This is NOT a Graphics Card

The easier solution is to get motion detectors (as the video mentioned) and then just hire a journalism major (JM) to walk around and flap his arms to keep the sensors active.

This serves several functions:

 

(1) Keeps riff raff (like journalism majors) off the streets

(2) Easier to implement

(3) no worrying about e-waste cluttering up the landfill. When you wear out one JM, throw them away and get another.

Piece of cake

Yeah.... I don't know, I wouldn't be comfortable knowing that every inch of my house is being watched by cameras. Even if nothing is logged the cameras are there and the images can be accessed. That basically means there is no privacy from Linus in the house. (He would be able to get access to the camera feed any time he wants to) while his kids might not mind that now, I am not sure what they'll think about that once they turn teenagers...

I get why this feels so cool and exciting, but this can be abused so badly. This is one of the things that I feel are the wrong way to go with technology. I would've taken the cellphone route simply because this would make it possible to opt-out of it anytime I don't want to be tracked.

Yeah me neither.

Two potential problems:

1) Getting enough camera coverage to be able to see a face.

2) The models don’t work as well in low light.

Just a heads up, the path that was previously hidden, is showing at this moment.

I'd like top do this in my home to use facial recognition to disable my alarm as I'm always forgetting! Any detailed instructions?

[Hobox]

How much does something like this cost? Did I miss a mention in the video? Didn't see any rough numbers when googling

As someone who works in building-automation sector this is very interesting. Presence detection such as "how many people are in a room" is not easy (=cheap). For just presence detection there are sensor available that detect people that are sleeping or sitting at a desk working.

Some fairly good sensors for these purposes are made by a company called "Steinel". Their products such's as "HPD2" and "True presence".

The "True Presence" detects people even if they are still.

The "HPD2" is a camera that locally analyzes picture and gives out information if it detects people. It can also give out the number of people detected.

So I urge you to check those out. They are not cheap by any means!

I wrote some face detection software a decade ago with opencv for my bachelors degree. Had to do some trickery, to be able to run in real time on a dualcore.

 

From my experience from back then:

• The camera has a huge impact, not because of picture quality, but because of speed. Most webcams create a framebuffer in the camera beforce starting sending pictures to the computer. This creates lag. I settled with the playstation eyeToy because it was fast. Be careful in your choice of camera.
• You dont need a high resolution for object detection. 320x240 was enough for face detection for me. Face recognition might need some more. This saves a LOT of processing power AND increase privacy a little.
• Greyscale pictures are enough for object detection in most cases.

The goal here is to save energy and create convenience. Even if it is "only" 52W for the card, I would try to reduce the consumption with a lower picture resolution and less FPS. It is 52W 24/7. I would recommend testing it with greyscale images and what resolution you actually need for your cameras to work, just to save money and energy.

Think this project might be doable with a single $40 M.2 TPU.

 

For HVAC efficiency, a much lower polling rate would be fine - perhaps poll every minute, but turn off HVAC if no person is detected in the last 15 mins. Further, person detection might work acceptably with much lower resolution snapshots possibly as low as 100x100

Easier solution:

 

Set your alarm to the loudest volume it'll do.

Tune the alarm to the musical genre you hate the most.

 

I guarantee you will never forget to turn the alarm off again.

Anyone got links to all the software he is using? I am very interested in this type of real world, locally hosted, open source, application for AI but the video glosses over a lot of the particular software in use.

[Nystemy]

A lot of AI workloads can be made far more efficiently with regular code. There is however certain things that an neural network is the easier solution compared to making code. _{(Generally anything that is sufficiently complex for one to not logically figuring out any suitable way to approach the problem logically. This simple "check" is however not indicating that a neural network is suitable for the application, the programmer/development-team can just be dumb/unskilled and not know how to approach the problem logically to start with.)}

 

However doing detection of people in a room is an interesting application.

 

And to be fair here, I don't think a camera is needed. Motion sensors goes a long way, if you detect motion in a room, and it disappears without causing motion in any other room, then the person is still in the room, or they climbed out the window like a freak. This however is less applicable if there is multiple people in the house, and counting people is a bit harder especially if one's motion sensors aren't indicating direction. _{(Though, I have worked with IR motion sensors that trigger if one sits still a few meters away and just breaths, or slowly shift one's position. A person sleeping isn't a problem here. So general presence isn't hard to detect.)}

 

Going the full AI route seems a bit like hammering in a screw, or in this case, being excessively lazy and not thinking about how to implement something with a few hundred lines of code. _{(Though, there is other advantages with image detection and tracking of people, but that isn't really useful for general HVAC applications.)}

What cameras are being used? 

[MultiGamerClub]

Damn i should have gone for the ROG STRIX 3090 WHITE instead because damn that card looks better than the SUPRIM X 3080 TI i have..

[dogwitch]

it scary to see you with out a beard.

where going to leave this video at that...

[matt tech]

re detecting people in your house.

In a venue we manage we was looking into something similar. With high bay lighting you can get a microwave sensor. These sensors detect if someone is in the room even when they are not moving. Maybe it can be adapted for your home application.

I am also curious about this. Last I remember he was running ubiquity cameras, but I’m not sure if that’s still the case. 

[Required]

Thankfully I am not the only one who is concern about privacy!
I would NEVER place a Camera, Mic,... in my Apartment! The Webcam in my case is face to the ceiling.

That transition at 9:26 was smooth.

Props to @Aprime

Hey everyone, I'm David, the creator of Double Take, one of the open source projects featured in this video. It was an honor to see Linus use my project and I'm happy to answer any questions if anyone has issues getting Frigate or Double Take to run. You can also message me on Discord if that's easier too!

As demoed in the video, MANY thousands of dollars. The featured AI accelerator alone is over $1k.

 

Granted, if engineered to a more reasonable price point, you could use the $25 M.2 version in an unpopulated M.2 A+E slot of a spare PC, and have similar results at a fraction of the cost and power consumption.

Another more affordable home solution is using a thermal camera and ESP32 board to detect a heat signature. Much cheaper, more power efficient, and less invasive, but wouldn't be able to detect specific people, and could potentially have issues in environments with existing variable heat sources.
