What to know before buying

Listing details to confirm

The listing is inconsistent about power: technical details say AC, while the feature text describes solar charging, an 1800mAh rechargeable battery and Type-C backup. It also advertises four modes but names only frequency ultrasound, voice and alarm, and its stated dimensions of 10L x 10W x 10H millimetres appear difficult to reconcile with the described ground stake and wall installation. Confirm the selected unit's power, mode options and physical dimensions before buying. The 110° sensor, 30ft detection and 225m² coverage are listing claims, not independently established performance.
