How to Choose the Best Battery Backup for Your Home Security System
Choosing the right battery backup starts with knowing your system’s wattage. Most routers draw 10–20W, Wi‑Fi cameras draw 3–7W each, and PoE cameras draw 5–15W each depending on IR usage. NVRs typically draw 10–40W. Add everything together, then choose a UPS or power station that can handle at least 2× your typical load.
| Security System Type | Typical Draw | Recommended Backup Size |
|---|---|---|
| Router + modem | 10–25W | 400–600VA UPS |
| Router + Wi‑Fi cameras | 20–60W | 850–1000VA UPS |
| NVR + PoE switch + cameras | 40–120W | 1000–1500VA UPS |
| Whole‑home security cluster | 40–80W | 500–1500Wh power station |
