Creating a Django project to stream and store footage from an IP camera involves several steps. Below is a comprehensive guide to help you set up the project.
### Prerequisites
1. Python installed (preferably version 3.8 or higher).
2. Django installed (`pip install django`).
3. OpenCV installed (`pip install opencv-python`).
4. A compatible IP camera.
### Step-by-Step Guide
#### 1. Set Up Django Project
First, create a new Django project and an app within it.
```bash
django-admin startproject camera_stream
cd camera_stream
django-admin startapp streamapp
```
#### 2. Configure Django Settings
Edit `camera_stream/settings.py` to include your new app.
```python
INSTALLED_APPS = [
...
'streamapp',
...
]
```
#### 3. Create Models
You might want to create a model to store video metadata. Edit `streamapp/models.py`:
```python
from django.db import models
class VideoStream(models.Model):
title = models.CharField(max_length=100)
description = models.TextField(blank=True, null=True)
created_at = models.DateTimeField(auto_now_add=True)
video_file = models.FileField(upload_to='videos/')
```
#### 4. Set Up Media Files
In `camera_stream/settings.py`, add configurations for media files:
```python
MEDIA_URL = '/media/'
MEDIA_ROOT = BASE_DIR / 'media'
```
Update `camera_stream/urls.py` to serve media files during development:
```python
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
...
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
```
#### 5. Create Views for Streaming
Edit `streamapp/views.py` to create a view for streaming video from the IP camera:
```python
from django.shortcuts import render
from django.http import StreamingHttpResponse
import cv2
def gen(camera):
while True:
ret, frame = camera.read()
if not ret:
break
_, jpeg = cv2.imencode('.jpg', frame)
frame = jpeg.tobytes()
yield (b'--frame\r\n'
b'Content-Type: image/jpeg\r\n\r\n' + frame + b'\r\n\r\n')
def video_feed(request):
ip_camera_url = 'http://your_ip_camera_address'
camera = cv2.VideoCapture(ip_camera_url)
return StreamingHttpResponse(gen(camera),
content_type='multipart/x-mixed-replace; boundary=frame')
```
#### 6. Configure URLs
Update `streamapp/urls.py` to include the new view:
```python
from django.urls import path
from .views import video_feed
urlpatterns = [
path('video_feed/', video_feed, name='video_feed'),
]
```
Include these URLs in the main URL configuration in `camera_stream/urls.py`:
```python
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('streamapp.urls')),
]
```
#### 7. Create Templates
Create a template to display the video stream. Create a `templates` directory in your app and add a `video_stream.html` file in it:
```html
<!DOCTYPE html>
<html>
<head>
<title>IP Camera Stream</title>
</head>
<body>
<h1>IP Camera Stream</h1>
<img src="{% url 'video_feed' %}" width="800" height="600">
</body>
</html>
```
Update the view to render this template:
```python
from django.shortcuts import render
def index(request):
return render(request, 'video_stream.html')
```
Update `streamapp/urls.py` to include the index view:
```python
urlpatterns = [
path('', index, name='index'),
path('video_feed/', video_feed, name='video_feed'),
]
```
#### 8. Storing Video Footage
To store footage, you can modify the `gen` function to save frames to a video file:
```python
import cv2
def gen(camera):
fourcc = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('media/videos/output.avi', fourcc, 20.0, (640, 480))
while True:
ret, frame = camera.read()
if not ret:
break
out.write(frame)
_, jpeg = cv2.imencode('.jpg', frame)
frame = jpeg.tobytes()
yield (b'--frame\r\n'
b'Content-Type: image/jpeg\r\n\r\n' + frame + b'\r\n\r\n')
camera.release()
out.release()
```
### Running the Project
1. Apply migrations to create the database schema:
```bash
python manage.py makemigrations
python manage.py migrate
```
2. Create a superuser to access the Django admin:
```bash
python manage.py createsuperuser
```
3. Start the development server:
```bash
python manage.py runserver
```
Visit `http://127.0.0.1:8000/` to see your streaming IP camera video.
### Additional Enhancements
- Implement authentication to secure the stream.
- Add functionality to start/stop recording manually.
- Improve error handling and add logging for better debugging.
This setup should provide you with a basic Django project that streams and stores footage from an IP camera.
