Make A Security Camera With Python 

I think the best programming tutorial a youtuber can make is teaching how to read a module documentation efficiently and intuitively.

Tim, you are the best. I hope there will be continue of this series (at least part two): 1.) Manage files (delete records older than some period) 2.) Notification on e-mail about new record 3.) ... and more features with Python Tim, thank you for your RU-vid content! ;)

Me when my code doesn't run properly: 13:29 Me when my code does work: 13:28

To make your video start faster add this code to define some of the video parameters. It will cut the start of the video in half or more. cam=cv2.VideoCapture(1,cv2.CAP_DSHOW) cam.set(cv2.CAP_PROP_FRAME_WIDTH, width) cam.set(cv2.CAP_PROP_FRAME_HEIGHT,height) cam.set(cv2.CAP_PROP_FPS, 20) cam.set(cv2.CAP_PROP_FOURCC,cv2.VideoWriter_fourcc(*'mp4v'))

Too bad it's only regular face detection. It will never work as a security camera. The camera won't work in darkness or when a light is dim.

What module do I need to make the import command colour be red and not the pink colour it usually is

i literally just looked up how to detect motion with python on my 2nd monitor.... looked over on my 1st monitor youtube, and this video popped up!

How can it detect the difference between family persons faces and real theft persons??

The stuff you do for this community at no charge is just amazing. Thanks, Tim!

Does this work with a phone camera

Great video as always Tim, I cant even imagine how stressful it must be to try to code and explain, but just thought I mention that for future it might help to include comments on your code as it will help reduce the amount of explanation you would need to do, and is usually better practice right. Thanks again for your awesome content.

Great stuff. Possible bug on line 25.

This guy is one of the best developer in the world!

Python is very easy to record videos, But NoOne knows how to record videos with sound(

Its really good! Can you show how to creat a screen recorder in python

heey Tim great video, which is better : build our own classifier or use the built in classifiers for safety and robustness reasons like if someone is building a bank security system, and how can we use this open cv code to interact with a real camera like in banks, thanks budy

I need to come to America and get web developers job 🎗

I’m 43 yrs old and want to be as smart and articulate as this kid when I grow up

I would love to see you talk about using a camera wirelessly (for instance using a raspberry pi with an esp32 cam)

Could you add some code to detect somebody ‘s face and this give some output like opening a door???

Great video! One small bug: You are using the same cascade for body and face: faces = face_cascade.detectMultiScale(gray, 1.3, 5) bodies = face_cascade.detectMultiScale(gray, 1.3, 5)

Any idea on how to make it work where it doens't record YOU but everyone else?

Hey Tim can you please create a video on regular expressions in python

there is a mistake in your code, you are not detecting body, you are detecting twice faces.see row 24 and 25....

If you don't install pip, you can't do anything.

Hi amazing video like always but i have an error after writing { faces = face_cascade.detectMultiScale(gray, 1.3, 5) } if i remove this line it's works what should i do ?

Hey Tim, What is your Color Theme do you use? Mine are kinda boring I want to change to something and I think what you're using is gonna work.

How can we generate data from this program? For example to generate data in a database, location or how many different people where spotted in different time period?

THICC 32:08

i got this error when i run the program (cv2.error: OpenCV(4.5.3) C:\Users unneradmin\AppData\Local\Temp\pip-req-build-1i5nllza\opencv\modules\objdetect\src\cascadedetect.cpp:1689: error: (-215:Assertion failed) !empty() in function 'cv::CascadeClassifier::detectMultiScale').. i dunno how to solve it.. is anyone have idea for this?

Sir once we record the recording will be save to our local system. How can we upload or store the recording made by the webcam to cloud?

Do you have a tutorial showing how to set up visual studio code?

I can't download the module cv2 in Python :( ERROR: Could not find a version that satisfies the requirement cv2 (from versions: none) ERROR: No matching distribution found for cv2

my video is not saving :/ every time i exit the program it writes in terminal:: [ WARN:0] global C:\Users unneradmin\AppData\Local\Temp\pip-req-build-sn_xpupm\opencv\modules\videoio\src\cap_msmf.cpp (438) `anonymous-namespace'::SourceReaderCB::~SourceReaderCB terminating async callback can someone tell me how to fix

I get this error error: (-215:Assertion failed) !empty() in function 'cv::CascadeClassifier::detectMultiScale' dose anybody know how to fix it

Can you cover GPT4V for CCTV? Maybe good architecture for this since its expensive. Say its to 'monitor' your babies

It is such a shame, that this haar model is just garbage. It is better to train yours. Or you can use multiple models stacked together, like for eyes, nose, mouth and face and use the same principle behind haar cascading. Anyway great video.

i am getting an error with cv2.vediocapture shows an error ' vedio capture is not an attribute of cv2 , Open cv verison 4.6.0, please help me to resolve

excellent video, thanks for sharing, with that last statement regarding showing the video frame, i use a raspberry pi, could you set a key press that will show the current video, as if you wake up to a sound and hit the key to show the camera live view

i try this code and it's working but when it's started it automatically stop and start again even there's no person detected.. how to fix this?

Tim you're doing a great job!! Keep up the good work!!👍🏻

awesome stuff. i wrote a camera app in android but it is really hard. i got a camera in my roof that records things that fly over my house. i want to set up a python camera that will record only birds but the end goal is record ufos. that kinda script would be priceless for the ufo community.

when he creates a variable more than 10 letters long, you know his a legend

Could you please make a video on easing-functions?

Where do business save these video recordings usually? on a local server or in some cloud? if the cloud how do they connect the cameras to there?

I think I had complete the feature mention earlier in the vedio, but i will still follow this series to seek the better way of doing it.

Question what if camera detect a person wears mask like hiding his face does program start recording?

"this is your daily dose of internet"

dude i just wanna take ur blessing ahahahaha U ARE SO GOOD AT IT

Aren't we supposed to use body_cascade (for bodies) in line 23 ?

Tim, this is sooooo cool

The best Python guy that creates a social engineering tools

Line 17: resulting an error e.depth() == CV_8U in function 'cv::CascadeClassifierImpl::detectMultiScale'

my code wont stop recording when i leave the frame can anyone help me?

Can u make when u turn pc on to you get notification on phone that your computer turned on?

If i do it laptop, will it require external camera or not?

cap = cv2.VideoCapture(0, cv2.CAP_DSHOW) will open fast

i have a problem in line 23, i'm using Collab and it gives me this error : OpenCV(4.1.2) /io/opencv/modules/imgproc/src/color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function 'cvtColor

you are such a great explainer dude ! honestly the video is simple to understand , concise and very very informative !!! you helped me a lot !

I want to film my family dogs activities with this to see if he eat from his food bag when no one is around

It’s okay, but how can I transmit image by RTSP protocol?

what coding platform did u use, please I really want to do this and I love your vids

Hi How about audio How read video and audio together

Hello Tim, sorry, but nothing more than the many tutorials on this subject. I would have hoped from you that you would divide the screen for four cameras, that you say after 5 seconds start cam 1, the body is in front of cam 2 so it starts after the first one goes off if it detects a body. I would have wanted you to show how the video can take a photo when you detect the face ... ect but you still the best;)

files already have a date created why name it the same thing

Who misses this Tim who didn't make hyper-stimulating videos?

and why don't you show us how to connect the red bottom nat

hmm why in unpacking ure using _ , _ = x instead of just get this one like x[1]?

hello TIM you are the best youtuber/programmer python spesialist for me..i am a new programmer i lvoe python and i am making tons of your videos to practise and get any better in this..so if you can make a video of this camera project to make it even better?perhaps send an email notification on your phone or somethink like that? thx a lot

Import cv2 doesn’t work for me, what else can I do? I love your videos

Lol I put the timestamp generation + assignment to 'out' on the wrong side of the if/else conditions, and that caused a file to generate every few frames/every second in real time.

cv2 not found, even with installing multiple opencv's.

I have no idea what this guy is saying, but im really interested

I try to run the code, the light of my camera is on but I do not see any window pop up where I can see myself. Can someone please help me out

Tim, thanks for the example, very good.

What if I wanted to make a face ID thing, where my computer would do something when I enter it's camera?

just trying the code ,but im having issues. it cant read the haarcascase_fullbody.xml file. i erased my code and copy and pasted your code it works. ive seen this problem before.

I have a problem I don't know how to quit. Although I kept writing q in the terminal .

Nice .How can I run multiple camera using this code?

He confuses more than explain things, not the best video to watch

Thanks Tim... you are an amazing gent 🙏

it doesn't save the videos at the end of the recordings. I already checked in the folder when the code is saved.

What algorithm does this use?

it says cv2 does now exist? Can you please help me with this

Excellent video, thank you, so I have one question, can I do the same with an ip camera?

How can you change the resolution from the Video

Can you make a body tracer that gives same input as a keyboard? For example: if you lower your upper body to the right (keeping legs in the same place, facing the camera), this move would be equivalent to you pressing right arrow key. Is that possible in pure python?

what IDE are you using in combination with tabnine?

I followed along and got a working security program written in python, awesome thank you very much. I've just started learning Python but I've watched a few of your videos, the others being the python curses/ncurses tutorials, awesome videos and explanation of the examples. Thank you. *** how can I redirect where the video gets saved, as of now all files are saved in the directory where the script resides in, thanks.

Boss at first my program was not working but now it's working Boss... I really wanna be like you when I grow up

Make a video on Nintendo emulator in python it will be fun

...Read more

to end the delay of turn on the camera, jus do this: cap = cv2.VideoCapture(0, cv2.CAP_DSHOW)

Damn, that is some good stuff. That CV library looks comprehensive. Thanks for sharing!

Typo in line no 25

I had to fix the pipX install on my friends windows box, python nor was pip wasn't in the path & pipenv wasn't installed. The hardest part for me was trying to find out where python (& pipenv) lives on windows so I could just add them myself to the system environment. Once the windows system knows where python is, the Tim way works. I was thinking you should write a python module app script to try the various methods of install, then realised, you'd need to have installed that module to use it (segfault: redo from start lol)

Nice

after the opencv tutorials. this is just what i need

thank you so much

What about using a stream from an IP camera?
