The TP-Link InSight S345-4G is an outdoor turret network camera operating at 4 MP resolution, providing 24/7 full-color video recording thanks to its integrated spotlights and 4 mm fixed-focus lens. The device is equipped with a 4G LTE modem and three LAN ports, enabling operation in locations lacking standard network infrastructure and allowing for the wired connection of additional devices directly to the camera. The system utilizes AI algorithms for precise classification of humans and vehicles and offers an active defense function by generating sound and light signals upon event detection. The design integrates a speaker and microphone for two-way audio transmission and includes a microSD card slot for local data archiving. The camera meets IP66 weatherproofing standards, supports efficient H.265+ compression, and is powered by 12V DC.

3 LAN Ports for Easy Deployment
The InSight S345-4G camera offers 3 LAN ports, making it possible to connect up to 3 additional devices. This is an ideal solution for connecting to a solar power system to eliminate the need for additional cabling.

Human and Vehicle Classification
Distinguish humans and vehicles from other objects to receive more accurate event notifications.

LightPro Night Vision Technology
VIGI LightPro technology intelligently switches between infrared night vision and full-color night vision based on human or vehicle detection. This allows the camera to record clearer, more detailed images with white light illumination when needed, while reducing light pollution and energy consumption by using infrared light for most scenarios.
When no vehicle or human is being monitored, only infrared night vision is active.


When a vehicle or human is detected, full-color night vision is activated.
Once the vehicle or human leaves the field of view, the camera switches back to infrared night vision.

Smart Video Enhancement Technologies
- True WDR: Analyzes and combines different exposures so that both bright and dark areas are correctly exposed, ensuring a balanced and natural image even in high-contrast lighting environments.
- Smart IR: Dynamically adjusts infrared illumination to prevent overexposure and glare, increasing visibility at various distances for a clearer image.
- 3D DNR: Noise reduction technology that analyzes image data from multiple frames to selectively reduce noise while preserving important details.
- White Balance: Ensures neutral white tones in the image, regardless of lighting conditions.
Efficient H.265+ Compression Technology
H.265+ lowers bandwidth requirements and storage space while maintaining excellent image quality. It allows for savings of up to 57.5% and 15% in storage space compared to H.264 and H.265, respectively.
