Overview of Hikvision DS-PDHT-E-WB
The Hikvision DS-PDHT-E-WB is a wireless heat detector that raises an alarm when the ambient temperature exceeds 57℃, making it a good fit for kitchens, garages, laundry rooms and other spaces where a smoke detector may cause nuisance alarms. A built-in buzzer of at least 85dB at 3 m gives a local warning, with alarm sound interlink and self-health check support. It reports over two-way 433MHz RF with AES-128 encryption and up to 1Km free-space range, and enrolls by power-up, Remote ID or QR code. Battery life is 10 years for the standalone sensor and 5 years for the RF wireless part. Suitable for villas, apartments, restaurants and hotels.
