CCTV Camera Expert Guide

This guide breaks down how to choose the right CCTV cameras for a reliable HD over coax system— including camera styles, resolution, night vision, audio microphones, and DVR recording basics.

What makes CCTV “HD Over Coax”?
HD CCTV uses coax cabling to deliver a stable, wired video signal to a DVR. It’s a proven approach for reliability, clean playback, and straightforward expansion when your DVR has open channels.
Best use-cases
Homes, small businesses, and facilities that want wired stability, DVR recording, and strong night performance without depending on Wi-Fi.

CCTV Camera Styles: Bullet vs Dome vs Turret
  • Bullet cameras are great for perimeter lines and long sightlines (driveways, fences, side yards).
  • Dome cameras are compact and clean-looking, often used at entries and under eaves.
  • Turret (eyeball) domes are easy to aim and popular for both indoor and outdoor installs.
  • Vandal-resistant domes are a smart upgrade for reachable mounting locations.
1080p vs 4K CCTV: What to pick?
1080p (2MP)
Great value for general coverage. Ideal when you want multiple cameras and strong overall visibility.
4K (8MP)
Best for capturing detail (faces, activity) and tighter digital zoom. Strong choice for drive lanes and entrances.

Tip: camera placement matters as much as resolution. A properly-aimed 1080p camera can outperform a poorly-placed 4K camera.

Night Vision & Low Light Performance
Look for strong infrared night vision ratings and consider lighting conditions (street lights, porch lights, motion lights). Avoid aiming IR cameras directly at reflective surfaces or glass, which can cause glare at night.
Built-in Microphone Audio: When it helps
Audio is useful at entries, service counters, and delivery areas. For best results, mount microphones away from heavy wind noise and mechanical hum. (Always follow local laws regarding audio recording.)
Camera Placement: A simple pro framework
  1. Cover every entry (front, back, side doors, gates).
  2. Cover approach paths (driveway, walkway, parking lanes).
  3. Cover high-value areas (register, inventory, docks, tools).
  4. Eliminate blind spots at corners and transitions.

CCTV Camera FAQs
Which CCTV camera style is best outdoors?
Bullet and turret styles are popular outdoors due to aiming flexibility and strong perimeter coverage. Domes are great under eaves and entries.
Is 4K always better than 1080p?
Not always. 4K captures more detail, but placement, lighting, and aiming matter just as much. Many installs mix 4K for key views and 1080p for general coverage.
Do CCTV cameras need internet?
No. Cameras record to a local DVR. Internet is optional if you want remote viewing.
