Generic Solar Infrared Wireless Doorbell & Driveway Alarm

A weatherproof solar infrared wireless doorbell and driveway alarm kit that uses two solar motion sensors and one plug-in receiver to detect movement up to 200 meters and announce alerts with selectable melodies and volume.

This compact security kit combines passive infrared motion detection, long-range wireless transmission, and solar charging so you can monitor driveways, gates, yards, and entrances without wiring or frequent battery swaps. The sensors capture heat and motion within a wide 120° field, the receiver plugs into standard mains power, and you can tune sensitivity, volume, and melody to suit pets, visitors, or vehicles. The system is designed for straightforward installation and flexible pairing between multiple sensors and receivers.

How reliable is the motion detection outdoors?

The sensors use PIR (passive infrared) technology to detect body heat and movement across a 120° horizontal angle. Sensitivity levels (low/medium/high) cover short to long detection ranges, and the solar panel plus Type-C charge port keeps the sensor powered for months on standby.

• Detection angles: 120° horizontal for broad coverage
• Sensitivity ranges: low (5–8m), medium (8–12m), high (13–16m)
• Solar panel: monocrystalline silicon 5.5V 100mA with Type-C backup charging
• Standby and transmission: over 4 months standby, >9000 transmissions per full charge

What is the wireless range and pairing flexibility?

The kit operates on 433MHz FSK and is engineered to deliver practical line-of-sight performance up to 200 meters in most real-world conditions. You can pair one receiver with multiple transmitters or link one sensor to several receivers for custom coverage across properties.

• Typical working range: 100–200 meters; tested up to ~600ft in open spaces
• Receiver voltage: 110–240V plug-in for consistent indoor alerts
• Flexible pairing: one receiver can accept multiple sensors, and vice versa
• Proven resilience: tested through trees, rain, heat, and snow

How do I set up sounds, volume, and installation placement?

Setup is tool-free: mount the motion sensor at roughly 1.3 meters high for optimal detection, plug the receiver into a mains socket, and follow pairing steps. Choose from 38 melodies and four volume settings, plus a visual indicator light for silent alerts.

• Melodies: 38 selectable tunes to differentiate sensors or locations
• Volume options: high, medium, low, or mute with indicator light
• Recommended height: ~1.3 meters for best detection range and reliability
• Mounting: weatherproof housing for permanent outdoor installation

What power and durability can I expect from the solar transmitter?

The transmitter combines a monocrystalline solar panel with a rechargeable 3.7V/500mA battery and a Type-C input for rainy periods. One full solar charge equates to thousands of transmissions and practical daily operation from minimal sunlight.

• Battery: 3.7V/500mA rechargeable cell with Type-C charging option
• Solar spec: monocrystalline 5.5V 100mA panel, full charge in ~8 hours sun
• Daily use: one sun hour per day can meet typical daily power needs
• Durability: weatherproof casing rated for outdoor exposure

Who is this for: this kit is suitable for homeowners, small business owners, and caretakers who need a no-wires, low-maintenance alert system for driveways, gates, yards, or entrances. It works well for monitoring vehicle access, notifying you when visitors arrive, and providing extra awareness for child or elder movement outdoors. Choose this kit if you want an easy-to-install, solar-powered alarm with flexible pairing, adjustable sensitivity, and audible plus visual notifications.
