Installing motion
On ubuntu/debian/raspios motion can be installed with:sudo apt install motion
Once installed a configuration file will be created at /etc/motion/motion.conf
A minimal working configuration that defines two action hooks on motion detected — the hooks are used to post live video updates to your telegram chat (requires registering a telegram bot with the telegram botfather — see more on this below):
auto_brightness off
video_params input=-1 brightness=0 contrast=0 frequency=0 hue=0 saturation=0 power_line_frequency=-1
# !!!IMPORTANT: this sets the service to forking mode,
# when `on` you MUST use `Type=forking` in the systemd unit file
# located by default at /lib/systemd/system/motion.service
# if you use `daemon off` then set `Type=simple` in motion.service

Telegram hooks
To use telegram hooks you will first need to create a telegram bot:- open telegram.me/BotFather from telegram and send /newbot as a command to the bot and follow the steps. Once you assign a name and a username to your bot you'll get the bot token that will will look like 5432101234:XXXXXYYYYYYYZZZZZZZZZZZZZZZZZZZZZZZ where 5432101234 is your bot ID and XXXXXYYYYYYYZZZZZZZZZZZZZZZZZZZZZZZ is the SECRET TOKEN that you must not ever share with anyone!!! Make sure you save the bot token in a secure place.
- To get help on what telegram.me/BotFather can do enter /help in the chat window.
- Send any message to the group you have just created where your bot is already a member.
- Open the following URL in your browser: https://api.telegram.org/bot5432101234:XXXXXYYYYYYYZZZZZZZZZZZZZZZZZZZZZZZ/getUpdates (replace with your BOT_TOKEN!)
- In the JSON response locate the chat and under it the id subnode which will be a negative number. Please note down this chat id number because you will need to use it in your telegram hooks!
Let's assume the chat id value you got is -999999999 — this is the identifier for the group you created.
# /usr/local/bin/tg_send_alert_curl.sh
curl -X POST "https://api.telegram.org/bot5432101234:XXXXXYYYYYYYZZZZZZZZZZZZZZZZZZZZZZZ/sendMessage" -F chat_id="-999999999" -F text="$1: motion detected $(date '+%d-%b-%Y %H:%M:%S')"
👉 see https://core.telegram.org/bots/api#sendmessage
To enable markdown in your messages add -F parse_mode=MarkdownV2 to the command above.
For HTML mode use -F parse_mode=HTML — be aware than only a subset of HTML is supported.
# /usr/local/bin/tg_send_video_curl.sh
curl -X POST "https://api.telegram.org/bot5432101234:XXXXXYYYYYYYZZZZZZZZZZZZZZZZZZZZZZZ/sendVideo" -F chat_id="-999999999" -F video="@$1" -F caption="at $(date '+%Y-%b-%d %H:%M:%S')"
The two files must be made executable:
sudo chmod +x /usr/local/bin/tg_send_alert_curl.sh
sudo chmod +x /usr/local/bin/tg_send_video_curl.sh
⚠️ Important notes
The bot prefix right bebore your BOT_TOKEN is required — make sure it is there or otherwise the command will fail!
The $(date '+%d-%b-%Y %H:%M:%S') snippet generates a timestamp that will appear in your telegram notifications — feel free to remove it if you don't need it.
The $1 parameter in the first and second script will take the value passed in from the motion config file at /etc/motion/motion.conf — in case of tg_send_video_curl.sh this will contain the path of the recorded video file.
sudo systemctl stop motion
Once you updated the configs restart the motion service with:
sudo systemct restart motion
See the current status of the motion service:
sudo systemctl status motion
Display live logs (assumes you have log_file /tmp/motion.log in your /etc/motion/motion.conf):
tail -f /tmp/motion.log
