License Plate Reader 4MP 9-22mm
Purpose-built to capture plates day & night, this 4MP LPR camera package uses a 9–22 mm motorized lens so we can dial in the exact view for your lane, drive, or gate. It’s designed to read plates at approach speeds typical of entrances and lots, with long-range IR and pro imaging (WDR, H.265) for reliable results in glare, headlights, and low light.
Why Choose This with Smart Shield Systems
- Lens tuned for your distance: we select and remotely fine-tune the 9–22 mm range for tight plate framing without moving the camera. Comparable LPR builds commonly ship with 2.8–12 mm, 8–32 mm, or 10–40 mm options, which we also use when a site calls for them.
- Configured for your speeds & lighting: we set shutter/WDR/IR for clean plates at your typical approach speed and ambient light. (Our site package notes capture below ~60 mph and IR reach up to ~260 ft, location dependent.)
- End-to-end Alarm.com/NVR/VMS integration: H.265 streams, PoE power, and ONVIF mapping verified for your recorder.
Key Features
- 4MP LPR imaging optimized for single-lane capture; deep WDR for headlight/backlight.
- Motorized 9–22 mm lens for precise plate framing at common driveway/gate distances (other ranges available when needed).
- Night performance: dedicated IR—our package page specifies up to ~260 ft; many LPR models list ~60–100 ft depending on lens/LEDs.
- Efficient recording: H.265/H.265+ reduces bandwidth & storage; supports multi-stream recording.
- Rugged build: IP67 weather rating and often IK10 vandal resistance depending on housing.
- Open compatibility: ONVIF Profile S/G/T on many LPR models for broad NVR/VMS support.
Product Specifications (At-a-Glance)
- Resolution / FPS: up to 2688×1520 @ 25–30 fps (model dependent).
- Lens: Motorized 9–22 mm (package spec). For reference, common LPR options include 2.8–12 mm, 8–32 mm, 10–40 mm; we match focal length to your distance.
- Capture envelope: tuned for single-lane entries/exits and slow-to-moderate speeds; our site package cites < ~60 mph. Some 4MP LPRs certify up to ~75 mph in specific mounting windows.
- Illumination: integrated IR, with real-world plate capture distances dependent on lens, angle, and mounting (examples: ~98 ft on a 10–40 mm unit; longer on high-output builds).
- Codec / Storage: H.265/H.265+; many models include microSD (up to 256–512 GB) for edge backup.
- Power / Network: PoE (IEEE 802.3af/at); ONVIF S/G/T support common.
Compatibility Notes
- Recorders & platforms: Works with most ONVIF-compatible NVRs/VMS; we verify stream/event mapping (plate text, snapshots) during commissioning.
- Use case fit: Hikvision’s 4MP LPR bullets are designed for single-lane, slow-speed entrances; Dahua’s 4MP ITC series supports higher speeds with specific mounting geometry. We choose accordingly.
Popular Use Cases
- Community or commercial gate arms (open/deny by plate list)
- Driveway & parking entries with recurring vehicles
- Loading areas and service lanes needing reliable plate IDs after dark
Frequently Asked Questions
Our package page lists plate capture below ~60 mph with IR reach up to ~260 ft (scene dependent). Some 4MP LPR models are rated for up to ~75 mph when mounted at specific heights/angles/distances. We’ll model your lane before installation.
That range gives tight, readable plates at common driveway/gate distances. If your lane is longer/shorter, we’ll select another LPR lens (e.g., 2.8–12 mm, 8–32 mm, or 10–40 mm) to keep characters large and sharp.
Yes. LPR cameras use fast shutter + IR and True WDR to cut glare and freeze motion, producing clean, high-contrast plates after dark.
In most cases, yes. Typical LPR models support ONVIF S/G/T, PoE, and H.265 streams; we validate compatibility and set plate snapshots/overlays on your recorder.
We often include edge recording (microSD) as a buffer and pair it with your NVR retention for redundancy.
