Disassembly and repair of the Xiaomi Mijia 1080p camera with your own hands

Popular IP-Xiaomi Mijia series cameras 1080p They have proven themselves as reliable devices for home video surveillance, but over time, even high-quality electronics fail. Most often, users are faced with mechanical damage to the pivot mechanism plume, contamination of the lens from the inside or breakage of the IR illumination, which requires immediate intervention. Disassembly of the device seems difficult due to the lack of visible screws, but with the right tools and knowledge, this process becomes quite feasible at home.

Before you start dismantling, it is necessary to clearly understand that opening the case will automatically void the manufacturer's warranty obligations. If your device is still in warranty service, it is wise to contact an authorized service center, since self-repair carries the risks of final failure. However, if the camera is no longer warranty repairable or you are confident in your abilities, this smart guide will help you safely disassemble the camera to replace components.

In this article, we will take a detailed look at the dismantling stages of popular Xiaomi Mijia 360° 1080p models (including the CN and Global versions), paying special attention to fragile plastic latches and thin plumes. You will learn what tools will be required to work, how to turn off the battery and not damage the optics when removing the protective dome.

Tools and workplace preparation required

To successfully disassemble the Xiaomi Mijia, you will need a minimum set of specialized tools, as standard screwdrivers may not fit with hidden head screws. The main tool will be a plastic blade or mediator that will allow you to gently snap the clips of the case without the risk of leaving scratches or chips on glossy plastic. Metal tools such as knives or sewers are not recommended, as they can easily damage internal components or puncture the battery.

Special attention should be paid to the organization of the workspace: the table should be well lit, and all the small parts should be folded into a magnetic tray or numbered containers. The screws in Xiaomi cameras can have different lengths and threads, so confusing them when Assembly means risking to tear the thread in the plastic racks. It is also strongly recommended to use an antistatic bracelet or periodically touch a grounded metal object, so that static electricity does not disable sensitive electronics.

Below is a list of tools that are guaranteed to be needed in the process:

• 🛠️ Precision screwdriver kit (cross-hatch) PH0, PH00 and slit-faced)
• 🔧 Plastic blades for opening the body (spudger)
• 🧲 Magnetic holder for screws or organizer with cells
• 💡 Additional lamp for illumination of internal components

⚠️ Warning: Before starting any work, be sure to disconnect the camera from the 220V power supply. Working with electrically energized electronics is prohibited and can lead to short circuit or electric shock.

Preparing the workspace is the foundation of successful repairs, and neglecting this stage often leads to the loss of fine parts. Make sure you have enough space to accommodate the removed parts of the case and plumes that can not be bent at a sharp angle. If you first encounter disassembly of such equipment, the process can take from 30 to 60 minutes, so the rush here is irrelevant.

Removal of the protective dome and upper ring

The first step in dismantling the Xiaomi Mijia 1080p is to dismantle the upper transparent dome, which protects the rotary mechanism from dust. In most models, this element is supported by a tight landing and several hidden locks, so you can not make excessive effort. Start by carefully probing the junction between the dome and the main body to find technological gaps where you can insert a plastic blade.

Some camera modifications have a decorative ring that must be removed first, poking it up in the area of the MI logo. Movements should be progressive and smooth, without jerking, as the plastic in the cold or at low temperatures becomes more brittle and brittle. If the dome does not lend itself, try to slightly warm the perimeter of the joint with a hairdryer at a minimum temperature to soften the adhesive layer or make the plastic more elastic.

It's important to remember the internal optics: when you remove the dome, you risk hitting the lens with your fingers or tool, leaving fat spots that will impair the image quality. The purity of the optics is a key factor for night photography, so try not to touch glass surfaces unnecessarily. Once the dome is removed, you will have access to the rotary module and the main control board.

The process of removing the upper ring requires care, as it often hides the screws holding the main structure. If you feel resistance, double-check for hidden screws under stickers or rubber plugs that may have been missed in the previous step.

Dismantling the main building and access to the board

After removing the external protection elements, the turn of the main body, which consists of two or three parts connected by screws and plastic latches, turns the camera upside down and carefully examine the lower part: there may be screws hidden under a rubber anti-slip lining or a sticker with a serial number. Carefully remove these obstacles using tweezers or a thin blade to avoid damaging the marking.

To unscrew the screws, use a screwdriver of the appropriate size, pressing it tightly against the screw head so as not to tear the slats. The screws in Xiaomi Mijia are often of different lengths, so immediately sort them into groups depending on the place of twisting. After removing all the screws, you need to use the plastic blade again and walk along the perimeter of the junction of the halves of the body, sequentially snapping the internal locks.

Inside, you'll see the main board, the speaker and the rotation module, connected by plumes of varying thicknesses. The plumes are the most vulnerable parts of the structure, and damage to them when disassembled is the most common cause of failure. Before you completely disconnect the halves of the case, make sure that all connectors are free or ready to shut down.

• 🔍 Visually inspect the charge for swollen capacitors or traces of corrosion
• 🔌 Check the density of the plume connectors before they are turned off.
• 🧹 Remove visible dust with compressed air or a soft brush

⚠️ Warning: Plastic latches of the case can be very tight. Don't try to separate the case by force if the screws are twisted - look for hidden locks, otherwise you will break the mounts.

The opening of the case is the point of no return, after which the device is considered to be opened. At this stage, it is important to remain calm and methodical, checking each action. If the case does not open, carefully examine the structure for forgotten screws or hidden clips.

Shutting down the battery and plumes

The first step after opening the Xiaomi Mijia case is to disconnect the battery from the motherboard.This is a critical safety step that prevents short circuits when working with electronics and protects components from surges. The battery is usually connected through a two- or three-wire connector that is located on or below the edge of the board.

To turn off the plumes going to the pivot module and the lens, you need to bend the connector's locking tongue (if any) and carefully pull the plume itself, not the wires. Connectors in modern cameras are very miniature and fragile, so using tweezers should be extremely careful not to damage the contact areas on the board. If the plume sticks to the board, you can slightly spool it with a plastic blade at the base of the connector.

The table below shows the main types of connections you will encounter inside the camera:

Once all communications are turned off, the camera's main module becomes fully autonomous from the base, allowing for the safe extraction of the board for further diagnostics or replacement of components. Remember that some models may have additional wires going to the speaker or microphone, which also need to be disconnected.

💡

Use plastic tweezers instead of metal tweezers when working with connectors to minimize the risk of accidentally closing contacts on the board.

Properly disabling the plumes ensures their integrity when assembled.If you plan to change the plume, make sure the new component is fully compatible with your board revision.

Disassembly of the rotary mechanism and replacement of the plume

The most common reason Xiaomi Mijia 1080p disassembly is to replace the swivel loop, which is rubbed during long-term operation. To access this unit, you need to remove a metal or plastic screen that covers the horizontal and vertical motors, and this screen is attached to several screws that need to be twisted out and folded neatly.

The plume itself passes through the rotation axis, and as the camera moves, it gradually wears out, causing the image or sound to disappear. To replace it, you need to unscrew the camera module from the vertical axis motor, carefully remove the old plume, and install a new one, observing the correct orientation of the contacts. The orientation of the plume is critical: improper installation can lead to short circuit and combustion of the motor controller.

When assembling a rotary mechanism, it is important to correctly place the plume in the intended groove so that it does not clamp or rub it when rotating. The excess plume should not dangle or protrude outside the body, otherwise they will interfere with rotation. After installing a new plume, it is recommended to manually check the smoothness of the mechanism before final assembly of the body.

• 🔄 Check the engine before installing protective screens
• 🧵 Make sure the plume is not stretched and has a small range
• 🔩 Twirl the screws of the engines with moderate effort, without tugging

⚠️ Warning: When replacing the pivoting mechanism plume, be sure to check the integrity of the tracks on the new component.Even a microscopic rupture can lead to unstable camera operation.

Replacing a plume is a hard handed operation that requires good vision, and if you're not sure about your soldering or microelectronic skills, you'd better leave it to the professionals, but if you're careful, replacing the plume completely restores the rotary mechanism to function.

💡

High-quality laying of the plume in the groove of the axis of rotation is the key to the long service of the camera after repair.

Device assembly and initial inspection

The Xiaomi Mijia is assembled in reverse disassembly order, but with extreme caution when installing the plumes and connecting the battery. First, connect the battery and check the camera reaction: the indicator should light up, and the motors can emit a characteristic calibration sound. If the camera shows signs of life, you can continue to build, otherwise you need to double-check all connections.

When installing the main module in the housing, make sure that all wires and plumes are in their channels and do not fall under screws or latches. Cable management inside the compact camera housing is very important: any unnecessary bending or clamping of the wire can lead to breakage during subsequent operation. Twirl the screws of the case evenly, without undue effort, so as not to damage the thread in the plastic.

The final step is to install a transparent dome and a decorative ring, make sure that the dome is flat and has no skews that can create glare on IR lights at night. Once fully assembled, connect the camera to the network and wait for it to load: the device should issue a voice greeting and begin the pairing procedure.

Successful camera assembly and launch means the repair is successful, and the device is now ready to be installed and set up through the Mi Home app.
