ZHENGZE adds thermal imaging and GPS to firefighter PASS gear

Nanjing ZHENGZE Technology Co., Ltd. is pitching an integrated firefighter rescue device that combines PASS alarms with thermal imaging, video, communication and positioning. The company says the system is built to improve situational awareness and rescue speed in smoke-filled, high-risk environments.

Why it matters: - Firefighters often carry separate tools for distress signaling, thermal imaging, communication and navigation. - ZHENGZE’s integrated device aims to reduce gear load and simplify decision-making in zero-visibility emergencies. - The combined system is designed to help crews find downed responders, track hazards and share live information with command centers faster.

What happened: - Nanjing ZHENGZE Technology Co., Ltd. announced the RHJ800/TS Intelligent Thermal Imaging Rescue Device for Individual Firefighters. - The company says the device builds on PASS safety functions and adds thermal imaging, visible-light imaging, voice communication, positioning and video recording. - ZHENGZE identified itself as a supplier of PASS firefighter equipment and said the company was established in March 2004.

The details: - The RHJ800/TS includes infrared thermal imaging, visible-light optics, real-time on-site video recording, push-to-talk voice communication, Bluetooth connectivity, digital compass orientation, auxiliary LED lighting and dual-mode satellite and inertial indoor-outdoor positioning. - The device uses an uncooled focal plane array sensor and offers Full-Color, Hotspot, White-Hot and Black-Hot display modes. - The built-in 3.1-inch color display shows thermal readings and temperature tracking data. - The system captures photos and video and can transmit live tactical feeds from inside hazardous zones. - A tri-axial accelerometer triggers a pre-alarm after 30 seconds of no motion and a full alarm after 45 seconds. - The alarm uses a high-decibel siren and red LED directional strobe lights. - A manual SOS button can trigger the emergency alarm immediately. - The device monitors ambient temperature and automatically activates a warning alarm when external temperature exceeds 80 degrees Celsius. - Bluetooth links the device with biometric wristbands, heads-up displays, portable gas detectors and smart SCBA back-frames. - The breathing apparatus connection can surface cylinder pressure, residual air and consumption data on the main screen. - Gas detector alerts are displayed immediately when concentrations cross permissible thresholds. - A 4G public cellular module with hot-swappable SIM support enables cloud-based scheduling and data transmission. - Audio, thermal video and spatial coordinates can be streamed to local command units and regional headquarters. - The device includes Black Box storage that logs operational parameters, sensor history, temperature changes, alarms and voice transmissions. - ZHENGZE says the housing uses high-impact, flame-retardant polymers and meets IP68 ingress protection standards. - The company says its production facility covers more than 5,000 square meters and employs more than 200 people. - ZHENGZE says its research and development team has secured more than 100 core patents. - The company says it provides custom design, mold production and global certification support. - The company’s website is More information.

Between the lines: - The product reflects a broader push in emergency response equipment toward consolidation of multiple functions into one rugged platform. - ZHENGZE is positioning itself as both a manufacturer and systems integrator rather than a simple assembler. - The focus on video, cloud transmission and sensor fusion suggests demand for more data-rich firefighter tools, not just alarms.

What's next: - ZHENGZE is directing procurement and technical inquiries to its website. - The company is likely to push the RHJ800/TS as part of a wider portfolio of intelligent rescue equipment for domestic and international buyers. - Fire departments evaluating the device will need to weigh added functionality against complexity, training and procurement costs.

The bottom line: - ZHENGZE’s pitch is straightforward: combine PASS safety, thermal imaging and location tracking in one device so firefighters carry less and commanders see more.
