NAC Memrecam MX

The NAC Memrecam MX a high-speed multi-camera system that can connect up to 8 compact camera heads with full HD sensor to one MX-5 main unit for synchronized shooting.

Designed specifically for car crash test and collision experiments.

The new design mounts memory on the camera head, the cable that connects the camera head and the main body has been made thinner and more robust, and high-speed shooting with full HD (2 megapixel) resolution is possible.

Description

NAC Memrecam MX

Designed specifically for car crash experiments

The MEMRECAM MX is a multi-camera system designed with an unprecedented concept specializing in automobile development.
With the use in collision experiments in mind, we improved the shock-resistant performance and enhanced the specifications of the camera such as high definition, and the new design with a built-in memory in the camera head reduced the diameter of the cable connecting the camera head and the main body. Realization and solidification.

Compliant with new regulations for collision testsNAC MX camera

With new test methods such as EuroNCAP and IIHS, the number of high-speed cameras installed has become stipulated, and we have released an 8ch model that meets these requirements. In addition to M-Cam, MX-5 can select 3 types of camera heads, M-Cam MFT and M2-Cam, and it is possible to operate with different camera heads and different camera settings depending on the shooting location.

Variety of compact camera heads available

M2-CamNAC MX camera

Is a compact size and has improved resolution, which is required for on-vehicle cameras for collision tests. A 33 x 33 x 45 mm compact camera head has a built-in recording memory and an eMMC for storing secondary data to improve durability in collision tests.

Micro Four Thirds compatible M-Cam MFT

A new camera head M-Cam MFT compatible with Micro Four Thirds has been added to the lineup. It uses the same sensor as the conventional M-Cam, and while maintaining high sensitivity, full HD, and 2,000 frames / second, it can be electrically controlled with a commercially available lens of Micro Four Thirds mount. The lens can be adjusted from a remote location, such as the ceiling of the collision test site, the underground pit, remote shooting of military-related items, and external control of the engine bench, enabling new operations that are different from before.

Connect up to 8 cameras to a small DRP

Equipped with a 2-megapixel sensor (excluding M2-Cam), a G-resistant camera head with a built-in 4GB memory captures high-definition video data. Now more accurate analysis is possible. In addition, the compact shape of the main unit makes it suitable for shooting environments where space is limited, such as in vehicles.

Uses a thin coaxial cable

The diameter of the cable is φ7 mm and the 360 ​​° rotating connector reduces camera installation restrictions and operational complexity. In addition, robustness and ESD resistance are enhanced to prevent problems during shooting.

Viewfinder remote control

You can adjust the angle of view and set the shooting conditions by connecting the tablet device to the wired / wireless LAN.

Accessories that are convenient for shooting

In addition to the plate-type LED lighting that can be installed even when shooting onboard, there is a lineup of lighting that can be selected according to the shooting environment, such as G-resistant LED lighting. By illuminating not only the average illuminance value but also unevenness, image quality and analysis accuracy can be improved. It is also possible to use the GX-HUB that shoots multiple systems synchronously, such as conventional products.
