The Ajax NVR DC (16-ch) Black brings Ajax Systems' video management capabilities to direct current infrastructure in medium-to-large enterprise sites, operating across a flexible voltage range of **12–24 V⎈ (DC)**. Housed in a compact matte black casing, this network video recorder is engineered for deployments where standard 230V AC mains are unavailable or where battery backup, solar power arrays, or low-voltage DC grid lines are preferred. The unit operates standalone via the mobile app without requiring a central station hub panel.
The proprietary **JetSparrow** software architecture processes high-bandwidth video packets with microsecond synchronization, allowing operators to browse timeline archives instantly with zero buffer lag, even in 4K configurations across 16 channels. Embedded **Artificial Intelligence (AI)** algorithms classify humans, moving vehicles, and pets on the fly for rapid security filtering.
The fanless thermal design delivers completely silent operation and optimized energy efficiency. Video feeds are secured by end-to-end **TLS** encryption. The unit accommodates an internal 3.5" SATA hard drive slot supporting up to 16 TB. Note: The external 12–24 V DC power supply is not included in the standard package and must be supplied according to installation requirements.
