Indoor security cameras have become essential for monitoring pets, babies, and elderly family members. The Xiaomi Smart Camera C300 (小米智能摄像机C300) raises the bar with 2K resolution (2304×1296), 360° horizontal pan and 108° vertical tilt, and AI motion tracking — all at just ¥199 (~$27 USD) on JD.com.

With 100,000+ reviews on JD.com and a 97% positive rating, the C300 is one of Xiaomi’s most popular smart home products. Let’s see why it dominates the budget camera category.

Design and Build

The C300 is a compact 78 × 78 × 126mm white dome camera. The base houses the motor for pan/tilt, while the camera module (a black sphere) sits in a white housing. It looks friendly rather than intimidating — important for indoor cameras that shouldn’t feel like prison surveillance.

The microSD slot is hidden under the camera module (tilt it up to access). The camera supports cards up to 256GB — enough for about 10 days of continuous 2K recording or weeks of motion-triggered clips.

Installation is simple: plug in the USB-C power cable, connect to Wi-Fi via the Mi Home app (QR code pairing), and choose between desk placement or ceiling mount (screw holes and wall anchors included).

Performance

The 2K sensor delivers sharp, detailed video. You can read text on a phone screen at 2 meters and clearly identify faces across a room. The full-color night vision (using a supplemental white LED) produces surprisingly good color footage in near-total darkness.

AI motion tracking is the headline feature. When enabled, the camera automatically follows moving subjects — a person walking across the room stays centered in frame. The tracking is smooth and responsive, though it occasionally loses fast-moving subjects.

Two-way audio is clear enough for conversations. The speaker is loud enough to be heard across a room. There’s about 300ms of latency typical of Wi-Fi cameras.

What Chinese Users Say

Aggregated Ratings: 4.7/5 ★ (100,000+ reviews on JD.com, 97% positive)

“2K pan-tilt camera at ¥199 is incredible value. I use it to watch my dog — see what she’s doing during the day, AI tracking automatically follows her. Image quality is sharp, full-color night mode is bright too.”

“Using it as a baby monitor above the crib. Cry detection is sensitive — phone alerts the moment baby cries. Two-way audio lets me talk to the baby and soothe her. Six months with zero issues.”

“Great value but strong plastic feel. You can hear a slight motor noise when the lens rotates. But at this price, can’t ask for too much — functionality is more than sufficient.”

“Installed above the door — auto-records and pushes to phone when someone passes. Paired with Xiaomi hub, it can auto-activate lights at night when a person is detected, scaring off anyone suspicious.”

vs Competitors

vs Xiaomi C200 (¥129): The C200 is fixed-position and 1080p. The C300’s pan-tilt, 2K resolution, and AI tracking are well worth the ¥70 upgrade.

vs Xiaomi C500 Pro (¥349): The C500 Pro offers 3K resolution, pet detection, and NAS support. The C300 hits the sweet spot for most users who don’t need those premium features.

FAQ
