Description

The DAHUA wireless contact sensor is an advanced security device that serves as a key component of modern alarm systems. Its main task is to monitor the status of door and window openings, allowing for immediate detection of unauthorized entry attempts. What distinguishes this model from standard magnetic sensors is its built-in shock and vibration detector. Thanks to this, the device can react not only to opening itself but also to attempts at forced entry, such as hitting or drilling, which significantly increases the security level of the protected area.

Specification

Installation and configuration of the sensor are extremely simple and intuitive, thanks to full integration with the Dahua ecosystem and a dedicated mobile application. The device allows for remote firmware updates via the cloud (Cloud Update), ensuring that the system always uses the latest patches and functionalities. An additional advantage is the built-in temperature sensor, which allows for monitoring conditions inside the room in the range from -15°C to +65°C. The aesthetic, white housing with compact dimensions makes the contact sensor discreetly blend into any window frame or door jamb, maintaining a modern look while providing the highest protection.

The use of two-way radio communication in the 868 MHz band ensures a stable and reliable connection with the alarm panel over a distance of up to 1200 meters in an open area. The security of transmitted data is guaranteed by advanced AES128 encryption, which prevents signal interception by third parties. Additionally, the 'frequency hopping' function protects the system against intentional jamming attempts by automatically selecting the clearest transmission channel. The product is characterized by remarkable energy efficiency – a single CR123A battery allows for continuous operation of the device for approximately 3 years, and the user is informed about low battery levels in advance.
