Xiaomi’s modern surveillance cameras and the Mijia ecosystem are known for their minimalist design and thoughtful design, which often baffles users who want to do self-repair. Unlike older analog systems, there are virtually no visible screws, and all mounts are hidden under decorative elements or rubber plugs. Disassembling such devices requires patience, understanding the principles of plastic latches and the presence of a specialized tool to avoid damaging the fragile body and internal plumes.
Before starting dismantling, you need to be clear about the risks: broken seals or careless handling of electronics can lead to loss of warranty and failure of the device. Most often, the need to disassemble the camera arises when you jam the rotary mechanism, get moisture inside the case or want to replace the memory card if the slot is deep. The internal layout of these devices is extremely dense, so each movement must be adjusted.
In this article, we will consider in detail the stages of disassembly of popular models, pay attention to the nuances of opening the case and methods of safely disabling plumes. You will learn what tools are really necessary and what can harm, and also analyze the typical mistakes made when you first get acquainted with the design. IP-The right approach will extend the life of the device or successfully replace the failed module.
Tools and workplace preparation required
The quality disassembly of any electronics begins with the organization of the workspace and the selection of the right tool. Xiaomi cameras are characterized by the use of small diameter screws and plastic latches that are easy to break when using brute force. You will need a set of precision screwdrivers, including the cross PH0 and PH00, and a flat screwdriver for neat tweaking of the case.
Special attention should be paid to mediators or plastic blades, which are indispensable for working with clips. Metal tools such as knives or thick needles, it is better to put aside, as they are very easy to damage plastic guides or cut through the insulation of the plume. Also prepare a screw container, tweezers with curved ends and, preferably, a magnifying glass or macro shooting on the phone to fix the order of unscrewing the bolts.
⚠️ Warning: Before starting any work, be sure to disconnect the camera from the power supply. Even a low voltage of 5 or 12 volts with careless tweezers can disable the motherboard or burn the fuse.
An antistatic bracelet may be required to handle electronic components inside the chamber, although household repairs often require simply touching a grounded metal object before manipulation. Static electricity is an invisible enemy of chips that may not appear immediately, but after assembly.
☑️ Preparation for disassembly
Specific design and types of anchorages
Xiaomi engineers use several types of mounts depending on the camera model, whether it is a stationary Mijia Camera or a rotary Pan-Tilt version. The main element of fixation is hidden screws, which are often hidden under serial number stickers, rubber legs or decorative rings around the lens. It is not always possible to find them the first time, so you need to carefully inspect the case from all sides in good light.
The second type of mounts are plastic latches that hold the halves of the body together. They are located around the perimeter of the device and require careful clicking around. A sharp jerking motion at one point is almost guaranteed to break the plastic or chip on a glossy surface. Clips in Xiaomi devices are often made of rather rigid plastic, which becomes brittle in the cold, so it is recommended to work at room temperature.
A third, less common, but common type is propellers with custom hats, such as Torx or triangles, which indicate that the device is not designed for user service and the manufacturer prevents it from opening, in which case a special bat or a neat drilling of the cap may be required if the original tool is not available.
It's important to understand that design can change even within a single line of devices. If you're taking a camera apart for the first time, it makes sense to find a video disassembly of your model or the most similar one. Visually identifying the hidden mount elements will save you time and nerves during the dismantling process.
Step-by-step instructions for disassembling the body
The opening process should begin by finding and removing all visible screws. Often, one or two screws may be under a removable bottom lid or under a rubber plug at the bracket mount. After unscrewing all the bolts, don't immediately try to separate the halves of the body - most likely they are held by the latches. Take a plastic blade or mediator and start walking along the junction of the halves, carefully snapping the clips.
Move around the perimeter, gradually increasing the gap between the parts of the body. Don't stick the tool deep, 2-3 millimeters are enough to hook the latch and turn the blade. A characteristic click will tell you that the lock is free. If the case does not diverge, do not use force - check if you missed another screw, perhaps it is hidden under a sticker that will have to be partially unsticked or carefully cut.
⚠️ Warning: It is strictly forbidden to use force when trying to open the case unless you are sure that all the screws are twisted. Excessive pressure will break the plastic ears, and you will not be able to put the device back together tightly.
Once all the latches around the perimeter are free, you can carefully remove the upper or front of the body. In Pan-Tilt models, often the dome or front panel is removed first, and then access to the main board is opened. Act slowly, controlling the force so that the thin walls of the plastic are not damaged.
What to do if the plastic cracks?
Working with internal components and plumes
When you open the case, you'll see the main board, the lens module, the speaker and the microphone, all connected by plumes, and the plumes are the most vulnerable parts of the structure. ZIF-connectors (with a pinned bar) or simply inserted into the connector. Before disconnecting any plume, carefully examine the connector: if there is a black or white bar, it should be carefully lifted with tweezers or nails, after which the plume will easily exit.
In Xiaomi's rotary cameras, pay special attention to the plume going to the movable part with the lens. It is often laid through the hinge and can be pulled. If you sloppyly open the case, there is a risk of tearing this plume, which will lead to loss of video signal or inability to control the turn. Connectors on the board can be very small, so use tweezers with thin noses, but act carefully so as not to damage the neighboring elements.
If the purpose of disassembly is to clean the lens of dust or webs, try not to touch the lens and matrix with your fingers. Fat marks are extremely difficult to remove without special wipes and liquids. Use a purge pear or a can of compressed air, holding it vertically so that liquid does not fly out.
| Component | Function | Risks in disassembly | Service board |
|---|---|---|---|
| Lens module | Image formation | Dust hitting the matrix, focus knocking | Clean only with a pear, do not touch your fingers |
| Turning mechanism plume | Data and power transmission | Breaking of current tracks | Don't pull, check the fixation |
| Dynamician and microphone | Audio communications | Membrane damage, contact separation | Blow carefully, without strong pressure |
| Wi-Fi antenna board | Receiving the signal | Breaking the antenna wire from the board | Don't pull the wire, take the connector. |
When you build back, make sure that all the plumes are plugged in and locked. An unpressed connector is a common reason that the camera, after assembly, stops seeing the memory card or loses communication with the server.
Nuances of disassembly of rotary mechanisms (Pan-Tilt)
Pan-Tilt cameras have more complex mechanics than static ones, and it's important not only to open the body, but also to properly dismantle the movable head with the lens, often mounted on magnets or hidden latches that you need to find by sampling. When removing the movable part, you may need to unscrew several screws that are only accessible when the outer ring is removed.
Inside the gears, there are gears that can wear out or become contaminated with old lubricant over time, causing a characteristic crackle or jamming. Mechanical wear is one of the main reasons you're using the service. If you get to the gears, you better remove the old lubricant with alcohol and apply a new, silicone, designed for plastic gears.
💡
When assembling the rotary mechanism, make sure that the plume is laid in a special groove or fixed, otherwise, when the camera is rotated, it will rub against the body.
It is also worth checking the status of the contact sites if the signal is transmitted through connectors, not flexible plumes. oxidation of the contacts can cause the signal to disappear when you turn the camera in a certain direction. Use a regular eraser or cotton swab dipped in alcohol to clean.
⚠️ Attention: When disassembling the mechanical part, do not make any effort to the engine itself. The motor editors are very sensitive to lateral loads and can break if you try to turn them manually with effort.
Assembly of the device and check of performance
Xiaomi camera assembly is done in reverse order, but requires even more care than disassembly. Make sure all screws are twisted evenly, without distortions that can create tension in the plastic. The plumes should lie flat, without clamps or tension. Before you finally snap the case, it is recommended to connect the camera to the power and check its operation in the open.
Check the camera image, the IR lighting (closing the light sensor with your finger), the response to the rotation commands and the sound quality. If everything is working correctly, you can carefully assemble the body, starting on one side and gradually closing the latches around the perimeter. A characteristic click around the circuit will confirm the correct assembly.
If the camera doesn't turn on or doesn't behave properly after assembly, don't rush to disassemble it again immediately. Try restarting the device by turning off the power for 10-15 seconds. Often electronics need to reset after manipulating the internal components. Diagnostics on an open table is a key step to avoiding re-disassembly.
💡
The main check before the final assembly is to make sure that the camera sees the Wi-Fi network and broadcasts the image, as after closing the case, access to the indicators will be limited.
If you have changed your memory card or reset your settings, remember to re-attach your device in the Mi Home app. Sometimes, after opening and turning off the power, the camera may be perceived by the system as a new device or require re-authorization.
