Complete Blue Iris sizing calculator
Blue Iris Hardware Calculator: Cameras, Storage, CPU & PoE
A surveillance recorder is a pipeline: cameras create video, the network transports it, the PC processes it, storage retains it, and power keeps the system alive. This calculator combines those decisions so the final Blue Iris build does not optimize one component while leaving another as the bottleneck.
Quick answer
Enter real stream settings and let the architecture follow the workload
Use measured or realistic camera bitrate, resolution, FPS, recording fraction and retention. The tool calculates network and storage directly from those inputs, then places CPU/RAM, GPU, PoE and drive choices into directional planning tiers that must be validated on the final system.

Current hardware for this Blue Iris decision
Products come from this sprint's dedicated catalogue. Complete PCs, mini PCs, NVIDIA GPUs, surveillance HDDs, internal SSDs, PoE switches and UPS systems stay in separate classes. Laptops, barebones, external drives, enclosures, injectors, replacement batteries and obvious wrong product types are rejected.
Buying decision
Use the result as a procurement map, not a benchmark guarantee
The calculator is intentionally conservative about compute. Blue Iris performance varies with cameras, codec, substreams, AI, remote users and hardware acceleration. Exact capacity math can be derived from bitrate; exact CPU or GPU throughput must be tested.

Use the inputs to turn camera count into a workload plan. Storage math is based on the bitrate you enter; compute tiers are directional Cloudzat planning guidance, not Blue Iris benchmark guarantees. Verify the exact processor graphics, GPU codec support, drive model, PoE budget and measured camera bitrates before purchase.
Compatibility checklist
Four checks before buying Blue Iris hardware
Size from the actual camera workload
Camera count alone is not enough. Resolution, frame rate, codec, bitrate, substreams, AI analysis and remote viewing all change the compute and storage path.
Treat hardware acceleration as model-specific
Blue Iris 6 integrates Intel QSV/oneVPL and NVIDIA video acceleration, but the exact CPU or GPU must expose the required hardware features. Do not infer support from a family name alone.
Separate recording storage from the system drive
Keep Windows, the Blue Iris database and recorded video roles clear. Surveillance HDDs are designed for continuous recording, while SSDs can serve the OS/database or high-speed clip workflows.
Power and network are part of the recorder
PoE capacity, switch uplinks, UPS runtime and NIC bandwidth can stop a surveillance system even when the PC itself is fast enough. Plan the whole path from camera to disk.
The calculator begins with camera ingress
Camera count multiplied by average bitrate gives the main inbound network rate. This is exact arithmetic from the value entered, not an estimate based on resolution labels.
Keep in mind that actual bitrate can change with scene complexity and variable-bitrate settings. Use a measured busy-period average when possible and leave network margin.
Pixel rate is a comparative compute indicator
Camera count × megapixels × FPS provides an aggregate pixel-rate number. It is useful for comparing two proposed deployments even though it is not an official Blue Iris CPU benchmark.
Cloudzat uses it alongside AI, remote viewers and substream configuration to select a broad CPU planning tier. The final CPU must still be validated with Blue Iris on the intended hardware.
Recording capacity is derived from bits written over time
One megabit per second recorded continuously is about 10.8GB per day in decimal units. Multiply by total camera bitrate and retention days, then adjust for event-recording fraction and free-space reserve.
The calculator performs this math transparently. If real disk consumption differs after deployment, update the measured bitrate rather than blaming the capacity formula.
The drive recommendation follows retention capacity
Small archives may fit comfortably on one surveillance HDD. Larger archives may justify higher-capacity models or several recording volumes.
Multiple drives can also spread write workload and simplify replacement, but separate recording volumes are not automatically redundant. Decide evidence protection separately.
RAM is rounded to a practical tier
Blue Iris publishes an 8GB minimum and recommends more memory for high-megapixel cameras. Built-in AI and other Windows workloads add further pressure.
The calculator therefore rounds upward to 16GB, 32GB, 64GB or 128GB planning tiers rather than presenting false precision such as 23GB.
GPU direction starts with exact Intel graphics support
When a supported Intel iGPU is available and enabled, Blue Iris can use Intel hardware video acceleration. That makes the existing integrated graphics the first path to test in many systems.
A dedicated NVIDIA card is suggested only when the user plans one or the workload makes it worth evaluating. The output does not claim that a specific card guarantees a camera count.
PoE port count is calculated separately from PoE budget
The tool recommends a switch port class from the number of PoE cameras. The total electrical budget cannot be calculated without the maximum watts for each exact camera.
Use the output as a port-count shortlist, then sum camera power from manufacturer data sheets and compare it with the switch’s documented PoE budget.
Network choice should include playback as well as recording
Camera streams are primarily inbound, while remote viewing, exports and network storage can add other traffic. A recorder that fits within 1GbE during recording may still benefit from 2.5GbE when multiple operators review footage simultaneously.
Treat the calculated ingress as the floor and observe the actual switch and NIC counters during peak usage before upgrading to 10GbE.
UPS selection cannot come from VA alone
The calculator flags whether UPS protection is missing but does not generate a fake runtime. Actual battery time depends on recorder, switch, camera load, battery condition and the manufacturer’s discharge curve.
Measure watts for the recorder and PoE infrastructure, then use the exact UPS runtime chart. Decide whether the goal is a few minutes for graceful shutdown or continued surveillance through longer outages.
Storage redundancy and backup must be designed explicitly
A mirror can protect against one drive failure but does not protect against accidental deletion, ransomware, recorder theft or a site-wide event. Important evidence needs an independent retention and export strategy.
The calculator therefore reports recording capacity without silently doubling it for redundancy. Add redundancy and backup according to the risk policy after the primary retention requirement is known.
The PC chassis should be chosen after all expansion decisions
GPU, hard drives, NICs and cooling all consume physical resources. A compact mini PC may meet the compute requirement but fail the build because the storage or GPU plan has nowhere to go.
Read the finished calculator result from bottom to top before purchasing: retention drives, PoE, network and GPU requirements often decide the best chassis more clearly than CPU branding does.
Retest after every major camera or AI expansion
A surveillance system is not static. Camera firmware, bitrates, AI models, Blue Iris updates and remote-use patterns can change the workload over time.
Save the original calculator inputs and measured utilization. When the system grows, rerun the plan and compare real bottlenecks before replacing hardware.
Questions people ask
Blue Iris Hardware Calculator questions
Is this an official Blue Iris calculator?
No. It is a Cloudzat planning tool grounded in current Blue Iris published requirements. Compute tiers are directional; storage and network arithmetic use the values you enter.
How accurate is the storage calculation?
It is mathematically accurate for the entered average bitrate, recording fraction and retention. Real accuracy depends on how closely those inputs match the cameras.
Why does the calculator not name one exact CPU?
Blue Iris performance depends on codec, acceleration, AI, substreams, remote viewing and many other variables. A fixed CPU promise would overstate precision.
Why is RAM rounded upward?
Memory is bought in practical module sizes and Windows/AI need headroom. Standard tiers are more useful than a falsely precise number.
Can the calculator size a PoE budget?
It sizes port count. Exact PoE watts require the power specification of each camera, so the total budget must be verified separately.
Does the calculator assume continuous recording?
You can choose continuous or event-weighted recording and set the percentage of the day retained for event recording.
Does the calculator include audio?
The bitrate you enter should reflect the total stream you intend to record, including audio if enabled. Measure the real stream for best results.
Can I use the result for 4K cameras?
Yes. Choose the 8MP resolution option and enter the camera’s actual bitrate and FPS. Compute remains a planning tier, not a performance guarantee.
Does a 10GbE recommendation mean Blue Iris requires 10GbE?
No. It means the entered aggregate workload deserves a faster-network evaluation. Validate with measured traffic and the storage path.
What should I do after getting the result?
Shortlist exact products, verify CPU/GPU capabilities and drive/switch specifications, install Blue Iris, and test the complete workload during the evaluation period.
