If you’ve ever worked on a project involving embedded vision, industrial inspection, robotics, or even smart home devices, you’ve likely used board level cameras. As a supplier who’s spent the last 12 years designing, testing, and shipping these compact vision modules to clients across automotive, medical, and consumer tech sectors, I’ve seen just how transformative these tiny, integrated cameras can be—but I’ve also seen their limitations hold even the most well-planned projects back. Board Level Cameras
I get it: board level cameras are the backbone of modern vision systems. They’re small enough to tuck into tight spaces on a circuit board, pre-integrated with sensors and signal processing, and way more cost-effective than building a custom camera from scratch. For small startups and large manufacturing lines alike, they’re a no-brainer for quickly adding computer vision, image capture, or depth sensing to a product. But for all their advantages, they’re not a one-size-fits-all solution. Relying on them without understanding their boundaries leads to delayed timelines, unexpected costs, and underperforming end products.
Let’s start with the most obvious limitation: physical and optical constraints that can’t be easily modified after integration. Unlike enclosure-style cameras, which are built with adjustable lenses, weather-sealed housings, and mounts that can be repositioned, board level cameras are designed to sit flush on a PCB. Their lens is fixed to the module, so you’re stuck with whatever field of view, focal length, and light-gathering capability the manufacturer built in. I had a client last year who was developing a medical device for tracking hand movements during physical therapy. They ordered a standard 2MP board level camera with a wide-angle lens to capture a full view of a patient’s hand and arm, only to realize mid-prototype that the wide angle introduced too much distortion at the edges of the frame. Because the lens is glued directly to the sensor on the board level module, they couldn’t swap it out without reworking the entire PCB layout—something that set their launch back three months and added $120,000 in unplanned engineering costs. That’s the kind of avoidable misstep that comes from overlooking the fixed optics of these modules.
Alongside fixed optics, most off-the-shelf board level cameras have limited sensor performance when pushed to edge cases. Let’s talk about low-light performance first. A lot of standard board level cameras are built for bright, controlled environments—think a factory floor with overhead LED lighting or a living room with standard ceiling bulbs. But when you need to use them in dim settings, like a security camera for a dimly lit hallway or a night-vision module for a delivery drone, their small sensor size works against them. The sensor’s light-gathering area is tiny, so it struggles to capture enough photons in low light, leading to grainy, noisy images that make it impossible to accurately identify small objects or read text. A client in the industrial inspection space told me they tried using our standard 5MP board level camera for inspecting small printed circuit board components in a low-light cleanroom, and the noise in the images made their inspection algorithm fail 15% of the time. We suggested a higher-light variant, but even that couldn’t match the performance of a custom sensor with a larger area for their specific use case.
Then there’s dynamic range. Dynamic range refers to a camera’s ability to capture detail in both very bright and very dark areas of the same image. For example, if you’re building a camera for a car’s driver-assistance system (ADAS), you need to see both the bright sun glare on the road ahead and the dark shadows under a tree at the same time. Most entry-level and mid-range board level cameras have a dynamic range of around 60 to 80 decibels (dB), which is fine for basic tasks like face recognition in a well-lit office, but woefully insufficient for outdoor or high-contrast environments like ADAS, agricultural crop monitoring, or even kitchen appliances that need to see a hot oven rack next to a dark countertop. We had a automotive client come to us after their initial prototype failed during testing at a trade show, where the camera couldn’t distinguish a pedestrian in shadow next to a bright street sign. Their board level camera’s dynamic range was too low, so the pedestrian’s silhouette was completely lost in the dark, and the bright sign washed out all detail. That’s a safety-critical failure that could have been avoided if they’d assessed the dynamic range needs for their specific environment instead of just choosing a cheap, off-the-shelf module.
Next, processing limitations. Board level cameras are designed to be plug-and-play, which means they often include on-board processing for basic tasks like image compression or white balance. But if you need custom processing—like running a proprietary computer vision algorithm for quality inspection, or real-time depth mapping for a robotic arm—most standard modules can’t handle it. The on-board processor is designed for general use, not for heavy, custom workloads. I’ve worked with several robotics startups that tried to use board level cameras for their robotic pick-and-place systems, only to find that the camera’s on-board processing added 200 milliseconds of latency to each image frame. That’s enough lag to make the robotic arm miss its target, especially when moving at high speeds. They ended up ditching the board level camera entirely and using a camera module with an external processor to run their custom algorithms, because the board level’s pre-installed processing couldn’t be modified. Even if you can modify the firmware, most manufacturers lock down the processing capabilities to prevent tampering, so you’re stuck with whatever basic functions the module was built for.
Then there’s environmental resilience. Board level cameras are often not designed for harsh operating conditions, unless you specify an industrial or automotive-grade variant. Consumer-grade modules, which are the cheapest and most common, can only operate in temperatures between 0°C and 40°C, and have no protection against dust, moisture, or vibration. That’s fine for a smart doorbell that sits indoors or in a sheltered porch, but terrible for applications like outdoor security cameras, construction site monitoring, or agricultural sensors that are exposed to rain, extreme temperatures, and heavy vibration from machinery. A client in the agriculture space tried using a consumer-grade board level camera for a crop monitoring system mounted on a drone, and after two weeks of flying in dusty, humid conditions, the camera’s lens fogged up and the sensor got damaged from vibration. They had to replace 80% of their modules before their field testing was even complete, adding $50,000 in unexpected costs. Industrial-grade board level cameras are more resilient, but they come at a 30 to 50% price premium, which eats into the cost savings that make board level cameras attractive in the first place.
Wait, let’s not forget about connectivity and compatibility. Most board level cameras use standard interfaces like USB, MIPI, or I2C, but that doesn’t mean they’re compatible with every system. For example, if you’re building a product with a low-power microcontroller, a board level camera that requires high-bandwidth MIPI might not work, because it would drain the microcontroller’s battery too quickly. Or, if you’re working with an older system that only supports USB 2.0, a board level camera that only has USB 3.0 connectivity won’t work with your hardware. I had a client in the wearable tech space who was building a smart fitness tracker with a built-in heart rate camera. They ordered a board level camera with a high-speed MIPI interface, only to realize that their tracker’s tiny microcontroller didn’t have a MIPI port. Adapting the camera to their hardware required an extra interface board, which added size and cost to the final product—something they hadn’t considered when they chose the off-the-shelf module. Even when the interface matches, some board level cameras come with proprietary software drivers that only work on Windows or Linux, not on real-time operating systems (RTOS) used in industrial or automotive applications. That means you can’t integrate the camera with your custom software, forcing you to either rewrite your entire system or switch to a different camera.
Now, I’m not here to say board level cameras are bad—far from it. They’ve revolutionized how quickly companies can bring vision-based products to market, and they’re an essential component for millions of devices today. But the mistake many teams make is treating them as a one-stop solution, rather than a starting point. The key is to assess your specific use case, environment, and performance needs before you lock into a board level camera, and to work with a supplier who can help you navigate these limitations rather than just selling you a module.
For example, if you’re working on a project that requires custom optics, high dynamic range, or harsh environment resilience, we can work with you to modify a standard board level camera or build a semi-custom module that fits your needs. If you need better low-light performance, we can upgrade the sensor to a larger format or add low-light processing firmware. If you’re dealing with extreme temperatures or vibration, we can source industrial-grade components or modify the housing to be weather-sealed. We’ve helped dozens of clients avoid the pitfalls I mentioned earlier—like the medical device team that needed a custom lens swap, or the agriculture startup that needed dust and moisture protection—by partnering with them early in the design process, not just when they’re ready to order.
If you’re working on a vision-based project and you’re wondering whether a board level camera is the right fit, or if you’ve already run into issues with the limitations I outlined, I’d encourage you to reach out. Whether you’re a small startup prototyping your first product or a large manufacturer launching a new line of industrial equipment, we can help you evaluate your needs, test different camera configurations, and find a solution that balances performance, cost, and timeline.
