Camera not catching all vehicles...

Lemonchick — Sat, 06 May 2023 01:28:44 GMT

I'm going to search older posts here, but I finally had one of my cameras placed in front of my house. It sometimes catches vehicles, but does not catch all. For example, it has not caught my own vehicle driving past or even stopping in front of my house and my getting out to check the mail. It will record "vehicles" when you see nothing and then I have also had it record 5 minutes with nothing showing at the beginning to let me know what it started recording. My sensitivity settings are all the way up, so it should be catching everything. It also does not catch all people, like delivery drivers stopping and walking up to my door. Does anyone have any suggestions?

How far away is the camera from the street? Also about how far away is the camera from the people it is missing?

The camera uses a passive IR (PIR sensor) to detect motion, and the spec'd range for that is 25 feet. Vehicles can be detected from farther away, but not always.

In general, the camera is more senstive to motion across the field of view, so if the camera is aimed directly at a walkway, and someone walks up the middle of the field of view, it might be missed. It is also more sensitve at the bottom of the field of view than it is at the top.

You can test it with the motion detection test in the area where people are missed:

Likely a vehicle, or perhaps something blowing across the field of view. Sometimes objects move too quickly out of the field of view for the camera to capture what triggered the sensor.

There is a pre-roll feature (Arlo calls foresight) that would help with this, but it requires the camera to be connected to AC power.

Thank you! I think I got it fixed so the cars going by should be caught in the "capture area".
