Dahua DHI-ARM7011-W2(868) wireless relay — a compact actuator module for remote control of electrical circuits as part of a wireless security system. The device operates at a frequency of 868 MHz with frequency-hopping retuning technology and two-way communication, which ensures stable and secure transmission of commands. Built-in overheating protection and voltage monitoring make the relay a reliable and safe element of automation.

Advantages

FHSS technology and two-way communication protect against jamming and guarantee command delivery
Encryption of transmitted data eliminates unauthorized access to relay control
Voltage monitoring allows you to monitor the state of connected circuits in real time
Overheating protection prevents damage to the device and connected equipment
The tamper input records an attempt to open or remove the device and transmits a signal to the hub
Cloud update and auto-recovery after a firmware failure ensure uninterrupted operation

Applications

Control of electric locks and gates as part of a wireless security system
Remote switching on and off of lighting or sirens when an alarm is triggered
Integration into smart home systems for automatic load control
Industrial facilities where wireless control of actuators is required
Commercial facilities with the need for remote access control

Frequently asked questions

What is a tamper input in the context of a relay?

This is a housing-opening sensor — when an attempt is made to remove or open the device, it sends an alarm signal to the security hub, recording the tampering attempt.

Can the relay be used as a standalone device without a Dahua hub?

No, the relay is a component of the system and is controlled via a Dahua wireless security concentrator at a frequency of 868 MHz.

Are there any limitations on the power of the load controlled by the relay?

The load parameters are specified in the official Dahua documentation — be sure to check compliance before connecting, or contact SAT Solutions specialists.
