This Camera THINKS! Reolink Duo 3 + Home Assistant AI Vehicle Detection & License Plate Recognition!

Published at : 23 Dec 2025

With the power of the new ai_task AI vision features in Home Assistant paired up with the Reolink Duo 3 Wifi 16mp outdoor security camera, you can ask Google Gemini to identify vehicles in view, classify them by make and model, and even attempt automatic license plate recognition (ALPR)!

I’ll walk through the installation, integration, and setup so you can see exactly how this works. If you’re looking at Reolink cameras, AI-powered video analysis, or Home Assistant automations, this video will show you how to bring them all together into one powerful AI smart security system.

AI Prompt: Analyze this image for any vehicles seen in the driveway area. If no vehicles are seen in the driveway, then simply respond “No vehicles.” Only assess vehicles in the driveway area, nowhere else in the field of view. For each vehicle seen I want you to describe it using the following attributes: color, year, make, model, if you are able to read the license plate note the state that issued the plate and any or all of the characters on the plate that you are able to read, and then finally whether any business or government logos are visible and if so what they are. If the image appears to be in an infrared night-vision mode, do not attempt to assess the color of the vehicle. Format your response to start with the phrase "AI VEHICLE ANALYSIS:" and then start a new line. For each vehicle seen, enumerate through each of the requested attributes in the order listed above. Include one field on each line, but only if you have determined a value. If you are not able to determine a value simply skip the field. Format each line with the name of the field, the equals sign character with a space on either side of it, and then your assessment. Do not include any other information in your response. For the license plate, if you are only able to make out some of the letters and numbers, use the ? symbol for any character positions you are uncertain about.
