Prama PT‑NC146D3‑WNRAM(D2) is a 4 MP motorized varifocal bullet IP camera with Veri‑Focal lens (2.8–12 mm), IR + white‑light illumination, built‑in microphone, micro‑SD card slot (up to 512 GB), and 1 alarm input / 1 alarm output + 1 audio input / 1 audio output. It supports 1920 × 1080 @ 25/30 fps, 120× WDR, and H.265/H.264 compression, powered by DC 12 V and PoE in an IP67‑rated housing.

Therefore, this camera suits flexible outdoor monitoring, such as roads, parking lots, large perimeters, and wide‑area entrances, where you need remote focal‑length adjustment, bright IR/white‑light night vision, 1‑way audio, on‑camera recording, and direct integration with external alarms and sirens.

Veri‑Focal motorized varifocal lens

• Lens type: Motorized varifocal lens (2.8–12 mm).

• Veri‑Focal feature:

  • Lens can be adjusted remotely from the NVR/CMS software (no manual zoom cap needed).

  • 2.8 mm: wide view for large areas.

  • 12 mm: narrow/telephoto view for long‑range detail.

• This allows one‑time installation and remote FOV adjustment later, ideal for fixed‑mount outdoor bullets.

Image sensor, resolution, and low‑light

• Sensor: 1/2.9″ Progressive Scan CMOS.

• Resolution: 1920 × 1080 (4 MP) at 25/30 fps.

• Low‑light performance:

  • Color: 0.005 Lux @ (F1.6, AGC ON) – visible in very dim ambient light.

  • B/W: 0 Lux with IR – full black‑and‑white video using IR LEDs.

• With 120× WDR, BLC, HLC, and 3D DNR, the camera balances scenes with bright back‑light, glare, and low‑light foreground.

Dual‑mode illumination: IR + white light

• Supplement‑light types: IR + White Light.

• Supplement‑light range: up to 30 m (IR‑only and white‑light‑only).

• White‑light mode gives color‑scene visibility at night (e.g., number plates, clothing, or small objects).

• The camera is typically mounted outside with IP67 protection for dust and water‑jet resistance.

Audio, storage, and I/O

• Built‑in microphone: captures on‑scene audio (vehicles, voices, etc.).

• Micro‑SD slot: supports cards up to 512 GB for on‑camera recording (event‑only or continuous) when no NVR is present.

• Alarm I/O:

  • 1 alarm input (e.g., PIR, door contact, motion sensor).

  • 1 alarm output (e.g., relay to siren, strobe, or gate).

• Audio I/O:

  • 1 audio input (for external mic) and 1 audio output (for external speaker).

So, this camera can act as a self‑contained mini‑surveillance node with alarms, audio, and local storage.

Power, encoding, and protection

• Video encoding: H.265 / H.264; H.265 reduces bandwidth and storage.

• Power: DC 12 V and PoE (802.3af) over the Ethernet cable.

• Environment: IP67 – suitable for outdoor wall or pole mounting.

• Use cases: road surveillance, parking‑lot perimeters, building entrances, ATMs, and wide‑area outdoor monitoring where you need remote focal‑length control, white‑light night‑vision, on‑camera recording, and alarm‑triggered siren/strobe.
