A line in Hikvision that is displayed on the screen but does not produce a usable event requires a check of the entire configuration. Direction, activation schedule, and alarm coupling are just as important as the position of the line. Work with a test passage whose time and direction of travel are known.
Read the camera and recorder model and note which channel the camera enters. Then determine where the chosen detection is set. A menu on the recorder can transmit camera functions or offer its own analysis. The manual for the specific combination determines what is possible; a similar pictogram does not prove equal capacity.
Draw the desired boundary line in a location where the full passage is visible. First test both directions of travel and compare them with the chosen direction. For a door that turns outward, the movement of the door should not continuously cover the passing person. If necessary, move the rule to a more visible part of the route.
Check the activation schedule and the set actions. Find the test time in the event list and then in the recording. Only then look at the app notification. If the notification is missing, it is not logical to redraw the image repeatedly. Check the recipient, permissions and notification settings on the used device.
Save the existing settings and note one adjustment per test. Test a normal visitor, a passage along the border, and a moment when no alert is desired. Check again in low light: headlamps and reflections change what is visible. Agree with the operator on which alerts require action and who may make changes.
That depends on where the analysis takes place and what the equipment supports. First note the models, firmware, and channel before changing settings on both devices.
No. A wrong direction, incorrect schedule, or missing connection cannot be corrected with this. Test the individual steps before adjusting sensitivity.
