Nexcom upgrades railway surveillance with innovative solutions

AI has become an integral part of daily life, revolutionizing industries with innovative solutions. The transportation sector, particularly trains, subways, and other rail systems, increasingly relies on image analysis to meet essential safety and operational needs. This technology is crucial for managing crowded environments and optimizing the safety of passengers in real-time.

Overcomplicated wiring layouts not only complicate installation but also increase maintenance costs and lead to potential safety hazards. Additionally, power disruptions in harsh railway environments—such as vibrations, extreme temperatures, or fluctuating power sources. But what if there was a solution that could capture these tech struggles bandits? A solution that simplifies wiring, provides uninterrupted power, and efficiently handles large volumes of data without a hitch.

The combination of NEXCOM nROK 7280-AC5IP and VTK-SCAP provides a powerful and reliable solution, effectively capturing the tech struggles bandits that have long plagued railway surveillance. The nROK 7280-AC5IP supports multiple cameras through PoE, simplifying installation and reducing cable complexity, while the VTK-SCAP-AR-M (Master) ensures stable power by receiving input from the train’s supply and providing a steady 24VDC to the nROK 7280-AC5IP.

Beyond power delivery, the nROK 7280-AC5IP actively monitors railway power stability via RS232, detecting fluctuations and responding accordingly. If the train stops and the main power remains off for an extended period, the
nROK 7280-AC5IP detects the sustained power loss and initiates a controlled OS shutdown, with the VTK-SCAP continuing to supply power to prevent abrupt shutdowns and data corruption. To avoid unnecessary system shutdowns due to brief power dips, the nROK 7280-AC5IP only triggers the shutdown sequence after confirming prolonged power loss.




For extended power backup, up to three VTK-SCAP-S (Slave) units can provide up to 200W of additional power, ensuring uninterrupted operations even in harsh environments. The NEXCOM nROK 7280-AC5IP and VTK-SCAP combine advanced features for optimal performance in demanding environments.

Powered by 26 TOPS AI computing, the nROK 7280-AC5IP enables AI-powered cameras to support key applications such as passenger counting for occupancy monitoring, optimizing load distribution and service planning, and real-time safety surveillance. The system includes 4 x 2.5GbE (IEEE 802.3at/af) and 1 x 2.5GbE (IEEE 802.3at/af/bt) ports. The latter is specifically designed to support advanced cameras, which require higher power consumption. Installation is simplified with M12 X-coded PoE ports, delivering both power and data through a single cable. Additionally, it supports three dedicated drives: one for the operating system and VMS software, and two for storing surveillance footage, which can be configured in RAID to ensure the security and integrity of critical image data, further enhancing both operational efficiency and passenger safety.

On the power side, the VTK-SCAP ensures reliability with its SuperCap-based backup solution, offering over 500,000 charge/discharge cycles for long-lasting durability. With up to 200W of expanded power and operation in temperatures ranging from -35°C to 80°C, the VTK-SCAP ensures uninterrupted power, even in extreme conditions.
