tight bends.
  • Budget PoE power for all cameras; consider PoE switches for larger layouts.
  • Segment CCTV with VLAN/QoS in complex networks.
Tip: For 16+ cameras, pair your NVR with a PoE switch. Your system still caps at the chosen NVR channel count, but switching simplifies cabling.

Installation & Placement

Coverage Plan

Start with entrances, cash/asset zones, parking, and blind spots. Overlap fields of view and vary angles for maximum context.

Heights & Angles

Typical mounts at 9–12 ft outdoors and 8–10 ft indoors. Avoid backlighting, consider sun paths, and shield from glare.

Weather & Vandal

Use weather-rated housings outdoors and consider vandal-resistant domes in public-facing areas.

Remote Access, Security & Apps

SureVision systems include free apps for live view, playback, and alerts. For advanced networks, use secure methods (strong passwords, current firmware, role-based users). Our team can help with best practices.

Storage & Retention

Storage needs depend on number of cameras, resolution, frame rate, scene activity, and whether you record motion-only or continuous.

Quick Sizing Pointers

  • Motion-only recording can significantly extend retention vs continuous.
  • Multi-terabyte drives are common for 8–16+ camera installs.
  • Use export for incident archiving; consider RAID for large, critical sites.

Troubleshooting & Maintenance

  • Camera offline? Check PoE power, cable seating, and NVR channel settings.
  • IR glare? Re-angle camera, clean dome/bubble, reduce reflective surfaces.
  • Noisy image? Adjust exposure, DNR, and verify adequate lighting.
  • Keep firmware current; review logs and user access periodically.

Frequently Asked Questions

Are SureVision systems truly plug-and-play?

Yes. PoE provides power and data on one cable per camera. The NVR auto-discovers compatible cameras for fast setup.

How many cameras can I add?

From 2 to 64, depending on your NVR. Choose the channel count you need today with room to grow.

Is there a monthly fee for the app?

No. Remote access is included — you own and control your footage on the NVR.

Can I mix camera types?

Absolutely. Combine domes, bullets, varifocal, PTZ, and LPR to match each scene.

What support is included?

3-Year Warranty, 30-Day Money-Back, and Lifetime U.S. Support.
