Your CCTV recorded the fly tipping. The clip just doesn't have the number plate in it.

Because the saved clip almost never has both number plates in it. Standard motion-trigger alerts fire when bags hit the ground, but by then the van has already reversed in, the front plate is past the camera, and the rear plate is hidden behind the open boot. A council enforcement officer reading the clip sees the dump but cannot see the registration. The case dies on identification. The fix is to fire the alert on the parked vehicle, not on the dump action itself, so the saved clip starts before the van pulled in.

vehicle_dwell is an event class that fires when a detected vehicle stays inside a defined tile (a bin store, a rear yard, a service road) for longer than a configurable threshold. For fly tipping the typical threshold is 60 to 120 seconds at hours when no scheduled collection is on the calendar. Because the timer is counting up while the vehicle is still parked, the alert fires before the unload finishes, and the deep-linked clip on the recorder is seeked to iso8601_ts minus a small buffer. The buffer is what causes the saved clip to start before the vehicle entered the tile, capturing the front plate on approach. A motion trigger keyed on pixel change cannot do this because the pixel change happens at the moment of dumping, which is too late.

No. ANPR is a separate, expensive overlay that most properties cannot justify for a handful of incidents per year. The cameras you already have on the bin store and the service road already capture readable plates on the approach and exit, the missing piece is making sure the saved clip covers those moments. Cyrano plugs into the HDMI output of your existing DVR or NVR, classifies the multiview composite per tile, and triggers on vehicle_dwell using whatever cameras the recorder is already receiving. The saved clip is on the recorder you already own. If the camera resolution is good enough to read a plate to the human eye on the live feed, it is good enough for the clip.

Five frames in one continuous record: front plate on approach, vehicle parked in the bin store with the boot open, the act of leaving items behind, vehicle reversing or driving out, rear plate on exit. Plus a timestamp on the recorder clock (not the system clock, the recorder clock the council can subpoena), the name of the camera as it appears on the recorder's own multiview overlay, and the name of the property the camera is on. Cyrano's event record carries all of that as nine scalars plus a 480x270 thumbnail. The dvr_deeplink resolves to the underlying clip on the DVR, seeked, so the council officer can play it without you having to extract and email an MP4.

Two ways. First, schedule. The vehicle_dwell rule for the bin store tile is only armed during hours when no collection is on the calendar. For most multifamily and commercial sites that means 19:00 to 06:00 plus weekends. Second, the dedup key. Cyrano keys events on property + tile.label + event_class with a configurable cooldown window. A bin lorry that lands inside the armed window once a fortnight produces one alert that the on-call manager dismisses in five seconds, not a hundred. The recorded clip is still on the DVR if you ever need it.

Councils accept private CCTV evidence under the Environmental Protection Act 1990 Section 33 and the Clean Neighbourhoods and Environment Act 2005, provided the footage is unaltered, timestamped, and you can describe the recorder it came from. The Cyrano dvr_deeplink resolves to the original clip on the recorder, not a re-encoded copy, so the file you hand over is the same one the recorder wrote at capture. The event record carries iso8601_ts on the recorder clock, tile.label (the camera name as the recorder knows it), property, and a SHA-256 of the thumbnail. That is enough metadata for a council enforcement officer to take the clip and add it to a Section 33 file. Some councils will then issue a fixed penalty notice; serious cases go to the Magistrates' Court.

Both. Cyrano reads the HDMI output of the recorder, not the camera feeds directly, which means it does not care whether the DVR is analog (AHD, TVI, CVI) or IP (NVR over RTSP). A 25-tile multiview composite from any recorder looks the same to Cyrano. Fly-tipping cases are common on Class B/C apartment buildings, commercial yards, and housing estates that have older analog systems where buying new IP cameras is not in budget, and these are exactly the sites the HDMI capture pattern is designed for. No coax replacement, no recabling.

Median capture-to-phone latency is 7 to 8 seconds on a 25-tile multiview, with a 5 to 15 second envelope across the portfolio. That window includes HDMI capture, overlay masking on the recorder chrome, classification on the composite, multi-frame persistence, dedup against the cooldown key, thumbnail crop, and WhatsApp or webhook delivery. The number is recorded as latency_ms on every event so a regional manager can chart p50 and p95 per property without waiting for staff to notice missed alerts.

The companion event class is loiter, which fires on a person whose dwell time inside a tile exceeds a threshold, with the same buffer-before semantics on the saved clip. For walk-up dumping (a sofa on the verge, bin bags pushed over a wall) loiter at the bin store at unscheduled hours is the right trigger. Both vehicle_dwell and loiter write the same nine-field event record, so the alert body, the webhook POST, the dashboard row, and the deep-linked clip are identical in shape. The on-call manager triages from the lock screen the same way for both.

The DVR keeps doing whatever motion-triggered recording it was doing. Cyrano does not touch the recorder config and does not need RTSP credentials. What Cyrano adds is a parallel event channel that classifies the multiview, fires on vehicle_dwell or loiter at specific tiles during armed windows, and delivers a phone-triageable alert with a cropped thumbnail and a deep link to the clip on the DVR. Most properties end up disabling the DVR's own motion push within the first week because the new channel is acted on and the old one was muted.
