Câmara de vigilância Tenda K4W-3TC com fios e sem fios 4 canais

The Tenda K4W-3TC Surveillance Camera kit combines wired and wireless connectivity in a four-channel system designed for home and small-business security. The kit uses 2.4 GHz Wi‑Fi (802.11b/g/n) and wired Ethernet options to simplify installation and expansion without extensive cabling. Cameras provide up to 3MP (2304×1296) HD video for clearer detail, support motion detection with AI‑based person recognition, and include dual spotlights plus dual infrared lights for color-capable night monitoring. The NVR auto-discovers and pairs cameras to streamline setup, and the system supports remote viewing and alarm push notifications via the TDSEE mobile app.

Advantages

The hybrid wired & wireless design removes the need to run Ethernet cables for every camera while keeping wired options available for fixed installations. An independent router-level Wi‑Fi chip with dual high‑gain antennas and Tenda wireless transmission technology extends coverage (up to 200 m open range) and improves through‑wall performance. Automatic camera search and pairing eliminate complicated manual network configuration. AI‑based motion detection reduces false alarms by distinguishing human targets from non‑human movement. Dual spotlights and IR lights together with sensitive image sensors provide full‑color or grayscale night modes, and audible plus flashing light alarms deter intruders while sending alerts to your phone.

Suitable for

• Home perimeter and entrance monitoring
• Small office and retail store surveillance
• Outdoor coverage where running cables is difficult
• Locations requiring remote live view and push alerts

How to use

Place and mount the cameras in desired locations, connect the NVR to power and your local network (wired or via Wi‑Fi). Power on the system and allow the NVR to automatically search for and add the cameras; no manual networking steps are required for pairing. Configure recording schedule, motion sensitivity, and night‑vision mode through the NVR interface or TDSEE mobile app. Use the app to view live streams, playback recordings, and receive alarm notifications.

Recommendations

Install cameras at recommended heights and angles to cover entry points and approaches; keep the router or NVR centrally located for optimal wireless coverage. For best night‑time color imaging, enable spotlights or use Full‑color Mode. Regularly check the TDSEE app and adjust motion detection sensitivity to balance detection accuracy and false alarms.
