The Ultranc-DK-50 Ultra High Sensitivity 4K network camera from TruGem Technologies represents a major breakthrough in low-light imaging. Equipped with a full-frame Exmor sensor, this advanced camera captures stunning 4K color video at just 0.0001 lux, surpassing the SONY VB770 (limited to 0.004 lux). Even in pitch-black environments with no artificial lighting, the DK-50 delivers highly detailed 4K/30fps color footage — and maintains image quality that rivals or exceeds the VB770 under even lower light.
Designed for harsh and complex environments, this camera excels in coastal defense, maritime surveillance, and critical infrastructure protection, offering seamless lens interchangeability and all-weather, 24/7 operational reliability.

Challenges in Coastal Defense Surveillance
As the front line of national security, coastal defense systems are responsible for deterring illegal immigration, smuggling, terrorist infiltration, and hostile reconnaissance. However, they face several critical challenges:
- Poor visibility at night leads to blurry, black-and-white footage, making it hard to identify people or vessels.
- Traditional infrared cameras perform poorly in fog, rain, snow, or under wave interference.
- Surveillance over large distances often lacks clarity and detail.
- Dynamic coastlines and scattered installation points increase deployment and maintenance costs.
Practical Applications of the Ultra High Sensitivity 4K Network Camera Ultranc-DK-50 in Coastal Surveillance
The Ultranc-DK-50 is engineered to meet the demands of complex coastal environments. It provides multiple deployment strategies that solve real-world challenges:
- Nighttime Coastal Patrol Deployment
By installing the Ultranc-DK-50 Ultra High Sensitivity 4K Network Cameraon shorelines, observation towers, and outposts, operators can achieve round-the-clock color video capture without auxiliary lighting. Its ultra-low-light color imaging enables real-time detection and tracking of suspicious vessels or unauthorized activities at night.
✅ Problem Solved:
- Insufficient visibility in dark conditions
- Inability of infrared cameras to detect colors or detailed features
- Port and Dock Surveillance
Deployed in key port areas, the Ultranc-DK-50 can be paired with telephoto E-Mount lenses to conduct ultra-HD surveillance within a 1 km range. It captures clear details of license plates, human faces, and container IDs, even during nighttime operations in cargo terminals, customs zones, and access control points.
✅ Problem Solved:
- Image degradation over long distances
- Difficulty identifying critical objects at night
- Remote Monitoring of Unmanned or Isolated Islands
The Ultranc-DK-50 supports remote data transmission and seamless integration with surveillance platforms. It’s ideal for unmanned or hard-to-access islands, where it enables fully autonomous monitoring with zero on-site personnel. This ensures full-coverage security across coastal borders and maritime perimeters.
✅ Problem Solved:
- Lack of stationed personnel
- Poor signal stability in isolated areas

Key Application Scenarios
- All-Weather Surveillance of Coastlines, Ports, Islands, and Offshore Platforms
China’s vast coastline stretches for tens of thousands of kilometers, with densely distributed ports, islands, and offshore assets operating around the clock. These areas frequently encounter high humidity, strong winds, and extremely low light conditions. The Ultranc-DK-50’s ultra-low-light full-color imaging ensures clear 4K footage even in total darkness or severe weather, providing precise, all-weather remote monitoring and risk prevention — greatly enhancing maritime security readiness.
- Coastal Border Patrol and Intrusion Detection
Coastal border regions are prone to illegal entry, smuggling, and unauthorized maritime activities, especially at night. Traditional night vision systems fall short in recognition and image fidelity. Deployed on watchtowers, patrol routes, and strategic outposts, the Ultranc-DK-50 enables long-range, full-color monitoring combined with intelligent alerts for real-time threat detection — substantially boosting the speed and accuracy of security responses.
- Nighttime Operations & Harsh Environment Security
Tasks carried out by coast guards, military units, or emergency responders often occur under extreme conditions such as blackouts, storms, or rough seas. These missions demand ultra-clear and real-time visuals. When mounted on mobile or fixed platforms, the Ultranc-DK-50 delivers high-frame-rate, low-noise 4K color video, offering vital visual support for mission-critical operations and enabling fast, accurate decision-making in high-risk environments.
