Motion detection using infrared IR sensor beams.

radix9 — Fri, 23 Dec 2016 18:55:25 GMT

My system has an Arlo Pro base station and two cameras -- one Arlo and one Arlo Pro.

I need to know the simple facts about the IR (infrared) detector beams that the cameras employ to detect side-to-side motion (if in fact they do use multiple beams)..

1. How many beams does the camera use?

2. Where are the left and right edges of the multi-beam coverage (in degrees, please)?

3. What is the vertical width of the beams in degrees.?

All the instructions and comments I have read online merely tell how to struggle through the process.

I think I understand the process fully, but facts are few.

Does anyone know the answers to my 3 simple questions?

Thanks

1) The Arlo has a 110 degree field of view wuth ONE PIR device to detect motion ( that covers the entre FOV )

The PRO model has a 130 degree fov nad uses 2 PIR sensors to react quicker / more reliable , same covers FOV

2) the sensor matches the entire FOV above, tho on the Arlo it seems more sensitive on the outer edges, not so on the Pro

3) the arlo and arlo Pro are both 1280 x 720
