Attempting to connect more than eight Logitec cameras to a single computer.
Attempting to connect more than eight Logitec cameras to a single computer.
Hello everyone, I’ve reviewed numerous discussions and found only one addressing this matter in 2013. Beyond that thread, there aren’t many conversations about it anymore. I also shared my thoughts in that earlier thread, but I tried to bring the discussion back by reaching out to other forums.
My goal is to eventually record and broadcast video from my workshop space using eight Logitec C920x cameras, with some basic editing. After purchasing three, I encountered bandwidth challenges when attempting to run them through Obsidian on my MacBook Air M2, using only active cables and a powered USB hub. People in the earlier thread had discovered similar limitations due to insufficient bandwidth. I managed to get two cameras and my webcam working, but not three at once.
I delved into some articles about using multiple USB controllers, which seemed to work for others, suggesting that the problem might stem from the motherboard or CPU’s capacity to handle so many devices. (Perhaps due to a lack of understanding.)
I consulted micro center for advice and, in 2024, still faced confusion—my IT contacts, including myself, were still struggling. My only confirmation came from YouTube videos I found on the subject.
Micro center suggested purchasing these cameras to achieve the desired setup, though they were only 90% confident it would work. I appreciate their honesty.
Regarding components:
Motherboard
RAM
CPU
CPU cooler/fan
USB controller
Power supply
Case
A friend suggested a specific graphics card, but we’re unsure if it’s necessary for just streaming and recording, plus minor post-editing. They also mentioned the case micro center recommended was average and pointed to another option.
For my setup, I believe I could power several cameras—potentially up to eight, given the motherboard’s ports (four on the board, four on the controller, and possible hubs for more connections). This would allow me to keep cameras stationary while still having some mobility, especially if bandwidth remains sufficient. For my current needs, it might be practical to set up cameras that stay in place and only move occasionally.
I’d love to hear from anyone who has updated on this idea, as it could save costs compared to a full network camera system. I think it’s worth trying, since others seem confident about it, and I plan to share results once it works.
Thanks for your support,

The task you have in mind is quite challenging because it involves a specialized area of PC usage. This explains why few people are aware of it and why it's difficult to obtain relevant information about it.
In short, what you aim to achieve is a security network where all cameras link to one central PC. I recommend reaching out to some security companies that also install home security cameras. Ask them how they configure multiple cameras to connect into a single system. If your goal is to stream or broadcast live, the setup remains similar, even if your intention is different from just monitoring a specific area.
From a hardware perspective, consider using capture cards. Connecting all 8 cameras directly to the PC would strain the CPU's processing power, as it would need to handle all live feeds simultaneously. A capture card offloads rendering tasks to the CPU, providing higher quality and reducing the load on your processor.

Regarding PC configuration, it depends on whether you plan to do post-processing or video editing. If you also perform these tasks on the PC or use capture card feeds for direct uploads, a less powerful system may suffice. However, for video editing, you'll need ample RAM and possibly a strong GPU, especially if rendering is done primarily on the GPU.
The power supply you mentioned seems inadequate. It's advisable to choose a better one such as Seasonic Focus, Vertex, PRIME, Corsair RMx/RMi/HXi/AXi, or Super Flower Leadex series.
Before purchasing a PC, consult a security firm for guidance in selecting the appropriate hardware, as they have expertise in setting up multiple camera systems.
Thank you for the update, it seems we haven't had any success yet. Just hearing that these are outdated systems and they're no longer in use. Some messages were left by sales teams as well, so fingers crossed we'll get a reply soon.
In general, each shopping mall or large commercial building operates its own security camera system, with all devices linked together and their live streams directed to a security room where officers watch them. The recordings are also kept, which is required by law in many regions. In terms of requirements, there isn’t much change from this setup. Technically, the hardware remains consistent. What matters is identifying a company that can assist with installation.
You don’t need to disclose the intended use of the camera network, as it’s not their concern. All you require is expertise in configuring it.
Note: The Cooler Master Q300L PC case offers more flexibility than the Lian-Li model. Unless you prefer a unique setup, the Lian-Li case is unnecessary unless it significantly reduces cost.
For example, the Q300L features a modular I/O panel allowing up to six different configurations, and it supports side placement of the PC. The Lian-Li case, by contrast, is designed to stand upright and lacks this adaptability.

Depending on your choice of system, you might need a full-sized ATX case with ample USB ports, or you could opt for internal capture cards or external devices.
I strongly suggest using IP-based cameras instead of USB ones. IP cameras can be powered by a POE ethernet switch and remain up to 100 meters away. There are no cabling problems with powered hubs, etc. IP cameras include built-in compression hardware, enabling multiple cameras to connect to one host. Eight 1080P or a combination of 1080P and 4K IP cameras works perfectly. USB cameras likely don't compress data over the USB link—they rely on the host for compression and formatting.
Thank you for your feedback. This sounds like a solid approach with a full-size motherboard, ample USB ports, and internal capture cards for future expansion. If needed, adding more components is definitely possible. Regarding the cooler master, its side-lying design is a nice feature, especially since space is limited.
I'd prefer using the USB option since I already have one available, and I'm aiming to skip the expensive setup process. I understand USB can be a bit of a hassle, but I'm determined to make it work until the end.
From a software perspective, iSPY is well-suited for linking various USB webcams to a single PC. The provided link leads to information about the platform and its capabilities. It supports connecting multiple cameras, recording streams, capturing screenshots at intervals, and integrating motion detection features. The download option defaults to Agent DVR, but you can also choose iSPY from the menu. While Agent DVR shares similarities with iSPY, it operates online and uses less CPU power, allowing remote access via a browser. iSPY itself functions as a standalone application on your PC. A helpful guide is available for optimizing performance and reducing strain on the system, especially when dealing with high-resolution cameras at full frame rates such as 1080p or 60 FPS.
