Solar Alarm Lamp with Remote Control N911C: Motion-Activated Strobe and Siren
A security camera records what happens. This solar alarm lamp stops it from happening in the first place. The N911C combines a high-intensity red LED strobe with a 129 dB siren that activates on motion detection, creating an immediate visual and audible deterrent loud enough to be heard across a residential property, farm yard, or commercial parking area. Most opportunistic intruders abandon the attempt the moment a screaming alarm and flashing light expose their presence.
The unit runs entirely on solar power via a built-in 5V monocrystalline panel that charges the internal lithium-ion battery during daylight hours. A full charge takes approximately 4 to 6 hours of decent sunlight and provides 10 to 12 hours of operational runtime. For extended overcast periods or winter months where solar input drops, a USB charging port serves as a backup power method so the unit never goes offline when you need it most.
A remote control lets you select from four operating modes without climbing up to the unit:
-
Mode 1: 24-hour operation with flashing and alarm
-
Mode 2: 24-hour operation with flashing only (silent)
-
Mode 3: Night-only operation with flashing and alarm
-
Mode 4: Night-only operation with flashing only (silent)
The silent modes are useful when you want a visible warning beacon without disturbing neighbours, while the night-only modes conserve battery by disabling the system during daytime hours when the property is occupied or monitored by other means. Remote range extends up to 200 metres (656 ft) in open areas without interference, so you can arm or switch modes from well inside your home.
The motion sensor detects movement at 5 to 8 metres (16 to 26 ft), though detection distance varies with ambient temperature as PIR sensors rely on the contrast between body heat and the surrounding environment. In cooler conditions, detection range extends further. In very hot weather where background temperatures approach body temperature, the effective range shortens.
The housing is moulded from ABS plastic with an IP65 water-resistant rating, meaning it handles direct rain, dust, and general outdoor exposure without degradation. The 8 red LEDs produce a highly visible strobe pattern that draws attention from a distance, particularly effective after dark. At 8.9 × 5.8 × 14 cm, the unit is compact enough to mount above a gate, on a fence post, under an eave, or on a garden wall using the included bracket and screws.
No wiring, no electrician, no monthly monitoring fees. Mount it where the sun hits the panel, aim the sensor toward the approach you want covered, and the unit takes care of itself from that point forward.
