Introduction

Image sensors are so cheap now, they can be deployed in extremely large number at ultra low costs. Increasing your data gathering capability substantially, providing you with greater insight, improved security, extra income etc.

With your own Private Cyberspace you can even use your Camera Stations to monitor yourself to answer previously difficult questions with absolute privacy:

When were the last TEN times you have wore that dress ? (the camera can be OUTSIDE your home).
When were the last TEN time you have visited the toilet ? (the camera is OUTSIDE the toilet door)

Camera Station 2023.1 comes with a OV2640 base camera onboard, to give your Private Cyberspace "eyes" at ultra low cost.

Activity Marker

You can (should) use your Camera Station as an Activity Marker, the recommended position is plugged into wall power socket, placed under a window with the camera facing the entrance (door).

Camera Firmware

The recommended firmware is esphome, but we have also listed others we have tested.

with different cable lengths 21mm to 75mm

camera

Note esp32 based PCCs used the Digital Video Port (DVP) standard while the raspberry pi based PCCs uses the Mobile Industry Processor Interface (MIPI). Luckily most camera modules supports BOTH out of the box :)

OV2640 - resolution 1600 × 1200
OV5640 - resolution 2592 x 1944

2. Many Extra Options

We have listed some controller cameras here as reference implementations below, but there are MANY different models available from MANY different manufacturers. For example, below are just some models from one range (T-Camera) from one manufacturer (LILYGO):

with Front Normal camera - AU$34
with Front Fish Eye camera - AU$40
with Rear Normal camera - AU$35
with Rear Fish Eye camera - AU$40
with Rear Normal Movement camera - AU$49
with Rear Fish Eye Movement camera - AU$49

"Movement" above means it has a MPU-6050 module with 3 Axis Gyroscope + Accelerometer

AI-Thinker Camera

The AI-Thinker Camera is the 2023.1 reference Camera Station.

pcc5

A ultra low-cost wifi camera with flash light, TF card storage and option for external antenna.

esp32cam

The top board is double sides (as shown above) with all the important functions.

1. Flash Light

The white LED flash light on the top board faces the same direction as the camera, providing illumination for the camera or the surrounding.

2. External Antenna

External antenna can be attached to increase radio range, by changing the resistor placement.

antenna

A large number for antenna types are available.

antenna1

We will be focusing on the ESP32-CAM here.

esp32cam

which normally comes with a OV2640 image sensor capable of 2 megapixels (1600x1200):

1600×1200 @15fps
800x600 @30fps
352x288 @60fps

There are many lens available, normally it is bundled with a len with 66 degree field of view. Different angle lens are available 24, 30, 120, 160, 200 etc.

3. Firmware

3.1. ESPHome

Program camera with ESPHome so it can be controlled from Home Assistant (Device Node) and send video Frigate backend for recording and image recognition purposes.

ESP32 Cam / ESP Home / Frigate - Configuration - Home Assistant Community

3.2. Tasmota

https://tasmota.github.io

Tasmota Firmware

The simplest way is to flash using Tasmota Web Installer and select tasmota32-webcam from the drop down menu.

TasmotaTemplates

There are Tasmota templates for many common webcam devices, for example:

Tasmota Image URL

http://DEVICE_IP/snapshot.jpg
Example: http://172.27.105.237/snapshot.jpg

Tasmota RTSP URL

Navigate to the ESP32-cam webUI and then go to the Console and enable the RTSP server by entering the following command:

WcRtsp 1

Now, the video stream should be accessible via using the following addresses:

rtsp://DEVICE_IP:8554/mjpeg/1

Example: rtsp://172.27.105.237:8554/mjpeg/1

Tasmota LED Patch

Navigate to the ESP32-cam webUI and then go to the Configuration -> Configure Other -> in the TEMPLATE field, copy and paste the following

{"NAME":"AITHINKER CAM inc LEDs","GPIO":[4992,1,1,1,416,5088,1,1,1,1,1,1,1,1,5089,5090,0,5091,5184,5152,0,5120,5024,5056,0,0,0,0,4928,320,5094,5095,5092,0,0,5093],"FLAG":0,"BASE":2}

Click on the Save button and the board will be rebooted.

If successful, the Toggle button and the slider to determine the brightness of the LED will be displayed.

LILYGO TTGO T-Camera

GitHub - Xinyuan-LilyGO/LilyGo-Camera-Series: 🔰 Compatible with all TTGO camera products

This is a very small yet featureful PCCC with battery charger, microphone, infra-red detector, OLED display.

console-controller

While the highly integrated LILYGO TTGO T-Camera is very cool, as of 2023-04-23, it is MORE expensive than the "supermarket" mobile phone below, making it a niche solution.

cheap_mobile

Low end mobile phones make the best sensors in a lot of cases. Even "supermarket" mobile phones at AU$47 (as of 2023-04-23) has a lot of features like touch display, rechargeable battery, camera, microphone, satellite positioning etc.

Body Camera

While body cameras are a bit over the top for everyday collection of data into your Private Cyberspace, they can improve the care of people with disability substantially when combined with advanced Private Cyberspace features.

For example, traditionally it is very expensive to provide care those people disability that requires 24/7 monitoring (e.g. those with severe autism). With their own Privacy Cyberspace, people's privacy can be preserved and the costs keep low, no matter high intensive the monitoring is.

Camera Stations can provide light-weight small-size sensors that can be attached to baby to enable remote monitoring by human or artificial intelligence.
