What Is a 4G LTE Solar Security Camera?

A 4G LTE solar security camera uses cellular data (SIM card) instead of Wi-Fi for connectivity, making it ideal for remote locations without internet access — farms, construction sites, rural properties, vacation homes, and areas far from routers. Combined with a solar-rechargeable battery, it operates completely wire-free: no power cable, no internet cable, no Wi-Fi required. Just mount it, insert a SIM card, and it connects over 4G LTE cellular network.

YI 4G LTE Solar Camera Overview

This camera delivers 3MP 2304×1296 video, powered by a 7500 mAh rechargeable battery with included solar panel. It features 270° pan and 90° tilt, PIR human detection (120° / 10 m range), infrared and full-color night vision with spotlights, two-way audio, active deterrence (spotlight + siren), and IP65 weather protection. It connects over 4G LTE cellular network — no Wi-Fi needed.

Key Features

• 3MP video — 1/3" Color CMOS sensor captures clear 2304×1296 images with a 4 mm focal length and 88.3° diagonal field of view.
• 4G LTE connectivity (no Wi-Fi needed) — uses a SIM card for cellular data; ideal for locations without internet access. US variant supports LTE-FDD B2/B4/B5/B12/B13/B66/B71.
• 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 with 120° detection angle and 10 m range reduces false alerts from non-human movement.
• 4× 950nm IR LEDs + spotlights — infrared illumination for discreet night surveillance plus white 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 through the app.
• IP65 weather protection — rated for outdoor use in rain, dust, and temperature changes year-round.
• Flexible storage — microSD card up to 128 GB or optional cloud recording.
• FCC certified (US variant).

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. 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

US variant LTE bands: LTE-FDD B2, B4, B5, B12, B13, B66, B71 (compatible with major US carriers). Confirm 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 is more accurate than pixel-based motion detection — it triggers on actual human presence rather than swaying branches, passing cars, or changes in lighting, significantly reducing false alerts.

Night Vision with IR & Spotlight

Four 950nm 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. Two modes are available:

• 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 before the person approaches further. This can also be triggered manually through the app.

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
• Driveways and garages far from the house router
• Properties needing active deterrence (spotlight + siren)
• Locations with adequate sunlight for indefinite solar-powered operation

Frequently Asked Questions

Does this camera need Wi-Fi?
No. It connects over 4G LTE cellular network using a SIM card. Wi-Fi is not required. This makes it ideal for remote locations without internet access.

What SIM card does it use?
A standard 4G LTE SIM card from a compatible carrier. The US variant supports LTE-FDD bands B2/B4/B5/B12/B13/B66/B71. Check band compatibility with your local carrier before purchase.

How long does the battery last?
Battery life depends on usage (recording triggers, live viewing frequency, and detection events). The included solar panel recharges the 7500 mAh battery with sunlight. In locations 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 and why is it better?
PIR (Passive Infrared) detects human body heat, not just pixel changes. This means fewer false alerts from wind, rain, shadows, or animals compared to basic motion detection. The 120° detection angle covers a wide area up to 10 meters.

Can I view the camera remotely?
Yes. The YI IOT app (iOS & Android) provides live viewing, pan/tilt control, two-way audio, and alert management over the 4G LTE connection from anywhere.

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

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