DTNVS / NNVT-5 is a reliable binocular night-vision system that combines the lightweight, ergonomic DTNVS housing with NNVT-5 / NVT-5 image-intensifier tubes available in two phosphor variants: P43 (green) and P45 (white).
This configuration offers an excellent balance of image quality, reliability, and cost, delivering an FOM in the 1600–1800 range, SNR above 25, and resolution from 64 lp/mm.
The DTNVS housing is made from magnesium alloy, features IP68 waterproof protection, includes automatic shut-off when flipped up, and supports both CR123A and external power input.

Comment / Quality Level
The NNVT-5 / NVT-5 tubes are an economical Gen 2+/3- class solution that delivers good light sensitivity and an acceptable noise level for training and observation tasks.
P45 White Phosphor models provide a more natural spatial perception, while P43 offers traditional contrast and better efficiency in very low-light conditions.
In terms of performance, these tubes outperform most entry-level commercial Gen 2+ systems, providing stable imaging and durability at a significantly lower cost than contract-grade Gen 3.
The DTNVS housing adds modern ergonomics, easy maintenance, and modularity.
Suitable For
• Training centers and instructors who require affordable yet capable devices for exercises and courses.
• Volunteer and search-and-rescue organizations equipping personnel with mid-range night-vision systems.
• Security operators who need stable nighttime performance without excessive cost.
• Airsoft groups and civilian users seeking realistic night-vision capability without paying for full Gen 3.
• Reconnaissance teams and reservists who value ease of maintenance and repairability.
