Added

  • On-screen event detection. A tile shows a coloured frame and a caption when its camera reports a target: HUMAN, VEHICLE or ANIMAL, followed by the kind of report (MOTION, LINE, INTRUSION, ENTER, EXIT), for example HUMAN - LINE. It listens to each camera's event stream (/ISAPI/Event/notification/alertStream), one shared connection per camera. Off by default.
  • Smart events. Line crossing, intrusion, region entrance and region exit reports show the frame as well as labelled motion reports. Plain motion with no target type never starts a frame, but keeps a showing one alive.
  • Cameras behind an NVR. KVision looks up each camera's own address from the NVR and listens to it with the NVR's login. These start off and are switched on one at a time.
  • Per-camera switch. Right-click a tile and choose "Detection frame" to turn it on or off for that camera. Switching it off closes that camera's connection at once.
  • Hold time setting (3 to 30 s) for how long the frame stays after the last report. The settings are under User Interface Settings.
  • Detection log. Every labelled report is written to logs/Detection.log in the configuration folder with the camera's own time, the target, the kind of report, the camera name and address, and the recorder and channel it plays back from. A report read 10 seconds or more late ends with received HH:mm:ss. logs/Frames.log records each frame a tile showed.
  • Detection log window. Right-click a Hikvision tile and choose "Detection log..." for the newest 10 entries, a "Load 10 more" button, a Refresh button and an "Only this camera" filter. Double-click an entry, or press its play button, to open playback 10 seconds before the event. A moment with no recording simply shows no video.

Changed

  • The routine libva info lines are hidden unless KVision is started with --verbose. A LIBVA_MESSAGING_LEVEL you set yourself is left alone.

Fixed

  • The frame is hidden by comparing the clock with the last report, not with one long timer: a 30 s one-shot timer was seen to fire after about 19 s.
  • A tile takes the camera's login from the saved recorder list. Using the tile's own password could send a blank one, which counts as a failed login and can lock a camera. The listener also stops for the session if a camera refuses its login.

Documentation

  • The README now says that on-screen detection depends heavily on correct detection settings inside each camera, and that setting them up takes attention to detail and patience.
