Security camera / NVR backup (PoE + modem)

Keep recording and alerting when the grid drops: size a station for NVR / PoE switch + cameras + modem / router. Pure internet brick math: Wi‑Fi / modem backup. Desk day stack: WFH outage.

Security load stack (planning watts)

  • Modem / ONT + router. ~10–30 W — required for cloud alerts / remote view.
  • NVR / DVR. Often ~10–40 W depending on drives and channels.
  • PoE switch + cameras. Budget ~4–12 W per camera class (IR / PTZ higher); eight cameras can rival a laptop.
  • Wi‑Fi battery cams may already have onboard cells — still charge hubs / base stations if used.
  • UPS vs station. A tiny UPS bridges flickers; Wh for overnight comes from a portable station (same story as home office UPS).

Typical small kit (modem + NVR + 4 PoE cams): about ~40–80 W continuous. Specs from manufacturer pages (checked Oct 2026). Figures are estimates.

Overnight Wh estimates

Hours ≈ (rated Wh × 0.85) ÷ average watts.

Modem + NVR only (~35 W)

~7–50 h

286 Wh ≈ 7 h · 1,024 Wh ≈ 25 h (estimates)

+ 4 PoE cams (~60 W)

~4–29 h

1 kWh ≈ overnight+ for many homes (estimates)

8-cam / PTZ heavy (~100 W+)

Size up

Aim 2 kWh / expandables for multi-night recording + upload

Comparison: camera / NVR blackout stations

Filter by kit size. Prefer UPS-class switchover so NVRs don’t corrupt on flicker.

Model Wh · UPS Est. @ ~40–80 W Security note Approx. USD
EcoFlow RIVER 3 Plus Modem + NVR 286 Wh · UPS <10 ms ~3–6 h @ 40–80 W (est.) Short outages / few cams; expand before all-night PoE. ~$180–300
Anker SOLIX C300 288 Wh · 300 W ~3–6 h class (est.) Fine for modem + light NVR; watch PoE switch draw. ~$200–280
Jackery Explorer 1000 v2 Quiet closet 1,070 Wh · UPS <20 ms ~11–22 h (est.) Overnight 4-cam class for many homes. ~$499–589
BLUETTI Elite 100 V2 1,024 Wh · UPS ≤10 ms ~11–21 h class (est.) Fast transfer helps NVRs / PoE injectors on flicker. ~$380–500
Anker SOLIX C1000 Expand 1,056 Wh · UPS <20 ms ~11–22 h · ~2× expanded Add pack when storms + cameras + WFH share one box. ~$400–600
EcoFlow DELTA 3 Plus 1,024 Wh expandable · UPS <10 ms Overnight solo; multi-day with extras Closet / rack sidekick for larger PoE counts. ~$600–900+
BLUETTI AC200L 2,048 Wh · 2,400 W ~21–43 h class (est.) Multi-night recording + upload buffer. ~$800–1,100
