The detective asked Dad why the camera had recorded after being unplugged.

Dad explained the model had a rechargeable backup battery intended for brief outages.

Nothing secret.

The manual said so.

The camera also stored encrypted clips locally on microSD.

Again:

Normal feature.

Valerie simply did not know.

The manufacturer provided technical confirmation.

No hacking.

No hidden government access.

No miraculous cloud resurrection.

Power cord unplugged.

Battery engaged.

Recording continued.

That mattered to me.

The truth survived because of a mundane engineering choice.

A twenty-minute battery.

A memory card.

A device built for thunderstorms ended up documenting violence.

Dad later replaced the system.

Not because the old one failed.

Because every notification sound made him flinch.

The new monitor also had backup power.

We read the manual this time.

All of it.
