Designed with more lens than the conventional PTZ camera, the X-Spans series camera captures an expansive view, producing wide, vivid images. It has the combined power of the panoramic and detail camera in its structure and is highly cost-effective, greatly reducing the installation cost of security systems. It also leverages its two cameras to perform smart tracking, and has an independent mode that allows you to separately use each camera.
Features
- Starlight Technology - For challenging low-light conditions, Dahua's Starlight Ultra-low Light Technology offers the best in light sensitivity, capturing colour in vivid detail, even in lighting as low as 0.005 lux. The camera uses a set of optical features to balance light throughout the scene, producing clear images in dark environments.
- Smart H.265+ & Smart H.264+ - With advanced scene-adaptive rate control algorithm, Dahua smart encoding technology realizes the higher encoding efficiency than H.265 and H.264, provides high-quality video, and reduces the cost of storage and transmission.
- Perimeter Protection - Automatically filters out false alarms caused by animals, rustling leaves, bright lights, and more, and uses secondary recognition during target detection to improve alarm accuracy.
- Protection (IP66, TVS 6000 V) - IP66, TVS 6000 V lightning proof, surge protection, and voltage transient protection.
- Smart Dual Light - Dahua Smart Dual Light technology adopts smart algorithm to detect targets. Usually, the IR illuminator is on at night; when the target appears in the monitoring area, the white light is on, and the camera records the full-colour video and information of key events. That is, the camera links snapshot and video with full-colour image. When the target is out of the monitoring area, the white light is off and the IR illuminator is on, which reduces light pollution efficiently.

Fantastic upgrade from my original stand. Base is a little bulky, but stand is versatile and sturdy.
Size: Single, Style: Free-Standing, Size: Single, Style: Free-Standing
Amazing value for this stand. I needed a stand with more degrees of freedom than the original one that came with my monitor, and this stand (which was inexpensive relative to the cost of the monitor) was a great purchase. The base of the stand is a little bulky/high, and the soft material on the bottom of it can rub off very easily if you let the stand catch the back edge of your desk. Otherwise though, the stand is extremely easy to install, and it provides far more degrees of freedom for rotation and translation than the original stand for my monitor. Now my monitor is sitting at a comfortable viewing angle closer to my desk tilted slightly upwards toward me.
Just keep in mind that you have to tighten down the height and tilt adjustments (the things that would be affected by gravity). So, if you want to adjust those frequently, this stand might not be a great fit for you. That said, it does provide a hidden but easy-to-access spot to store the keys needed to loosen it up to make those adjustments. So, if you need to make those adjustments, you'll always have quick access to the necessary tools.
Highly recommended for its price in particular.

A Solid Monitor Stand
Size: Single, Style: Free-Standing
This is an extremely sturdy monitor stand. Easily assembled in less than 20 minutes. Instructions were simple. The hex tools came with the stand, but you just need a Nr 2 Phillips Screwdriver for the bolts mounting the VESA plate to the monitor. Take note that this stand has a heavy base to hold larger/heavier monitors up to 22 lbs, but does not take a lot of space. I chose this variant so that it could handle my heavy 24-inch Planar monitor. The included cable management clip was a nice touch. Rotation and tilt feature moves easily and has decent range. I'm very happy with my purchase and it was available for overnight shipment in my region.

WALI Dual Monitor Stand: A Solid, Space-Saving Base Camp
Size: Dual, Style: Free-Standing
WALI Dual Monitor Stand: A Solid, Space-Saving Base Camp
I needed to reclaim some real estate on my crowded desk, and this WALI freestanding mount did the trick. It's a straightforward, no-frills solution that holds my two 24-inch monitors securely and opens up a ton of space underneath.
Assembly is intuitive, though having a second pair of hands is helpful when you're attaching the monitors to avoid any tipping. The all-metal construction feels sturdy and reliable. The adjustments are basic but effective—you can raise or lower both monitors together on the central pole and tilt or swivel them individually to get the angles just right. The included cable management clips are a nice touch for keeping things tidy.
The key thing to understand with any freestanding mount is balance. If you extend the arms all the way out toward you, the whole unit can get top-heavy and want to tip forward. I keep my monitors positioned more centered over the heavy base, and it's perfectly stable. It's not meant for dramatic, extended poses.
For the price, it's fantastic value. It doesn't have the infinite, fluid adjustability of high-end gas-spring arms, but it doesn't need to. It lifts your monitors, frees up your desk, and does its job without any fuss.
Bottom Line: An excellent, budget-friendly way to lift two monitors and dramatically increase your usable desk space. Just be mindful of the center of gravity and don't expect ultra-flexible, independent positioning.

Easily supports a pair of 26" displays
Size: Dual, Style: Free-Standing
I have no complaints with this stand. It is not as nice as the Inland brand sold at MicroCenter, but it does its job. It beats the price of the MicroCenter one, thats for sure.
It comes with all the hardware you might need, even long screws and bushings if you have a display that needs them.
Assembly was quick. It comes mostly assembled anyway. You have to put the bottom on the post then attach the assembled arms to the post.
Setting up can be a challenge but with help, its easy. After mounting the bracket on the back of the displays, you just slide them into the receiver on the arms.
Once mounted, adjusting the position is simple, but can take a while as there are several joints which can be positioned to angle the displays as you like.
The cord clips do an OK job of cord management, but the clips are not as good as the Inland ones. They do the job, but not as durable. I broke the one that goes on the post, but I tried getting it to hold a wad of wire. My fault.
I recommend this stand.
