CAM-403

A tree has come down the channel and is blocking the intake

Mid-morning at the intake channel. A fallen tree lies across the channel and its branches are pressed against the rack bays, mixed with bottles and plastics carried down by the water; only the section on the right is still clear. Upstream the water is still, with nothing moving. A crew member in a vest and white helmet is leaning over from the walkway, and up on the road a utility truck with a boom is parked.

What this camera measures

An alert says something is happening. The reading says how much.

The figures on this screen are an example from the illustration, not any client's measurement.

The rule

You decide once. IRIS applies it always.

a bulky object lodges across the racks in the channel

Then

open a critical alert for the on-call crew
save the video from when the object arrived in the channel
send the still with the camera, the affected bay and the time

The instruction that set it up«Tell me if something large lodges across the racks at the intake.»

What changes

What changes for whoever answers for the plant

With the intake blocked, inflow drops and the plant starts drawing on reserves. If nobody sees it, the alert comes when water runs short, not when the tree arrived. IRIS watches the channel around the clock and raises the alert as soon as a bulky object lodges across the racks, with the camera, the time and the video of the moment it arrived. The crew leaves knowing which machine is needed and goes out once.

What people usually ask

Does IRIS predict when debris is going to arrive?

No. IRIS does not predict: it alerts to what is happening. It sees the object once it is in the channel and raises the alert while it is happening, not on the next round. That difference is what separates a planned clean-up from a plant with no inflow.

Can it mistake the shadow of a tree for a tree?

The rules are tuned at the point itself, with that camera's real sun hours and framing. What counts as an alert is decided by the operator, not by the camera. And since every alert arrives with its video, reviewing it and dismissing it takes seconds.

Can the same camera count the floatables that arrive?

Yes, it is the same camera's other way of working. To count, you draw a line or a zone on the image and get a number by hour, by day and by season. To search for a situation, you write a sentence. Asking is for finding and counting is for measuring.

Other cameras

A different case every time

A camera looks. IRIS understands what it sees.

An extract of the real screen, no voice-over and hands-free. Each round poses another situation. What sits behind it is a good deal bigger than what you see.
