There’s a moment in every ambitious home security project that I like to call “the point of no return.” It’s not when you drill the first hole or mount the first camera; it’s when you look down at the floor beneath your NVR or monitor and see it. A chaotic nest of black power adapters, extension cords, and daisy-chained power strips, all competing for the last available socket. I’ve been there more times than I can count. Each camera comes with its own bulky plug, creating a setup that’s not only unsightly but also a significant point of failure. One accidental kick, one overloaded socket, and your eyes in the dark go blind. This disorganized approach is the enemy of reliability. Centralizing your power isn’t just an aesthetic upgrade; it’s a fundamental step towards creating a robust, professional-grade surveillance system that you can truly depend on when it matters most.
- Input voltage: AC100-120V / AC220-240V (110/220V switchable), Output voltage: DC 12V, 9 channel output. The total DC voltage can be adjusted by 10%.
- The maximum output is 10Amp and the total power is 120W. Up to 5 cameras with 2A maximum output can be connected. Maintain the device no more than 80% load power.
What to Consider Before Buying a CCTV Power Supply Box
A CCTV Power Supply Box is more than just an item; it’s a key solution for transforming a haphazard collection of cameras into a streamlined, manageable security network. Its primary benefit is consolidating power delivery, eliminating the need for multiple individual adapters. This simplifies installation, drastically reduces cable clutter, and provides a single point for troubleshooting. By delivering clean, regulated 12V DC power from a central unit, you ensure each camera receives a consistent and stable energy source, which can extend the life of the components and prevent performance issues like video flicker or IR cut filter failures. Furthermore, these boxes often include critical safety features, such as individual fuses for each channel, offering a layer of protection that a simple power strip could never match.
The ideal customer for this type of product is the dedicated DIY enthusiast or professional installer who is setting up a system with four or more cameras. If you’re running cables through walls and attics for a permanent, clean installation, the Weishuo 9-Channel CCTV Power Supply Box is designed precisely for your needs. It’s for the person who values reliability, serviceability, and a professional finish. However, it might not be suitable for those who need a simple plug-and-play solution for one or two cameras. If you’re not comfortable with basic electrical wiring (stripping wires and connecting them to screw terminals), a centralized PSU like this will be more of a challenge than a solution. For those users, sticking with the manufacturer-provided adapters or considering a multi-port USB power adapter (for compatible cameras) might be a better fit. It’s also critical to understand this is a Power Supply Unit (PSU), not an Uninterruptible Power Supply (UPS); it distributes power, but it does not provide battery backup during an outage.
Before investing, consider these crucial points in detail:
- Dimensions & Space: These units are metal boxes designed to be wall-mounted, often near your NVR or in a utility closet. The Weishuo 9-Channel CCTV Power Supply Box measures 25.2 x 21.8 x 5.9 cm. You must ensure you have adequate, secure wall space for mounting, with enough clearance to open the door and manage the incoming and outgoing wiring. Consider ventilation as well; while they don’t typically run hot, they shouldn’t be installed in a tightly enclosed, unventilated space.
- Capacity/Performance: This is arguably the most critical factor. The Weishuo box provides a total of 10 Amps (120W) across 9 channels. It’s crucial to check the power requirements (in amps or watts) of each of your cameras and add them up. For optimal performance and longevity, your total load should not exceed 80% of the unit’s maximum capacity, which is 8A in this case. Also, note the per-channel fuse limit, which is 2A on this model, more than enough for most standard CCTV cameras but something to be aware of for power-hungry PTZ (Pan-Tilt-Zoom) units.
- Materials & Durability: Look for a sturdy metal enclosure, not plastic. The Weishuo 9-Channel CCTV Power Supply Box features a lockable metal case, which we found to be robust and well-suited for protecting the internal components. This construction not only offers physical security but also helps with heat dissipation and provides a degree of fire resistance, which is a vital safety consideration for any device that runs 24/7.
- Ease of Use & Maintenance: “Ease of use” here is relative. It requires manual wiring of both the main AC input and the individual DC outputs. Once installed, however, maintenance is straightforward. The key feature we appreciate is the individual LED indicator for each channel. If a camera goes offline, a quick glance at the box can tell you if the issue is power-related (LED is off), saving you valuable diagnostic time. The inclusion of replaceable glass fuses also means that if one channel is shorted, it won’t take the entire system down.
Ultimately, a dedicated power supply box is a cornerstone of a serious security installation, offering benefits in organization, safety, and long-term reliability.
While the Weishuo 9-Channel CCTV Power Supply Box is an excellent choice for power distribution, it does not provide backup power in a blackout.

First Impressions: A Utilitarian Powerhouse
The Weishuo 9-Channel CCTV Power Supply Box arrives in a plain, unassuming cardboard box. There are no fancy graphics or marketing slogans here; this is a tool, not a consumer gadget. Inside, the unit is securely packed. Lifting it out, the first thing we noticed was its reassuring heft. At nearly 1.4 kg, the powder-coated metal enclosure feels substantial and durable. It’s not overly heavy, but it has a ruggedness that inspires confidence. The hinged door opens smoothly and closes with a satisfying click, secured by a simple lock—two keys are provided. Included in the box is a basic wall mounting kit (screws and wall plugs) and, thoughtfully, four spare glass fuses. One user review noted the inclusion of a power lead, but our test unit did not include one, which is standard for these types of professional PSUs. They require you to hardwire your own AC power source. The interior is cleanly laid out, with a main transformer, a circuit board with nine clearly labelled screw-down terminal blocks for your cameras, and corresponding status LEDs and fuses for each output. It’s a no-nonsense design focused squarely on function, ready to become the heart of a security system. You can see the straightforward internal layout in the product images.

Deep Dive: Performance Under Real-World Conditions
A power supply box might seem like a simple component, but its performance is the bedrock upon which your entire surveillance system’s reliability rests. We put the Weishuo 9-Channel CCTV Power Supply Box through a series of tests, connecting it to a mixed-brand setup of six cameras—four standard turrets and two more power-intensive motorised varifocal models—to simulate a typical real-world load and evaluate its core functionalities: installation, power delivery, and safety mechanisms.
Installation and Setup: A Task for the Confident DIYer
Let’s be perfectly clear: installing the Weishuo 9-Channel CCTV Power Supply Box is a hands-on task. Out of the box, you’re presented with a metal cabinet and a set of terminals. There is no AC power cord included, as the unit is designed to be hardwired. We mounted the box to a plywood board in our workshop using the provided screws. The process was straightforward, with keyhole slots on the back allowing for easy placement. Once secured, we opened the locked door to access the internal terminals.
The input power connection requires you to wire a mains cable to the L (Live), N (Neutral), and Ground screw terminals. This is the most critical part of the installation and should only be undertaken if you are knowledgeable about safe electrical practices. Before making any connections, we used the small switch on the side of the main power block to select the correct input voltage (220V for our UK testing). This is a crucial step to avoid damaging the unit. Connecting the cameras was much simpler. We ran our 12V DC power cables from each camera location to the box. Each of the nine outputs features a pair of screw terminals (+ and -). We stripped a small section of the wire, inserted it into the correct terminal, and tightened the screw. The terminals provided a secure grip on the wires. Once everything was connected, we powered on the unit. The main power LED illuminated, as did the individual green LEDs for each of the six connected channels, providing immediate visual confirmation that every camera was receiving power. The entire process, excluding running the camera cables themselves, took about 20 minutes. It’s not complex, but it demands care and a basic understanding of wiring. For those ready to move beyond messy adapters, this organised approach is a game-changer.
Power Delivery and Load Management
The headline figures for the Weishuo 9-Channel CCTV Power Supply Box are 12V, 10A, and 120W. In our testing, the core function of delivering stable power was flawless. With a multimeter, we measured the output voltage at the terminals with no load, and it registered a steady 12.15V. A very useful feature is the small potentiometer (labelled “ADJ”) next to the main terminal block. This allows for fine-tuning the output voltage. We were able to adjust it from approximately 10.8V to 13.2V. This is an excellent professional feature, often used to compensate for voltage drop on very long cable runs, ensuring a camera 50 metres away receives the full required voltage.
With our six cameras connected (a combined theoretical load of around 3.5A), the voltage remained stable, and the unit ran cool to the touch. The 80% load recommendation (8A) is wise counsel. This leaves plenty of headroom for power spikes, such as when all cameras switch their infrared LEDs on at dusk simultaneously. With a capacity of 10A, this unit can comfortably power a full 8-camera NVR system, even with a few power-hungry models, and still have a spare channel. We simulated a short circuit on one channel by deliberately touching the positive and negative wires. Instantly, the LED for that channel went out, and the camera lost power, while the other five cameras remained completely unaffected. After removing the short, we opened the box and found the channel’s glass fuse had blown as designed. Replacing it with one of the included spares took seconds, and the channel was operational again. This individual protection is precisely why a dedicated PSU is superior to a simple power splitter cable, as it isolates faults effectively. The individual fusing and status LEDs are its standout reliability features.
Safety, Build Quality, and Long-Term Reliability
The overall build quality of the Weishuo 9-Channel CCTV Power Supply Box is solid. The metal enclosure is well-finished, with no sharp edges, and the door lock, while simple, is effective at preventing casual access. Inside, the circuit board is neatly soldered, and the wiring is tidy. The unit’s proclaimed protections against short circuits, overloads, and overvoltage are essential for a 24/7 operational device.
However, we must address the most concerning user report we found, which described a catastrophic failure where the unit blew not only its own fuse but also the MCB and RCD in the consumer unit, causing damage to internal resistors. This is a serious event. While our test unit performed perfectly and we could not replicate this failure, such a report cannot be ignored. It points to a potential for significant quality control variance between batches or, in the worst case, a design flaw under specific fault conditions. It could also have been caused by an installation error, but the outcome is alarming regardless. This stands in stark contrast to another user’s experience of using it for a custom elevator control project without issue. Our assessment is that while the design is sound and our unit was reliable, there is a non-zero risk of receiving a faulty unit. We strongly recommend testing the unit thoroughly upon installation and, if possible, powering it through a surge protector for an added layer of safety. The peace of mind from a clean, professional installation is immense, but it’s important to be aware of the potential risks highlighted by user feedback.
What Other Users Are Saying
Synthesizing feedback from other users provides a valuable, multi-faceted view of the Weishuo 9-Channel CCTV Power Supply Box. The experiences are notably polarized, highlighting a divide between flawless operation and critical failure. On one hand, a French user reported using it successfully for a custom project (“alimenter divers composants de commande ascenseur fait maison”), waiting to evaluate it before confirming that they encountered no problems. This suggests that when the unit works, it works reliably for its intended purpose.
On the other end of the spectrum is the deeply concerning report from a user whose unit “Blew the mains fuse in the PSU, the MCB and the RCD,” causing “Significant damage to some of the resistors.” This is the worst-case scenario for any electrical component and underscores a potential quality control issue. Another review reveals common confusion about the product’s category, referring to it as a “battery backup” and noting that “you do have to supply your own battery.” This is incorrect; the Weishuo is a PSU only and has no battery backup or charging capabilities, highlighting the need for buyers to understand exactly what they are purchasing.
