Clearer Security with 2.5K 4MP Resolution

The Xiaomi Smart Camera C400 uses a 4MP image sensor to record at a resolution of 2560 × 1440 pixels. Its 2.5K video delivers more visible detail than conventional 1080p indoor cameras, making faces, movements, furniture, and room activity easier to recognise.

A large-aperture design combined with a 6P optical lens helps reduce unwanted light refraction and improves image clarity. This makes the camera suitable for monitoring important indoor areas where detail matters, including nurseries, entrances, living rooms and small offices.

360° Pan and Tilt Room Coverage

Monitor a wider area without installing several fixed cameras. The dual-motor pan-and-tilt mechanism allows the camera to look left, right, upward and downward.

• 360° horizontal rotation

• Approximately 106° vertical viewing angle

• Remote directional control from the Xiaomi Home app

• Wide panoramic monitoring from a single position

Place the camera in a central location to monitor most of the room while reducing common blind spots.

AI Human Detection and Automatic Tracking

Instead of notifying you about every minor movement, the Xiaomi Smart Camera C400 uses AI-based detection to recognise human shapes more accurately.

When human detection and tracking are enabled through the app, the camera can:

• Identify human movement

• Follow a person moving within its viewing area

• Send activity notifications to your smartphone

• Reduce alerts caused by lighting changes or small moving objects

• Record important activity for later review

Human detection may need to be enabled manually in the Mi Home/Xiaomi Home app during setup.

Night Vision Without a Distracting Red Glow

Continue monitoring the room after the lights are turned off. The camera uses 940nm infrared illumination to provide night-time visibility without producing the noticeable red glow found on many conventional security cameras.

This makes it particularly suitable for bedrooms and nurseries because the night-vision system is less likely to disturb sleeping children or family members.

The camera automatically adjusts between normal daytime monitoring and infrared night mode according to the available light.

Real-Time Two-Way Voice Calling

A built-in microphone and large-diameter speaker allow you to communicate through the camera using your phone.

Two-way calling can be used to:

• Speak to children or elderly family members

• Check on household staff

• Communicate with someone in another room

• Talk to pets while away

• Give quick instructions to people at home

Smart microphone noise reduction helps make conversations clearer. Audio pickup performance can vary depending on room size, background noise and camera placement.

Dual-Band Wi-Fi Connectivity

The Xiaomi Smart Camera C400 supports both 2.4GHz and 5GHz Wi-Fi networks.

A 2.4GHz connection generally provides wider coverage through walls, while 5GHz can provide faster transmission with less interference when the camera is positioned closer to the router.

Dual-band support gives you greater flexibility when setting up the camera in homes, apartments and offices with multiple connected devices.

Efficient H.265 Video Recording

The camera uses H.265 video encoding, which provides efficient video compression while maintaining high-resolution image quality.

Compared with older H.264 encoding, H.265 can reduce the bandwidth and storage space needed under comparable recording conditions. This helps provide:

• Smoother remote playback

• More efficient microSD card usage

• Reduced network bandwidth consumption

• Longer recording capacity on compatible storage

Actual storage duration depends on recording settings, activity frequency, video quality and microSD card capacity.

Local and Cloud Storage Options

The Xiaomi Smart Camera C400 supports flexible recording options.

MicroSD Card Storage

Install a compatible microSD card of up to 256GB for automatic local loop recording. When available storage becomes full, older recordings may be replaced by newer footage according to the selected recording settings.

Cards with a capacity of 64GB or higher may need to be formatted through the camera before use.

Xiaomi Cloud Storage

Cloud recording services may also be available through the Xiaomi Home app. Cloud plans, free trial availability, recording duration and subscription charges can differ according to the selected Xiaomi account region.

A microSD card and paid cloud subscription are not necessarily included with the camera unless specifically stated in the product package.

Privacy and Data Protection

The C400 includes multiple security features designed to protect camera footage and account data.

• Integrated Xiaomi Security Chip

• Encrypted data transmission

• AES-128 cloud encryption

• Customisable camera sleep times

• Secure control through the Xiaomi Home account

Custom sleep schedules can be useful when monitoring is not required during certain hours.

For better security, use a strong Xiaomi account password, keep the app updated and protect your home Wi-Fi network with modern encryption.

Smart Home and Voice Assistant Support

The camera can work with supported Google Home and Amazon Alexa devices. Once configured, compatible smart displays may be used to access the camera view through voice commands.

A separate compatible Google Assistant or Alexa device is required. Feature availability may vary according to device model, Xiaomi account region and smart-home platform support.

Flexible Flat or Inverted Mounting

The Xiaomi Smart Camera C400 can be placed on a table, shelf, cabinet or other stable flat surface. It also supports inverted ceiling mounting using compatible mounting accessories.

When installed upside down, image rotation can be corrected in the Xiaomi Home app.

For the best monitoring results:

• Place the camera where furniture does not block the lens

• Keep it within reliable Wi-Fi range

• Avoid pointing it directly toward bright windows

• Install it close to a suitable power source

• Keep it away from water, steam and excessive humidity

The C400 is an indoor camera and should not be exposed to rain or outdoor weather.

1. Download the Mi Home/Xiaomi Home app.

2. Connect the camera to its power supply.
