Network Surveillance Camera Zyxel Aurora CAM3115 — 2.1 MP (720p/1080p), fixed focal, color day/night, audio, Wi‑Fi, Bluetooth 4.1, DC 5V, Alarm Extension Module

Zyxel Aurora CAM3115 is a network surveillance camera with a 2.1 MP image sensor that supports 720p and 1080p output modes and a fixed focal lens. The camera offers color day/night imaging and integrated audio for basic two-way or monitored sound. Wireless connectivity is provided via Wi‑Fi and Bluetooth 4.1, and power is supplied by a DC 5 V input. An Alarm Extension Module allows connection to external alarm devices for expanded monitoring scenarios. The design and feature set make the device suitable for residential and small-business security installations where simple setup and wireless operation are required.

Advantages

The camera combines a 2.1 MP sensor with selectable 720p or 1080p output, offering clear video capture while keeping bandwidth demands moderate. Color day/night imaging preserves color detail in daytime conditions and produces usable images in low light. Built-in audio enables audio monitoring and basic two-way communication. Wireless connectivity via Wi‑Fi and Bluetooth 4.1 simplifies deployment without running network cables, and DC 5 V power support is compatible with common low-voltage power supplies. The included Alarm Extension Module provides a practical way to integrate door sensors, sirens, or other alarm equipment into the surveillance setup.

Suitable for

• Home indoor monitoring of entrances, living areas and nurseries
• Small office or retail surveillance where wired networking is impractical
• Remote audio-monitored locations needing basic two-way communication
• Sites requiring external alarm integration such as door contacts or sirens

Position the fixed lens to cover the desired field of view and adjust camera mounting for stable framing.

Usage recommendations

For reliable wireless performance, place the camera where Wi‑Fi signal strength is strong and avoid installing near large metal objects or RF interference sources. Use 1080p when higher detail is required and 720p to reduce bandwidth and storage use. When integrating external alarms, verify voltage and wiring requirements of connected devices before making connections to the Alarm Extension Module. Regularly update camera firmware and change default access credentials to maintain security.
