Description
The Uniview EK-S31P4D44T1-V2 is a complete 4-channel, 4-megapixel IP video surveillance kit. It is designed to deliver reliable, easy-to-deploy security for residential properties, offices, and small to medium businesses. Built as a true plug-and-play solution, it simplifies installation. In addition, it provides the performance and coverage needed for everyday protection.
At the heart of the system is the NVR301-04S3-P4 network video recorder, which features 4 independent PoE network ports for direct camera connection and streamlined setup. This makes it easy to build a dependable surveillance system without the need for additional power infrastructure. As a result, it helps reduce installation time and complexity.
The kit includes four EC-D4F28M 4MP vandal-resistant outdoor dome cameras, each engineered for durability and clear image capture in demanding environments. With 4MP resolution at 2560 × 1440 and support for 25 frames per second, the system delivers sharp, detailed video. Consequently, users can monitor people, property, and activity with confidence.
To maximize storage efficiency, the EK-S31P4D44T1-V2 supports Ultra 265, H.265, and H.264 video compression profiles. It also comes equipped with a 1 TB surveillance-grade hard drive. This provides ample storage for recorded footage while maintaining efficient performance across the system’s maximum throughput of 64 Mbps.
Designed for outdoor use, the cameras feature Smart IR tracking with visibility up to 98 feet (29.87 m). They also have an IP67 ingress protection rating for dependable operation in harsh weather conditions. The system also fully complies with Section 889 of the National Defense Authorization Act (NDAA). Therefore, it is a secure and standards-conscious choice for organizations and homeowners seeking a trusted surveillance solution.
