Blue Iris UPS buying guide
A Blue Iris UPS has to protect the surveillance path, not only the computer tower. If the recorder stays on but the PoE switch, router or ONT shuts off, camera coverage can disappear. Size protected watts from measured equipment load, then use the exact UPS manufacturer runtime curve or battery data for the runtime decision.
Quick answer
Start with watts, then check runtime on the exact UPS
VA is not a universal runtime measure. Add the recorder, PoE camera load, switch electronics and network edge watts. Choose a UPS whose real watt rating leaves margin, then verify minutes at that load with the vendor.

Buying decision
Protect enough of the chain to preserve useful recording
The best boundary depends on the deployment. At minimum, identify which cameras, switches and network devices must remain operational during a short outage and include those loads in the power plan.

Use measured camera bitrate, equipment watts and the retention policy you actually need. The tools use direct unit conversion and planning headroom; they do not invent camera throughput, PoE draw, disk speed or UPS runtime. Verify exact product specifications before purchase.
Compatibility checklist
Four checks before buying surveillance infrastructure
Measure streams instead of guessing
Use actual camera Mbps for storage and network planning. Resolution and codec labels alone do not determine bytes written or link utilization.
Count PoE ports and watts separately
A switch needs enough powered ports and enough total power budget. Night IR, heaters and PTZ movement can change the worst-case load.
Do not convert VA directly into runtime
UPS runtime depends on the exact battery system and connected watts. Use manufacturer runtime data after the protected load is calculated.
Backup must survive a different failure
A second copy is useful when it has an independent retention and recovery path. RAID or another folder on the same recorder is not the same protection goal.
The protected load should include the camera power path
A Blue Iris recorder can remain perfectly powered while every PoE camera goes dark because the switch lost AC input. Include the switch base load and the watts delivered to cameras if continuity during an outage matters. If cameras are split across several switches, decide which groups are critical and which UPS protects each location.
Measure recorder watts instead of estimating from the power supply label
A 500W or 750W PC power supply does not mean the recorder continuously consumes that amount. Use a wall power meter or reliable UPS telemetry to observe idle and busy recording load. Include a higher representative value for AI processing, exports and disk activity so the UPS output rating has margin during real work.
PoE camera watts belong in the UPS calculation
The switch draws its own operating power and also supplies camera power. If a camera is rated for a higher maximum draw when IR, heaters or motors are active, use that maximum or a measured worst case. Nighttime can therefore be a more meaningful power test than the daytime setup session.
VA and watts describe different limits
UPS listings commonly advertise VA prominently, but the connected equipment ultimately consumes real watts. Power factor means two UPS models with the same VA can have different watt ratings. Cloudzat records both only when the listing provides evidence. The planner produces a required watt target and tells you to check the exact model instead of converting VA to runtime generically.
Runtime depends on load and the exact battery system
Battery runtime is not proportional to VA alone. CyberPower's official runtime calculator asks for a specific UPS model and load, and UPS vendors publish model-specific curves or estimates. This page therefore calculates the battery energy that would theoretically support a desired duration when usable watt-hours are known, but it does not claim a runtime for an Amazon listing without manufacturer evidence.
Short graceful-shutdown runtime can be more useful than chasing hours
For many home and small-office recorders, the UPS goal is to ride through brief interruptions and give Windows time to shut down cleanly during a longer outage. Hours of camera operation require substantially more battery energy, especially when a large PoE switch is included. Define the continuity objective before buying a larger UPS simply because its VA number is higher.
USB or network shutdown integration should be verified
A UPS can protect power without automatically shutting down the recorder. If graceful shutdown is required, verify the communication method, Windows software support and behavior of the exact UPS model. Test the shutdown workflow under controlled conditions so an outage does not reveal that the cable, service or permissions were never configured.
Separate UPS units can improve physical topology
A recorder and core switch in the same rack may share one UPS, while remote PoE switches need local battery backup. Several smaller UPS units can protect distributed failure domains more effectively than one central device that cannot power remote equipment. The tradeoff is more batteries to monitor and replace.
Battery age changes available runtime
UPS batteries are consumable components. Runtime declines with age, temperature and cycle history, so the day-one vendor estimate is not permanent. Schedule self-tests where appropriate, track battery replacement guidance and remeasure protected load after adding cameras, drives or network hardware.
Surge-only products are not UPS systems
Marketplace results can mix battery backups with surge protectors, replacement battery cartridges, PDUs, portable power stations and inverters. A cheap surge strip may protect against some electrical events but it cannot keep Blue Iris recording during an outage.
High PoE loads may need a higher power class than the recorder
A compact recorder can draw less power than a switch feeding dozens of IR cameras. In that scenario the camera-power side, not the PC, drives UPS sizing. Calculate each load independently and consider whether all cameras require the same outage runtime. Critical entrances might justify longer battery support than secondary views.
Test outage behavior as part of commissioning
After the UPS is installed, simulate a controlled power loss while watching camera continuity, recorder logs, switch behavior and shutdown actions. Confirm that the protected load stays below the UPS rating and that runtime is consistent with the vendor estimate. A surveillance power plan is not complete until the equipment has demonstrated the intended failure behavior.
Questions people ask
Best UPS for Blue Iris FAQs
What size UPS do I need for Blue Iris?
Add the real watts of the recorder, PoE switch, camera PoE load and any network equipment that must remain powered. Then choose a UPS with watt headroom.
Can I calculate runtime from VA?
No. Runtime depends on the exact battery system and connected load. Use the manufacturer runtime curve or calculator for the selected UPS.
Should the PoE switch be on the same UPS?
If cameras must keep recording during an outage, their power path needs battery protection. That may be the same UPS or a separate unit.
How much UPS headroom should I leave?
Avoid sizing at the exact output limit. The calculator uses configurable headroom so transient and future loads have room.
Does a larger VA number always mean longer runtime?
No. Compare watt rating, battery configuration and manufacturer runtime at your actual load.
Should I protect the router and ONT too?
If remote access or network services must remain available, include the relevant edge devices in the protected-load plan.
Can Blue Iris shut down automatically on UPS battery?
Windows shutdown automation depends on the UPS communication interface and supported software. Verify and test the exact model.
Are portable power stations the same as UPS units?
No. Some may offer UPS-like modes, but this catalogue intentionally separates them from conventional UPS products.
How often should UPS batteries be replaced?
Follow the exact manufacturer guidance and battery health data. Heat, age and cycling affect usable runtime.
Why does the page show UPS watts and VA separately?
They are different electrical ratings. Keeping both visible prevents a VA figure from being treated as guaranteed real-power capacity or runtime.
