Hikvision Wireless Temperature and Humidity Detector | DS-PDTPH-E-WB
The Hikvision DS-PDTPH-E-WB is a wireless temperature detector with a 2.7-inch display for the Hikvision AX PRO alarm system. It measures from -10 °C to 55 °C on its own, or from -35 °C to 99 °C with the included external probe, and talks to the panel over AES-128 encrypted two-way 433 MHz wireless with up to 800 m range in free space.

Big On-Screen Display: The 2.7-inch screen shows the readings on the detector itself, so the conditions can be checked at a glance without opening the app.
Two Measuring Modes: Used standalone, the detector measures -10 °C to 55 °C. With the included external probe, the temperature range extends to -35 °C to 99 °C, which lets you measure a spot away from the detector body.

Secure Tri-X Wireless: Two-way RF at 433 MHz with AES-128 encryption and frequency hopping against jamming, with up to 800 m range in free space. It is fully configurable remotely through the app and can be enrolled by power-up, remote ID or QR code.
Battery Powered: Two AAA batteries (3 V) give up to 2 years of standby time. The compact 62.6 x 62.6 x 18 mm body weighs 73.5 g and mounts on a wall, with front and rear tamper protection.
Who it's for / Works with
