Hikvision Wireless Outdoor Siren | DS-PS1-E-WB
The Hikvision DS-PS1-E-WB is a wireless external sounder for the Hikvision AX PRO alarm system. It gives instant audible alerts with a 110 dB buzzer and needs no signal cable to the panel. It uses 433 MHz two-way wireless with AES-128 encryption, reaches up to 900 m in open area, and is rated IP65 for outdoor wall mounting.
Color: White housing

Key Features
Loud 110 dB Buzzer: A 110 dB buzzer makes the alarm clearly heard outside the property. Because the sounder is mounted on an outside wall, the alert is not limited to people inside the building.
Three Alarm Sounds: The sounder has separate sounds for fire, panic and intrusion alarms. This makes it easier to tell what kind of event has been triggered.
Outdoor Protection: An IP65 protection level and a PC+ABS shell let it be mounted on an outside wall. It is specified for -20 °C to 60 °C and 10% to 90% humidity (non-condensing).

Two-Way Wireless: The sounder uses 433 MHz two-way communication with AES-128 encryption and frequency hopping against jamming. The RF distance is up to 900 m in open area, and no signal cable has to be run to the panel.
Battery or 12 VDC Power: It runs on batteries by default, with a battery life of up to 3 years (triggered every two weeks, alerting 90 s each time). It can also be powered from 12 VDC.
Tamper-Proof: Front and rear panel tamper protection reports any attempt to open the cover or pull the sounder off the wall. It can be fully configured remotely through the app and supports multiple enrollment methods.
Who it's for / Works with

Good to know
