Prama PT‑NRAS2A04‑K1 is a 4‑channel AI‑enabled Network Video Recorder (NVR) for IP cameras. It supports up to 4 IP camera channels with a total incoming bandwidth of 40 Mbps. The unit has a 1U, 315‑style case and includes 1 SATA interface for HDD storage. So, it suits small‑to‑mid‑sized sites that need compact, high‑resolution AI recording.
Therefore, it works well with 4K / 12MP / 8MP / 4MP IP cameras on existing LAN cabling.
Video input and resolution
Up to 4 IP camera channels.
Supports high‑resolution streams up to 12 MP on 1 channel, 8 MP on 2 channels, or 4 MP on 4 channels.
Recording resolution options include 12 MP, 8 MP, 6 MP, 5 MP, 4 MP, 3 MP, 1080p, 720p, VGA, and lower CIF formats.
This means the NVR can handle multiple high‑resolution cameras in parallel without over‑saturating the 40 Mbps bandwidth.
AI features and storage
Uses AI‑Sense / deep‑learning engine for face detection, facial recognition, and human/vehicle filtering.
Face‑storage capacity supports thousands of face images for smart search and alerts.
1 SATA interface accepts up to 10 TB HDD for long‑term recording.
So, you get intelligent alerts and searchable events instead of pure continuous recording.
