Is event detection better with 24hr video?

Community Member

This a little convoluted so bear with me.

I have a new Nest Cam (battery) that isn't reliably detecting events until people are within 15 ft or so of the camera.  The camera itself can obviously see much farther than that, and do so with great clarity, but it isn't doing me any good if the camera only turns on when someone is right next to it. 

I've read posts like this one that talk about the cams on battery power going into idle mode and failing to detect events. It sounds like having them plugged in all the time would solve the idle mode issue and potentially improve event detection. That's one thing I can try.

I think  that event-based recording is triggered by the motion sensors. Right? I haven't been able to find the exact spec on this, but it seems the motion sensor range is less than 20 ft or so, which only covers about half the space that I'm hoping to monitor. So anything that happens more than 20ft away doesn't get recorded at all. 

That brings us to this: There's a lot in here, but the primary point I'm taking from it is that the calculation of whether or not an "event" has taken place happens after the camera has been triggered by the motion sensor to start recording. It's a separate step when programs analyze the actual video feed.

So for event-based recording, I think this is how it works: 

Step 1: The IR motion sensors detect movement and tell the camera to start recording.

Step 2: Google algorithms analyze the video feed and decide whether to record the event and send a notification.

Now I'm ready to ask my actual question. If you pay for Nest Aware and 24hr video, does that mean that the IR motion sensor is taken out of the equation because the camera is always recording? Or is that wrong, and Step 2 is still dependent on that motion sensor trigger even when the camera is recording 24/7? Theoretically, this could extend the range for event detection because it would based on video analysis rather than the range of the motion sensors.

Hi KcH89,


Thanks for reaching out! I appreciate you sharing your thoughts about this. 


Your camera can send alerts when it senses motion, picks up a sound, notices a person, and other activity. With a Nest Aware subscription, your camera can use advanced algorithms to improve its motion and sound detection and send you better notifications. 


Your camera can also notify you when it has technical issues. This can help you troubleshoot when your camera isn’t working as intended. Some camera alerts are always on to keep you informed about important events like when your camera goes offline, is removed from the app, or detects tampering. You can’t change settings for these notifications in the app.

I hope this helps.
