What Is a Dual-Lens 4G LTE Solar Security Camera?

A dual-lens 4G LTE solar security camera combines two independent lenses in a single device with cellular connectivity and solar-rechargeable battery power. The dual-lens design provides wider coverage than a single lens — one lens can remain fixed on a key area while the other pans to track movement. 4G LTE means no Wi-Fi or internet is required; a SIM card connects the camera over cellular networks. Solar + battery means no power cable. It is a fully wire-free solution for remote outdoor monitoring.

YI Dual-Lens 4G LTE Solar Camera Overview

This camera features a dual-lens 3MP (2304×1296) design with a 1/4.5" Color CMOS sensor, 7500 mAh rechargeable battery with included solar panel, 270° pan and 90° tilt, PIR human detection (120° / 10 m), 8× 850nm IR LEDs for infrared and full-color night vision, two-way audio, active deterrence (spotlight + siren), and IP65 weather protection. Connects over 4G LTE — no Wi-Fi needed.

Key Features

• Dual-lens 3MP video — 1/4.5" Color CMOS sensor, 2304×1296 resolution, 4 mm focal length, 88.3° diagonal field of view. Two lenses provide wider simultaneous coverage.
• 4G LTE connectivity (no Wi-Fi needed) — uses a SIM card for cellular data. US/EU/CN frequency band variants available.
• 7500 mAh solar battery — rechargeable battery + included solar panel for true wire-free operation. No power cable needed.
• 270° pan & 90° tilt — remotely control viewing direction through the YI IOT app.
• PIR human detection (120° / 10 m) — passive infrared sensor reduces false alerts from non-human movement.
• 8× 850nm IR LEDs + spotlights — infrared for discreet B/W surveillance, spotlights for full-color night vision and active deterrence.
• Active deterrence — bright white spotlights + audible siren activate when intrusion is detected.
• Two-way audio — built-in microphone and speaker for remote communication.
• IP65 weather protection — rated for year-round outdoor use.
• Flexible storage — microSD card up to 128 GB or optional cloud recording.

Why Dual-Lens?

A single-lens camera must choose between a fixed view or panning to a new direction — you can't do both at once. The dual-lens design solves this:

• Lens 1 (fixed/wide) — maintains continuous coverage of a key area (e.g. entrance, gate)
• Lens 2 (PTZ) — pans 270° and tilts 90° to track movement or check other directions on demand

Together, the two lenses provide wider situational awareness from a single mounting point without creating blind spots during rotation.

No Wi-Fi? No Problem — 4G LTE Cellular Connectivity

Unlike Wi-Fi cameras that require a router within range, this camera connects over 4G LTE cellular networks using a standard SIM card. US, EU, and CN frequency band variants are available. This makes it the right choice for:

• Rural farms and livestock areas with no internet
• Construction sites and temporary installations
• Vacation homes and cabins checked only seasonally
• Garages, sheds, and outbuildings far from the router
• Any location where running network cable is impractical

Confirm 4G LTE band compatibility with your local carrier before purchase.

Solar + Battery = True Wire-Free

The 7500 mAh built-in rechargeable battery powers the camera without any power cable. The included solar panel keeps the battery topped up with sunlight. In locations with adequate sun exposure, the camera can operate indefinitely without manual recharging.

PIR Human Detection (120° / 10 m)

The passive infrared (PIR) sensor detects human body heat within a 120° angle and up to 10 meters away. PIR detection triggers on actual human presence rather than swaying branches, passing cars, or changes in lighting — significantly reducing false alerts compared to pixel-based motion detection.

Night Vision with 8× IR LEDs & Spotlights

Eight 850nm infrared LEDs provide clear black-and-white footage in complete darkness. White spotlights activate for full-color night vision or as part of the active deterrence system:

• Infrared mode — discreet B/W surveillance, invisible to the human eye
• Full-color mode — white spotlights illuminate the scene for color footage at night

Active Deterrence: Spotlight + Siren

When the PIR sensor detects an intruder, the camera can automatically activate bright white spotlights and an audible siren to warn and deter. This can also be triggered manually through the app for on-demand warnings.

Two-Way Audio

A built-in microphone and speaker enable real-time two-way communication. Talk to visitors, delivery drivers, or issue verbal warnings directly through the YI IOT mobile app.

Technical Specifications

Best For

• Remote farms and livestock areas — 4G LTE works where there is no Wi-Fi or internet
• Construction sites — temporary installations with no permanent power or network
• Vacation homes and cabins — monitor seasonally without maintaining a router
• Entrances and gates — dual-lens covers both the approach and surroundings simultaneously
• Properties needing active deterrence (spotlight + siren) at the perimeter
• Locations with adequate sunlight for indefinite solar-powered operation

Frequently Asked Questions

What is the advantage of dual-lens over single-lens?
A single-lens camera must choose between watching a fixed area or panning elsewhere — it can't do both. The dual-lens design lets one lens stay fixed on a key zone while the other rotates, providing wider coverage without blind spots.

Does this camera need Wi-Fi?
No. It connects over 4G LTE cellular network using a SIM card. Wi-Fi is not required.

What SIM card does it use?
A standard 4G LTE SIM card from a compatible carrier. US, EU, and CN frequency band variants are available. Confirm compatibility with your local carrier before purchase.

How long does the battery last?
Battery life depends on usage. The included solar panel recharges the 7500 mAh battery with sunlight. With adequate sun exposure, the camera can operate indefinitely without manual recharging.

Is the solar panel included?
Yes. A solar panel is included in the box.

What is PIR detection?
PIR (Passive Infrared) detects human body heat, not just pixel changes. This means fewer false alerts from wind, rain, shadows, or animals. The 120° detection angle covers up to 10 meters.

Does it require a subscription?
No subscription is required for local recording on microSD (up to 128 GB). Cloud storage is optional.

Is it waterproof?
It is rated IP65 — protected against water jets and dust. Suitable for year-round outdoor use.
