Equipped with a 4 MP high-resolution sensor, this fixed mini dome network camera delivers clear and detailed images, ensuring effective surveillance and security. The device features Acusense technology, which enhances its ability to accurately distinguish between human figures and other moving objects, reducing false alarms and improving alarm accuracy.

The camera includes a built-in microphone that captures audio, adding an additional layer of security by providing sound alongside visual footage. With a 2.8mm fixed lens, it offers a wide field of view, suitable for monitoring large areas.

Designed for durability, the camera boasts an IP66 weatherproof rating, making it resistant to dust and water, and suitable for outdoor environments. It supports both Wi-Fi and wired connectivity, allowing for flexible installation options and easy integration into existing networks.

The camera also supports H.265+ video compression technology, which significantly reduces bandwidth and storage requirements while maintaining high-quality video output. This feature ensures efficient data management and can help in lowering operational costs related to storage and bandwidth consumption.
