4K Security Camera Systems & Cameras

Not strictly. Where 4K lands depends on your display:

• 1080p monitor — live view looks the same as 1080p, but playback earns: pause and zoom into a plate or face, extra pixels are on disk
• 4K monitor (recommended) — live view shows full 4K detail in real time

A 4K monitor runs $200-$500 extra. Evidence-driven sites (parking, retail, warehouses): worth it. Otherwise, skip it.

Worth it if any of these match your site:

• License plates past 25m — 1080p reads to ~20m, 4K to 35m (Source: Axis Communications, 2023 Whitepaper)
• Facial recognition past 10m — 1080p usable to 5-8m, 4K doubles that
• Retail inventory detail at 6m+ — shelf-level shrink evidence

Sub-5m monitoring with a $1,000 budget? 1080p or 5MP gives more per dollar. 4K only earns its premium when extra pixels change the outcome.

30-40 GB event-triggered, 45-55 GB running 24/7. That's 2-3× a 1080p camera at 30fps H.265.Sizing a 16-channel 4K system:

• 4TB (4COVR default) — 7-10 days of 24/7
• 8TB — 15-20 days
• 20TB max (2× 10TB) — 38-40 days

Yes. A 4COVR 4K NVR takes 1080p, 5MP, and 4K streams on any channel and records each at the camera's native resolution.Common split on a 16-channel NVR: 4 × 4K at critical points (entry, cash register, perimeter) + 12 × 1080p at secondary spots (corridors, stockrooms). One system, pay 4K only where evidence matters.

4COVR 16 channel 4K with default 4TB HDD:

• 24/7 continuous — 7-10 days
• Event-triggered (35% motion) — 20-28 days

HDD scales: 8TB doubles retention, 20TB max (2× 10TB) gives ~5× the 4TB baseline. Most sites run 7-14 days; bump HDD or move low-priority channels to motion-triggered if you need more.
