Installation planner
The network & power plan
Use maximum power ratings and capacity available to this project.
Use the rated maximum, including IR, heaters or PTZ movement.
Combined maximum power of access points and other PoE devices.
One powered port per additional device; uplinks are separate.
Extra power budget above the total device maximum.
Total usable PoE output budget, not the switch AC rating.
Powered ports available to this project, excluding reserved ports.
Allowance for bursts, protocol overhead and extra traffic.
Usable link capacity shared by these camera streams.
Check per-port PoE standards and recorder throughput separately. A capacity PASS does not certify equipment compatibility.

Transparent assumptions.
Practical estimates.
Power budget and port count are separate checks
Use maximum device power, including night illumination, heaters and moving parts. Average daytime draw may understate demand when all cameras switch to night mode. The total PoE budget is the switch's available power output to devices, not its AC input rating. A switch can have enough ports but too little total power. Each port must also support the device's required PoE standard and wattage; this planner does not certify per-port compatibility. Reserve uplink ports separately.
Formula / method
Camera PoE W = camera count × maximum watts/camera
Recommended PoE budget W = (camera W + other device W) × (1 + headroom % ÷ 100)
Required powered ports = cameras + other PoE device ports
Units: Mbps = 1,000,000 bits/second; 8 bits = 1 byte. 1 GB = 1,000,000,000 bytes; 1 TB = 1,000 GB. W measures power; Wh measures energy. Values are calculated without intermediate rounding. A displayed estimate is not a guarantee.
Eight cameras at 12 W plus two access points using 20 W total draw up to 116 W at the devices. With 25% headroom, budget 145 W and 10 powered ports. A 120 W switch fails the selected headroom target even though it exceeds the raw 116 W device load.
Before you specify.
Does total budget prove each port can power a camera?
No. Check the camera and switch PoE standards, per-port watt limits, cable losses and any power allocation rules. Total watts and port count are only two parts of a compatible design.
Should uplinks count as camera ports?
The required port result counts powered devices only. Enter powered ports actually available to the project after reserving any shared uplinks or management connections.
Does the power headroom also increase UPS load?
No. Headroom is reserved capacity, not consumed power. The UPS estimate uses maximum device loads plus your recorder, switch base and loss allowance. It does not add the unused PoE headroom again.
