Preparation of the camera for first activation

Before setting up Xiaomi Mijia CMSXJ11A Make sure you have everything you need:

• 📱 Smartphone with Mi Home app installed (version no lower than 6.5.400).
• 🔌 Power supply: The camera is operated by 5V/2A (You can use a smartphone charger).
• 📶 Stable Wi-Fi with 2.4GHz support (5GHz not supported!).
• 🔧 Fixing elements (if you plan to install on the wall or ceiling).

The first inclusion can cause difficulties, if you do not take into account a few nuances:

Once connected to Wi-Fi, the camera will automatically update the firmware (if a new version is available). Don't turn off power at this point, the process can take up to 10 minutes. For how to check the firmware version and manually update it, see the next section.

Firmware Update: Why It Matters and How to Do It Right

Firmware CMSXJ11A It affects the stability of work, image quality and availability of new features, such as older versions. 1.4.6_0032 support ONVIF, This allows the camera to be integrated into third-party surveillance systems (e.g. Synology Surveillance Station or Blue Iris).

To check the current version of the firmware:

1. Open the Mi Home app.
2. Go to the camera settings (Device) → Settings → About the device).
3. Find the firmware version line (for example, 1.4.6_0032).

If an update is available, the system will prompt you to install it, but sometimes the automatic update will freeze or fail to show the current version.

Download the latest firmware from [this forum](https://www.xiaomifirmware.com) (Choose tagged files"CMSXJ11A")

Unpack the archive and rename the file to digicap.dav

Copy the file to a microSD card (format) FAT32)

Insert the card into the camera and restart it (turn off/on power).

Wait for the update to complete (the camera will emit a long beep)-->

⚠️ Note: Do not use firmware from other camera models (e.g, CMSXJ20A or CMSXJ03CM) — This will lead to a "brickle" device, and also avoid interrupting the refresh process: if the indicator on the camera flashes red, wait until it turns green.

After updating to version 1.5.0_0045 And above, the camera has a hidden feature called Night Vision Pro, which improves detail in total darkness by using hardware to process IR radiation, which can be activated through the engineering menu (see Hidden Settings section").

Basic image settings: how to achieve a clear picture

By default, the camera CMSXJ11A It uses automatic settings that are not always optimal, such as when bright light can trigger excessive exposure, and when dusk, you can make noise.

The main parameters of the image are in the menu:

Mi Home → Device → Settings → Camera settings → Image quality

Recommended values for different scenarios:

Pay special attention to adjusting the white balance. In automatic mode, the camera can make mistakes, especially in artificial lighting. 4000K for warm lighting or 6500K day-time.

💡

If the image is too dark, increase the exposure setting to +1.0 or +1.5. But don't overdo it, with values higher. +2.0 will appear "broken" light areas (relights).

For street use, be sure to activate WDR (Wide dynamic range. This feature helps to preserve details in shadows and brightly lit areas, for example, if the camera is pointed at the front door, WDR prevents the "lighting" of a person's face against the background of the sun.

Setting up the motion detector and notifications

One of the key advantages CMSXJ11A — It's a built-in motion detector with a customizable zone of sensitivity, but by default, it can fire on everything from flying flies to wavering branches outside the window to reduce the number of false positives:

2. Activate Sensitivity and move the slider to 50-70% (better off 40%).
3. Click Setting up zones and highlight only those areas where you want to track movement (such as a door or gate).
4. In the Schedule section, set activity hours (for example, from 20:00 to 08:00 if the camera is watching the house at night).

To reduce cloud load and save traffic:

• 📤 Turn off Cloud Download (if you use microSD).
• 🔔 Enable Smart Notifications – The camera will only send alerts when a person is detected (not any movement).
• 🕒 Set 30 seconds delay between notifications to avoid spam.

⚠️ Warning: If the camera is outdoors, avoid pointing the lens directly at heat sources (such as air conditioning or battery).The motion detector responds to changes in infrared radiation, and such objects will cause false positives.

For advanced users: if the standard motion detector does not suit you, you can connect the camera to the Home Assistant through the Internet. RTSP-stream and customize your own automation rules, and this is covered in the section "Integration with third-party systems".

To open the hidden settings:

1. In the Mi Home app, go to the camera settings.
2. Quickly click on the firmware version line several times (5-7 Once, until the Debug Mode menu appears.

To improve night photography:

• 🌃 Install an additional IR spotlight (if the built-in illumination is not enough).
• 🔦 In the camera settings, turn on the IR filter: Auto and set IR Sensitivity: High.
• 📹 Reduce bitrate to 1024 Kbps – this will reduce noise in dark areas.

If the camera is installed in the open air, avoid pointing the lens in the sun - this can cause the matrix to overheat and artifacts in the image. 10-15 degrees) so that there is no sky in the frame.
