How you can help!

• Vertical Tilt on the PANv2 doesn't work properly. Only does this on the modified kernel. Need investigation why this happens.

Why?

• Most things in life relate to cats somehow. I started this project to track the local feral cat population in my neighborhood using cameras.

Prerequisites

• Person
• Cat ( for emotional support during setup )
• Computer
• 256MB or larger Micro-SD Card is required!
• Higher class Micro-SD cards will ensure better performance

What Works / What Doesn't Work

• Everything works except:

  1. PAN v2:
     • Tilt (Vertical) only works at motor speed 9

HELP! SOMETHING DOESN'T DOESN'T WORK

• If you need assistance, or have general questions, feel free to visit the Discussions area! There are folks always willing to help out.

Setup v3/PANv2

1. git clone the repo or download the repo zip
2. perform a fresh format on your micro-sd card, using fat-32 ( this is a hard requirement, the bootloader does not support ex-fat or ext, and thus will not load wz_mini ), DOS partition map type, volume name does not matter.
3. copy all the files inside of SD_ROOT to your micro sd card
4. SSH is enabled, but is secured using public key authentication for security. Edit the file wz_mini/etc/ssh/authorized_keys and enter your public key here. If you need a simple guide, how to use public key authentication

Installation v3/PANv2

1. Turn off the camera
2. Insert the micro sd memory card into the camera
3. Turn on the camera
4. The camera will proceed to boot, then you may connect via the IP address of your device using SSH, port 22. The username is root. It may take a few minutes for the device to finish booting and connect to Wi-Fi, then launch the SSH server. Be patient.
5. You may also login via the serial console, password is WYom2020

Setup v2/PanV1

1. git clone the repo or download the repo zip
2. perform a fresh format on your micro-sd card, using fat-32 ( this is a hard requirement, the bootloader does not support ex-fat or ext, and thus will not load wz_mini ), DOS partition map type, volume name does not matter.
3. Run compile_image.sh using linux, wait for the script to finish.
   • PANv1: Run compile_image.sh pan using linux, wait for the script to finish.
4. Copy all the files inside of SD_ROOT to your micro sd card
5. Copy the generated demo.bin to root of your micro sd card
6. SSH is enabled, but is secured using public key authentication for security. Edit the file wz_mini/etc/ssh/authorized_keys and enter your public key here. If you need a simple guide, how to use public key authentication

Installation v2/PanV1

1. Insert the micro sd memory card into the camera
2. Hold down reset button while powering unit on. This is the standard manual firmware restore procedure.
3. Wait for camera to flash the latest modified firmware, and reboot, do not remove the micro sd card.
4. The camera will proceed to boot, then you may connect via the IP address of your device using SSH, port 22. The username is root. It may take a few minutes for the device to finish booting and connect to Wi-Fi, then launch the SSH server. Be patient. You should hear audio prompts from the camera once it has booted successfully.
5. If you have a car, you will now need to convert the camera to the car firmware. Use the car app to do this. After the conversion is complete, wz_mini remains active.
6. You may also login via the serial console, password is WYom2020

Removal

1. Delete the files you copied to the memory card, or remove the memory card all together. The next time you boot the camera, you will return to stock firmware.

Customization

Edit wz_mini.conf, this is stored on the micro sd card inside the wz_mini folder, and loads the configuration variables when the camera boots. You can change the hostname of the camera, add a path to a script to mount NFS, add ping commands, anything you like.

Wireguard:

Support is available as a kernel module

ENABLE_WIREGUARD="true"

Use the command wg to setup. See https://www.wireguard.com/quickstart/ for more info.

Some users have asked about tailscale support, I have tested and it works. See the issue #30 for further information.

Example setup:

ENABLE_WIREGUARD="true"
WIREGUARD_IPV4="192.168.2.101/32"
WIREGUARD_PEER_ENDPOINT="x.x.x.x:51820"
WIREGUARD_PEER_PUBLIC_KEY="INSERT_PEER_PUBLIC_KEY_HERE"
WIREGUARD_PEER_ALLOWED_IPS="192.168.2.0/24"
WIREGUARD_PEER_KEEP_ALIVE="25"

To retrieve the public key that you'll need to add the peer to your wireguard endpoint:

1. Use SSH to log in
2. wg

Disable automatic firmware updates:

DISABLE_FW_UPGRADE="true"

If a remote or app update is initiated, the camera will reboot due to the failure of the update. The firmware update should not proceed again for some time, or at all.

When a firmware update is initiated, due to a bootloader issue (bug?), we intercept the update process and flash it manually. This should now result in a successful update, if it doesn't, please restore the unit's firmware manually using demo_wcv3.bin on the micro sd card.

---

USB Ethernet Adapter:

ENABLE_USB_ETH="true"
ENABLE_USB_ETH_MODULE_AUTODETECT="true"
ENABLE_USB_ETH_MODULE_MANUAL=""

To have the Ethernet NIC be auto-detected and loaded automatically, set the ENABLE_USB_ETH_MODULE_AUTODETECT value to true.

To load a specific USB Ethernet NIC driver, set ENABLE_USB_ETH_MODULE_MANUAL to one of the following: asix, ax88179_178a, cdc_ether, r8152

NOTE: There is a possibility of a conflict between Ethernet NIC adapters that report themselves as PCI ID '0bda:8152'. (Realtek 8152 and CDC Ethernet) Since the 8152 is Realtek's product, that driver will be the one used for products that report that PCI ID. If you happen to have a CDC Ethernet product that uses that specific PCI ID, please set ENABLE_USB_ETH_MODULE_AUTODETECT="false" and set ENABLE_USB_ETH_MODULE_MANUAL="cdc_ether"

The next time you boot your camera, make sure your USB Ethernet Adapter is connected to the camera and ethernet. The camera has to be setup initially with Wi-Fi for this to work. After setup, Wi-Fi is no longer needed, as long as you are using the USB Ethernet Adapter. Note that using USB Ethernet disables the onboard Wi-Fi.

Network Interface Bonding:

BONDING_ENABLED="false"
BONDING_PRIMARY_INTERFACE="eth0"
BONDING_SECONDARY_INTERFACE="wlan0"
BONDING_LINK_MONITORING_FREQ_MS="100"
BONDING_DOWN_DELAY_MS="5000"
BONDING_UP_DELAY_MS="5000"

Bonding description is best described here: https://wiki.debian.org/Bonding#Configuration_-Example_2.28.22Laptop-Mode.22.29:

("Laptop-Mode")

Tie cable and wireless network interfaces (RJ45/WLAN) together to define a single, virtual (i.e. bonding) network interface (e.g. bond0). As long as the network cable is connected, its interface (e.g. eth0) is used for the network traffic. If you pull the RJ45-plug, ifenslave switches over to the wireless interface (e.g. wlan0) transparently, without any loss of network packages. After reconnecting the network cable, ifenslave switches back to eth0 ("failover mode"). From the outside (=network) view it doesn't matter which interface is active. The bonding device presents its own software-defined (i.e. virtual) MAC address, different from the hardware defined MACs of eth0 or wlan0. The dhcp server will use this MAC to assign an ip address to the bond0 device. So the computer has one unique ip address under which it can be identified. Without bonding each interface would have its own ip address. Currenly supported with ethernet adapters and usb-direct mode.

BONDING_PRIMARY_INTERFACE Specifies the interface that should be the primary. Typically "eth0".

BONDING_SECONDARY_INTERFACE Specifies the interface that should be the secondary. Typically "wlan0".

BONDING_LINK_MONITORING_FREQ_MS Specifies the MII link monitoring frequency in milliseconds. This determines how often the link state of each slave is inspected for link failures.

BONDING_DOWN_DELAY_MS Specifies the time, in milliseconds, to wait before disabling a slave after a link failure has been detected. This option is only valid for the miimon link monitor. The downdelay value should be a multiple of the miimon value; if not, it will be rounded down to the nearest multiple.

BONDING_UP_DELAY_MS Specifies the time, in milliseconds, to wait before enabling a slave after a link recovery has been detected. This option is only valid for the miimon link monitor. The updelay value should be a multiple of the miimon value; if not, it will be rounded down to the nearest multiple.

USB Direct:

ENABLE_USB_DIRECT="true"

the next time you boot your camera, make sure your USB cable is connected to the router. Remember, the camera has to be setup initially with Wi-Fi for this to work. After setup, Wi-Fi is no longer needed. Note that using USB Direct disables the onboard Wi-Fi. Change the MAC Address if you desire via USB_DIRECT_MAC_ADDR variable.

Connectivity is supported using a direct USB connection only... this means a single cable from the camera, to a supported host (An OpenWRT router, for example) that supports the usb-cdc-ncm specification. (NCM, not ECM) If you have an OpenWrt based router, install the kmod-usb-net-cdc-ncm package. The camera should automatically pull the IP from the router with most configurations. You can also use any modern linux distro to provide internet to the camera, provided it supports CDC_NCM. enjoy!

Note: In my testing, the micro-usb cables included with the various cameras do not pass data, so they will not work. Make sure you have a micro-usb cable that passes data!

---

Remote Accessories:

When USB Direct connectivity is enabled, the camera will be unable to communicate with accessories. To enable remote usb accessory support, enable the following variable and set the IP Address of the host as follows:

Scenario: Spotlight accessory needs to be located away from the camera, yet we desire spotlight control from within the app and camera. Plug the Spotlight into the nearby router running linux. Configure variables as below on camera, and run socat on the router. The app will now detect the spotlight accessory, just as if it was plugged in to the camera directly!

REMOTE_SPOTLIGHT="true"
REMOTE_SPOTLIGHT_HOST="0.0.0.0"

Then, run the following command on the host where the spotlight is attached to:

socat TCP4-LISTEN:9000,reuseaddr,fork /dev/ttyUSB0,raw,echo=0

Change /dev/ttyUSB0 to whatever path your accessory enumerated to if necessary. The camera will now be able to control the usb accessory.

---

USB Mass Storage Support:

ENABLE_USB_STORAGE="true"

If you would like to mount an EXT3/4 filesystem make sure to enable ext4 support:

ENABLE_EXT4="true"

---

CIFS is now supported.

ENABLE_CIFS="true"

---

iptables:

ipv4 and ipv6 available

ENABLE_IPTABLES="true"

---

NFSv4

ENABLE_NFSv4="true"

---

RTSP streaming:

The RTSP server supports up to two video streams provided by the camera, 1080p/360p (1296p/480p for the DB3 [DoorBell3]). You can choose to enable a single stream of your choice (HI or LOW), or both. Audio is also available. If you do not have RTSP_AUTH_DISABLE="true" MAKE SURE TO SET your login credentials!

NOTES

• ENC_PARAMETER accepts numbers only. 0=FIXQP, 1=CBR, 2=VBR, 4=CAPPED VBR, 8=CAPPED QUALITY. Currently only 2, 4, and 8 are working
• V2 and V3 endpoints are not the same!

RTSP_LOGIN="admin"
RTSP_PASSWORD=""
RTSP_PORT="8554"

RTSP_HI_RES_ENABLED="true"
RTSP_HI_RES_ENABLE_AUDIO="true"
RTSP_HI_RES_MAX_BITRATE="2048"
RTSP_HI_RES_TARGET_BITRATE="1024"
RTSP_HI_RES_ENC_PARAMETER="2"
RTSP_HI_RES_FPS=""

RTSP_LOW_RES_ENABLED="false"
RTSP_LOW_RES_ENABLE_AUDIO="false"
RTSP_LOW_RES_MAX_BITRATE=""
RTSP_LOW_RES_TARGET_BITRATE=""
RTSP_LOW_RES_ENC_PARAMETER=""
RTSP_LOW_RES_FPS=""

RTSP_AUTH_DISABLE="false"

Single Stream

the singular stream will be located at rtsp://login:password@IP_ADDRESS:8554/unicast

Multiple Streams

multiple streams are located at

• V3 - rtsp://login:password@IP_ADDRESS:8554/video1_unicast and rtsp://login:password@IP_ADDRESS:8554/video2_unicast
• V2 - rtsp://login:password@IP_ADDRESS:8554/video6_unicast and rtsp://login:password@IP_ADDRESS:8554/video7_unicast

You may disable authentication by setting RTSP_AUTH_DISABLE="true"

Setting the FPS is not required unless you want to change the default device settings (20 day/15 night FPS for V3, 15 day/10 night FPS for V2).

Note: If you don't set the password, the password will be set to the unique MAC address of the camera, in all uppercase, including the colons... for example:. AA:BB:CC:00:11:22. It's typically printed on the camera. Higher video bitrates may overload your Wi-Fi connection, so a wired connection is recommended.

Huge credit to @mnakada for his libcallback library: https://github.com/mnakada/atomcam_tools

mp4_write:

ENABLE_MP4_WRITE="true"

Forces the camera to skip writing files to /tmp, and write them directly to your storage medium or network mount, prevents trashing. Normally videos are written to /tmp then moved using mv, which can overload camera and or remote network connections. Useful for NFS/CIFS remote video storage.

Upgrade wz_mini over the air:

upgrade-run.sh

This script will upgrade wz_mini over the air. It will backup wz_mini.conf, any files stored in wz_mini/etc/configs, ssh keys, and wireguard configs. It will download the latest master version, extract it, reboot into upgrade mode, perform the upgrade, then reboot to the updated system.

If there are any line differences between the old wz_mini.conf and the new release, the script will preserve the current config in place. Note that this means any missing or additional lines. It is recommended to download the latest wz_mini.conf from github, if there are any major changes to the file, copy the new one to your system first, set your parameteres, save the file, then perform the upgrade.

NOTE: if you are upgrading a V2 camera from a release older than 06-16-22, you must manually download the upgrade-run.sh script from this repo and place it in wz_mini/bin/upgrade-run.sh, then run it from there !

---

FPS Drop during NightVision:

NIGHT_DROP_DISABLE="true"

Stop the camera from dropping the frame rate during nightvision.

---

WiFi Drivers (ADVANCED!!!):

Disable only if you know what you are doing.

ENABLE_RTL8189FS_DRIVER="true"
ENABLE_ATBM603X_DRIVER="true"

Enabled by default. These options control the WiFi Drivers. V2/V3 use the 8189fs.ko driver, and certain v3 models and all currently shipping pan v2 models use the atbm603x driver. These are required for operation of wz_mini, and disabling these will lead to a system crash, due to an updated kernel. This change was required to support full iptables and connection tracking operation, since they are not supported on the really outdated factory drivers. My testing shows better stability and performance.

---

Disable Motor Controls:

DISABLE_MOTOR="true"

Disable the movement capability on motorized devices. You will no longer be able to move the device from the mobile app, or command line. Best used to convert a motorized unit to fixed

---

File System Check/Repair:

ENABLE_FSCK_ON_BOOT="true"

During the repair process, the LEDs on the camera will flash RED-off-BLUE-off-PURPLE-off to inform the user the repair program is running. Once the program has completed, the LED will switch to RED, resuming the normal boot process.

---

Car Driver:

ENABLE_CAR_DRIVER="true"

Loads the appropriate driver for the car to function. On devices other than a V2 with the car firmware, the car may be controlled via car_control.sh on the command line. experimental!

car_control.sh defaults to high speed car_control.sh low_speed low speed car_control constant direction is constant, car keeps moving the direction you select without holding down any keys. car_control.sh constant low_speed like above, but in low speed

---
