Introduction
CM400E is a compact, high‑resolution depth‑sensing camera developed by Camtech Systems, a manufacturer specializing in imaging solutions for robotics, augmented reality, and industrial automation. The device integrates a 16‑bit CMOS sensor with an active infrared (IR) projector, enabling real‑time depth mapping and color imaging in a single unit. Designed for deployment in environments where size, power consumption, and robustness are critical, the CM400E has been adopted by a range of industries, from warehouse logistics to medical imaging.
History and Development
Origins of Camtech Systems
Camtech Systems was founded in 2008 in Zurich, Switzerland, by a team of engineers with experience in optical imaging and embedded systems. The company began as a small research lab focused on advancing depth‑perception technologies for autonomous vehicles. Early prototypes employed structured‑light patterns projected onto test surfaces to generate depth data, a method that would later underpin the CM400E architecture.
Design Phase (2014‑2016)
The conceptualization of the CM400E began in 2014, driven by the increasing demand for compact depth sensors in robotics and augmented‑reality applications. Engineers sought to merge the high‑quality depth acquisition of active sensors with a low‑profile form factor. The team selected a 4.1 mm × 4.1 mm 4‑K CMOS sensor coupled with an IR laser module capable of emitting up to 15 mW at 850 nm. Key design challenges included minimizing heat dissipation, ensuring adequate illumination for varied ambient light conditions, and maintaining a weight under 120 g.
Prototype and Testing
Initial prototypes were built in late 2015. Extensive lab testing involved calibration against laser scanners and stereoscopic rigs to validate depth accuracy. The prototypes demonstrated sub‑millimeter precision at distances up to 4 m under controlled lighting. Field trials conducted in warehouse settings confirmed robustness against dust, vibration, and temperature fluctuations ranging from –10 °C to 55 °C.
Commercial Release (2017)
The first commercial release of the CM400E occurred in Q2 2017. Marketing positioned the device as an affordable, high‑performance depth camera suitable for both industrial and consumer markets. A limited batch of 1,200 units was supplied to early adopters in the robotics and gaming sectors for beta testing.
Evolution to CM400E Pro (2019)
Based on user feedback, Camtech Systems introduced the CM400E Pro in 2019. Enhancements included a higher frame‑rate mode (120 fps at 640 × 480 resolution) and a reinforced housing to improve shock resistance. Firmware updates expanded the device’s compatibility with new operating systems and provided additional calibration tools.

Features and Capabilities
Real‑Time Depth Mapping
The CM400E employs a structured‑light projection system that encodes a fringe pattern onto the scene. The CMOS sensor captures the deformed pattern, and the onboard processor computes disparity to derive depth. This method provides accurate depth at close ranges and remains resilient to lighting changes, allowing consistent performance in both daylight and low‑light scenarios.
Multi‑Modal Sensing
In addition to depth, the device simultaneously captures color imagery. The dual‑sensor architecture permits alignment of depth and RGB data at the pixel level, facilitating tasks such as semantic segmentation and augmented‑reality overlay. A built‑in infrared filter reduces interference from ambient IR sources, maintaining depth integrity in industrial settings.
Environmental Adaptability
The CM400E is designed to operate in environments with high particulate matter, such as dusty warehouses or outdoor construction sites. Its sealed housing and anti‑fog coatings protect the optics from moisture and dust ingress. The sensor’s thermal management system prevents overheating during extended operation in hot climates.
Software Integration
Camtech’s SDK provides a high‑level API for depth map retrieval, calibration routines, and sensor configuration. The camera is fully compatible with the ROS ecosystem, enabling integration into robotic perception pipelines. Additionally, the device supports streaming via UDP/TCP for real‑time applications in networked robotics and multiplayer AR experiences.
Applications

Criticisms and Limitations
Some users report reduced depth fidelity in environments with strong reflective surfaces, where structured‑light patterns can be distorted. Additionally, the camera’s 120 fps mode is limited to lower resolutions, which may not satisfy high‑precision tasks requiring both speed and detail. Camtech has acknowledged these limitations and is working on algorithmic enhancements to mitigate interference from reflective materials.
Future Development
Camtech’s roadmap for the CM400E series includes the following planned enhancements: higher‑resolution depth output (8 K), adaptive pattern projection for improved reflective surface handling, integration of machine‑learning models for edge‑computing gesture recognition, and extended battery options for mobile robots. Collaborative efforts with academic partners aim to develop new calibration techniques that reduce the need for external calibration targets.
The company is also exploring a modular approach that allows developers to swap sensor components, such as upgrading to a multi‑pixel LiDAR sensor for extreme long‑range mapping, thereby extending the CM400E’s applicability to autonomous vehicles and large‑scale mapping projects.
