Good to know
Your Mac must stay open and awake; plugged in helps but doesn’t guarantee protection. Alerts depend on the internet and Telegram. NosyPup is not a certified alarm. Only use it where recording is allowed.
Yes. Alerts are sent through Telegram, using a private bot you create in a couple of minutes. The app walks you through it, including the BotFather part.
No. The camera needs to see, so your Mac must stay open and awake. Keep it plugged in for longer sessions.
No. Person detection happens on your Mac, and alerts go from your Mac to your own Telegram bot. Your photos and videos never pass through NosyPup servers.
NosyPup looks for people, which is designed to reduce false alerts from changing light and shadows. No detector is perfect, so you can also limit it to the area you care about.
