We installed large cameras, this is the reason for selling. The camera is amazing, it has a call feature and motion detection, you get a notification on your phone when someone passes by. It has a data SIM card installed, I have activated a plan for 115 per month. And I talk to the worker through it. Watch its videos on YouTube to see its other features before contacting us to save time and peace. Contact via private message only. (Phone number appears when you press the contact button) If you want videos and pictures of it or have inquiries, Contact the owner via WhatsApp only.
