IP security camera Foscam S41-W (Bullet, 4 MP, 2560×1440, 2.8 mm, IP66, Wi‑Fi & Ethernet)

Foscam S41-W is a bullet IP security camera with a 4 MP CMOS sensor and a maximum resolution of 2560×1440 at 25 fps. The camera supports both wired (Fast Ethernet) and wireless (IEEE 802.11ac) connections, uses H.265 video compression, records locally to microSD cards up to 128 GB, and provides two‑way audio via built‑in microphone and speaker. Designed for outdoor use with IP66 protection, it includes IR night vision up to 10 m, a 2.8 mm fixed lens with a 121° horizontal field of view, a built‑in siren and WPA2 security. Power is supplied by 12 V DC, 1 A.

Advantages

The camera combines wired and wireless connectivity options for flexible installation, efficient H.265 compression for reduced storage and bandwidth usage, and local microSD recording for standalone operation. IP66 rating and IR LEDs ensure reliable outdoor performance and night monitoring, while two‑way audio and an integrated siren enable direct communication and alerting from the device.

Suitable for

• Outdoor perimeter monitoring for homes and small businesses
• Entrance, driveway and backyard surveillance
• Locations requiring local recording on microSD
• Situations needing two‑way audio or audible alerts

How to use

Mount the bullet camera on a wall or ceiling using appropriate hardware for the chosen surface, orienting the 2.8 mm lens to cover the intended area. Connect power using a 12 V DC, 1 A supply and attach an Ethernet cable for wired network operation or configure Wi‑Fi (IEEE 802.11ac) with WPA2 security for wireless use. Insert a compatible microSD card (up to 128 GB) for local recording if required. Use the camera’s web interface or supported mobile app to set resolution, frame rate, H.265 encoding, motion and audio detection, and to enable the integrated siren. A reset button is available for restoring factory settings if needed.

Usage recommendations

Install the camera under a sheltered position when possible to reduce direct exposure to extreme weather despite its IP66 rating; format and test the microSD card before relying on local recordings, and secure Wi‑Fi with WPA2 and a strong password to protect the device and streams.
