#securitycamerabackup

Power outage = Wi-Fi down, cameras off, alarm panel offline, and your small office network suddenly disappears. 😬 That’s why an AGM battery backup is still one of the most reliable options for security camera backup, alarm panel battery backup, and a router UPS battery setup across Canada.

In this quick guide, we compare three popular AGM choices: Altilium EA12-100, EA12-220, and NP400-6 — and help you pick the right battery based on runtime, footprint, and real-world use.

Why choose an AGM battery for security + UPS?

A reliable AGM lead acid battery works great for standby power because it’s:

✅ Sealed + maintenance-free ✅ Designed for standby/float charging (UPS-friendly) ✅ Excellent for routers, modems/ONT, alarm panels, CCTV cameras, NVRs, access control ✅ Proven performance for Canadian homes + small businesses

Fact: AGM batteries are VRLA (valve regulated lead acid) batteries — built for dependable standby power when sized and charged correctly.

Quick comparison (simple)

🔋 EA12-100 (12V 100Ah)

Best for: router UPS battery backup, small alarm panels, light CCTV backup Why it’s popular: best balance of size + price + capacity Trade-off: may be limited for longer runtime with many cameras + NVR

🔋 EA12-220 (12V 220Ah)

Best for: longer backup time, multiple devices, CCTV + NVR overnight backup Why it’s great: more usable energy, more margin, less stress on the battery Trade-off: heavier + larger + higher cost

🔋 NP400-6 (6V)

Best for: compact telecom/rack banks (series-parallel builds) Why people use it: flexible bank building where space is tight Trade-off: needs proper wiring (series/parallel) to hit 12V/24V and required capacity

Ah vs Wh (plain English)

Battery runtime is easier in Wh (watt-hours):

Wh = Volts × Ah Example: 12V × 100Ah = 1200Wh

Real-world runtime is less because of:

UPS/inverter losses

voltage sag at higher loads

safe depth of discharge (many users plan around 50% DoD for longer life)

How runtime changes with load

Low loads (10–30W): many hours (often overnight or longer)

Moderate loads (100–300W): usually a few hours

Higher loads reduce usable capacity faster

Tip: list every device and use average watts: modem/ONT, router, NVR, switch, access control, etc.

Real-world examples (Canada)

📌 Home Wi-Fi backup (router + ONT) If your draw is around 10–15W and you want 8 hours, you often need less capacity than expected. Many choose EA12-100 just for big safety margin.

📌 CCTV + NVR overnight backup 4 cameras + NVR typically sits around 25–40W. For ~12 hours, EA12-100 often fits well. Want more margin? EA12-220 is smoother.

📌 Small office network closet Routers + switch + VoIP + access control commonly hits 65–85W. For 6 hours, EA12-220 (or 2× EA12-100 in parallel) is a common approach.

Which one should you choose?

Choose EA12-100 if you want the best all-rounder for: ✔ router UPS battery backup ✔ alarm panel battery backup ✔ small CCTV setups

Choose EA12-220 if you need: ✔ longer runtime (CCTV + NVR, multiple devices) ✔ more resilience during long outages ✔ better battery life (lower discharge per outage)

Choose NP400-6 if you’re building: ✔ compact rack/bank systems ✔ modular series/parallel battery banks
