Prama PT‑NRAS2B32‑K4 is a 32‑channel AI‑enabled Network Video Recorder (NVR) for IP cameras that supports up to 32 IP camera inputs with a total incoming bandwidth of 256 Mbps. The unit provides 4 SATA HDD interfaces (up to 10 TB each, 40 TB total) and uses a 1.5U, 19‑inch‑rack‑mount case with 16 alarm inputs and 4 relay outputs (16/4 configuration). So, it suits large‑scale sites that need many‑camera AI recording, big storage, and integration with external sensors and sirens.

Therefore, it works well with 4K, 12MP, 8MP, and 4MP IP cameras over standard LAN cabling.

Video input, decoding, and bitrate

• Up to 32 IP camera channels.

• Incoming bandwidth: up to 256 Mbps; outgoing bandwidth typically up to 160 Mbps (often up to 128 Mbps for TLS‑encrypted streams).

• Decoding configurations (common spec):

  • AI‑on: up to 2‑ch @ 12 MP, 3‑ch @ 8 MP, 6‑ch @ 4 MP, or 12‑ch @ 1080p.

  • AI‑off: up to 2‑ch @ 12 MP, 3‑ch @ 8 MP, 6‑ch @ 4 MP, or 12‑ch @ 1080p (playback‑style mode).

• Video formats: H.265+ / H.265 / H.264+ / H.264.

• Maximum recording resolution: 12 MP, with common options at 8 MP, 6 MP, 5 MP, 4 MP, 3 MP, 1080p, 720p, VGA, and CIF‑style.

• Supports 16‑channel synchronous playback.

This means you can mix high‑resolution and lower‑resolution streams while staying within the 256 Mbps cap and still using AI features.

AI features and storage

• Uses Prama Aisense AI for face detection, capture, comparison, and 32‑channel human/vehicle analysis on suitable cameras.

• Typical face‑recognition mode:

  • 1‑ch facial recognition from video stream, or

  • 4‑ch facial recognition from face‑picture libraries.

• Face‑library supports multiple libraries and thousands of face images (around 20,000 images in 4×16‑library‑style setups).

• 4 SATA HDD bays, each up to 10 TB, for up to 40 TB total storage.

• H.265+ compression reduces storage usage by up to about 75% compared with H.264.

• Recording modes: continuous, motion‑triggered, scheduled, and event‑based (with motion/Human/vehicle‑based events).

So, the NVR delivers smart alerts, efficient storage, and long‑term recording without extra enclosures.
