The camera goes to the water when the sensor finds it

On June 20, 2026 the city sewer backed up into more than 60 units of my condo. Mine also came in through the foundation, gaps beside the electrical panel and a basement window, one week after I had finished rebuilding from my first flood. The mitigation report blamed heavy rain. The only thing that stopped it was two phone videos I took because I happened to be home. Watermark is the record I wish had been running.

My basement on 20 June 2026: water running down the wall under the window and spreading across the wood floor

Water came in under this window and ran across the floor

My basement, 20 June 2026, 4:35 PM, on a floor laid the week before. A phone photo, because nothing was recording.

My dining room on 5 December 2025: the ceiling opened up under a leaking bathroom, a blanket on the floor catching the water
The first flood, 5 December 2025: through the dining room ceiling. Again, only my phone was recording.

What Watermark keeps instead

  1. 0 s

    Water touches the sensor

    A Ring Flood & Freeze sensor fires. Watermark stores the event before anything else, because Ring keeps no history for sensor events.

  2. 6.85 s

    The camera goes to the water

    An Indoor Cam that already sees the room, or the rover carrying one down a tape line. Every frame carries Ring's time. 6.85 s is the median of my 10 measured Ring Playground runs, with a simulated sensor.

  3. When dry

    One pack, gaps included

    Timeline, frames, captions, humidity, device health, everything the record cannot vouch for, and a map against your insurer's questions. The cause is left to the adjuster.
