微控制器應用實驗室: Integrate Raspberry Pi, ESP32-CAM , ONVIF compliant cameras and Shinobi Software to build a Video Surveillance System

實驗目標：

以Raspberry Pi 3B+架設NVR系統，使用Shinobi free, open source software。
ESP32-CAM串流輸出MPEG video到NVR，儲存在硬碟中。
使用D-Link DCS-8300LHV2 Wi-Fi ONVIF camera儲存影音到NVR。
連續錄影與移動偵測錄影。

一、NVR系統架設步驟:

使用raspberry Pi 3B+板子，使用外接USB硬碟為儲存設備。

下載Raspberry Pi Imager，執行安裝Raspberry Pi OS。

選擇安裝Rapberry Pi OS Lite(32 bit)，Write to SD card

設定Rapberry Pi:

啟用SSH:
sudo raspi-config
Interface Options
SSH
設定固定IP:
$ sudo nano /etc/dhcpcd.conf

#static ip_address=192.168.1.23/24
#static routers=192.168.1.1
#static domain_name_servers=192.168.1.1
取消註解，並更改你要的 IP address
安裝Shinobi:
$ sudo wget https://gitlab.com/Shinobi-Systems/Shinobi-Installer/raw/master/shinobi-install.sh
$ sudo chmod +x shinobi-install.sh
$ sudo ./shinobi-install.sh

Shinobi - Do you want to temporarily disable IPv6?
Sometimes IPv6 causes Ubuntu package updates to fail. Only do this if your machine doesn't rely on IPv6.

設定連接USB HDD:
Raspberry Pi NVR外接1TB USB HDD採用NTFS檔案系統儲存攝影機影像。
a: 安裝Raspberry Pi NTFS software
$ sudo apt install ntfs-3g

b:列出外接USB HDD block device id，以便後續掛載Device
$ sudo blkid

/dev/mmcblk0p1: LABEL_FATBOOT="boot" LABEL="boot" UUID="5DE4-665C" TYPE="vfat" PARTUUID="347dad1e-01"
/dev/mmcblk0p2: LABEL="rootfs" UUID="7295bbc3-bbc2-4267-9fa0-099e10ef5bf0" TYPE="ext4" PARTUUID="347dad1e-02"
/dev/sda1: LABEL="TOSHIBA EXT" UUID="BA96216F96212CF7" TYPE="ntfs" PTTYPE="atari" PARTUUID="0f80c3ad-01"
/dev/mmcblk0: PTUUID="347dad1e" PTTYPE="dos"

c: mount USB HDD
# create mount point
$ sudo mkdir /mnt/nvr

#check shinobi running by which user
$ ps -aux | grep shinobi
pi 3548 0.0 0.0 7348 552 pts/0 S+ 02:33 0:00 grep --color=auto shinobi

# mount device
$ sudo mount -t ntfs-3g -o uid=pi,gid=root,umask=007 /dev/sda1 /mnt/nvr

#add the information need to mount the disk in fstab
$ sudo nano /etc/fstab
UUID=BA96216F96212CF7 /mnt/nvr ntfs-3g uid=pi,gid=root,umask=007 0 0

#add two directories esp32 and dcs8300 to store vedios
$sudo mkdir /mnt/nvr/esp32
$sudo mkdir /mnt/nvr/dcs8300

##login in shinobi super to add additional storages: esp32 and dcs8300，步驟請參閱文章最後影片展示。

安裝成功後，Shinobi 開啟畫面。

二、ESP32-CAM 攝影鏡頭設定:

開啟Arduino IDE，選擇開發版。
工具 >> ESP32 Arduino >> ESP32 Wrove Module
開啟範例檔:
檔案 >> 範例 >> ESP32 >> Camera >> CameraWebServer

註解//#define CAMERA_MODEL_WROVER_KIT
取消註解 #define CAMERA_MODEL_AI_THINKER
填入Wi-Fi SSID and Password
const char* ssid = "your-ssid";
const char* password = "your-passwd";

連接FTDI(USB-TTL)上傳範例程式
FTDI ESP32-CAM
GND GND
VCC 5V
TX UOR(IO3)
RX UOT(IO1)
上傳程式時IO0 接GND，上傳後拔除後按reset鍵即開始執行ESP32-CAM，Stream server Port為81，連接shinobi NVR時使用stream port。

測試web server，成功取得畫面
