Trigger siren only when people are detected - Arlo Pro 4

MTSH — Sun, 20 Mar 2022 08:21:27 GMT

Hi,

I am looking to activate siren on my Arlo Pro 4 and wondering if it could be triggered only when people are detected. Mode Rule only has the "Detects Motion" option and does not give the options similar to Smart Alerts (i.e. People, Vehicles, Animals and All Other Motion).

I get a couple of shots for cats each night (note: I do not get push notifications because Smart Alerts for Animals is turned off) and I do not want siren to be set off by them. Someone tried to break into a garage recently and I would like to have siren only for that type of events. Having options to select people/object would be very useful.

Another community thread talked about play with Motion Sensitivity but it sounds to me an error-prone process (i.e. siren might not get triggered when it should).

Any advice would be much appreciated.

It would be a nice feature, but at the moment Arlo doesn't have it.

One aspect is that the smart alert classification is done in the cloud, not by the camera. So there is a significant lag, which would limit any deterrence from the Siren.

The options are to

adjust the field of view as much as possible to remove unwanted objects/animals
adjust motion sensitivity (with the help of the motion detection test) - https://kb.arlo.com/41/How-do-I-change-the-motion-sensitivity-on-my-Arlo-camera

One trick that sometimes helps is to invert the camera (and apply the 180 degree rotation setting for the camera). Normally the camera is most sensitive to motion at the bottom of the field of view. If you invert it, that shifts to the top. That could be helpful here, as the animals are on the ground.

Thanks for your quick response @StephenB. Hope Arlo would consider adding this feature.
