Security Camera Upgrade Readiness Checker

Mark every statement that is currently true. The tool separates upgrade pressure by subsystem so you can replace the bottleneck instead of rebuilding a healthy system.

Use measured facts. Verify playback, disk status, PoE watts and real night footage before checking a box.

Critical cameras provide the detail needed at the real target distance. Night footage preserves usable faces/plates without severe blur or overexposure. Recorder has at least 20% spare channel capacity for planned growth. Current storage meets the required retention window with headroom. Recorder disk health is normal and recent playback has been verified. PoE switch has spare powered ports for planned wired cameras. PoE budget has at least 20% margin under realistic nighttime load. Switch/NVR uplinks are not congested and show no recurring packet-loss symptoms. Evidence-critical cameras are not dependent on unstable Wi-Fi. Evidence-critical cameras are not limited by battery recharge/solar availability. Recorder, switch and network have adequate backup-power runtime for the required outage. Camera/NVR firmware and hardware revisions are still supported for the features you need.

Complete the checklist, then score the system.

How to interpret the result

Camera/image pressure

Detail or night failures point toward lens/FOV, lighting, shutter or camera upgrades—not automatically the recorder.

Recorder/storage pressure

Channel, retention or disk-health failures point toward storage expansion, drive replacement or a larger NVR.

Network/power pressure

Port, PoE, uplink, Wi-Fi, battery or UPS failures point toward infrastructure before megapixels.
