Enregistrement partiel

[frederic fusillier_236807380766857]

bonjour
je dispose d'une caméra reolink duo2 wifi, et les enregistrements sont partiels. En effet, j'ai des vidéos, de personnes ou de véhicules qui quittent mon domicile, mais pas de vidéos, de personnes ou de véhicules entrant dans ma propriété. Exemple, je me vois bien partir de chez moi aller faire des courses en voiture, et je ne me vois pas revenir...ou alors mon fils aller chercher le courrier, mais je n'ai pas de vidéo de son retour....
Donc pour être averti d'une intrusion, la caméra ne fait pas le job !!
Est ce un défaut de la caméra, un problème de paramétrage....

merci de vos retours
fred

@frederic-fusillier_236807380766857 Is this a battery operated DUO 2 or dc powered? Can you paste the Alarm settings (sensitivity and smart detection)?

@joseph_1979 c'est une duo 2 sur batterie. ci desous copie des écrans demandées. merci de votre aide

@frederic-fusillier_236807380766857 The alarm sensitivity set to 90 is good but having the sensitivity to 90 for the AI is high. I set it to 65 on my two WIFI DUO 2 battery cams. Note that these cameras use the PIR sensors which measures the infrared light radiating from the objects in its field of view.

In the link https://support.reolink.com/hc/en-us/articles/900000583003-What-is-PIR-Detection-Distance/ you can see the detection range for the digital PIR installed on the DUO 2. So if you set it at 90 then the maximum distance is around 10m. Note also that only the PIR is consuming current and the application is in cold state. So once the PIR detects a motion then it triggers the application to start executing and start the analysis of the object. This is why you don't get pre-recording video before the detetion unlike the dc powered cams which are constantly capturing.

With PIR cameras, one of the most important aspect is the orientation vis-a-vis the dectetion object. At a basic level, PIR sensors operate using positive differential change. A number of IR-sensitive slots sit in front of the lens, with their field of vision determining the range of detection. While idle, the ambient level of infrared detected in the room (naturally emitted by all objects) is the same on adjacent slots. The minute an object, person or animal moves through the detecting area, it is sensed by one of the slots before the other, causing a positive differential as it passes by, and a negative differential change as it leaves the area. However, if you approach the sensor within the same slot then there is no positive differential change and so it won't trigger the PIR. So ensure that you point it across the expected object movement.
