TP-Link VIGI C400HP-4 3MP Turret IP Camera, 4mm Lens, PoE, IR Night Vision, Smart Detection, H.265+

The TP-Link VIGI C400HP-4 is a professional 3MP turret network camera designed for reliable video surveillance in commercial and business environments. As part of TP-Link’s VIGI professional surveillance ecosystem, the C400HP-4 focuses on consistent image quality, intelligent detection, efficient compression, and flexible installation—without relying on version-specific hardware claims.

At its core, the VIGI C400HP-4 uses a progressive scan CMOS image sensor capable of delivering a maximum resolution of 3 megapixels (2304 × 1296). This resolution provides a strong balance between clarity and efficiency, making it suitable for monitoring entrances, corridors, retail spaces, offices, and general indoor or sheltered outdoor areas.

The camera is equipped with a 4mm fixed focal length lens with an F2.2 aperture, offering a more focused field of view than wide-angle lenses. This lens option is ideal for scenarios where mid-range detail and subject clarity are important, such as access points, aisles, or defined zones that require precise coverage.

For night-time operation, the VIGI C400HP-4 integrates infrared (IR) illumination with an effective range of up to 30 meters at an 850 nm wavelength. An IR cut filter enables automatic day/night switching, while Smart IR helps prevent overexposure of nearby objects and maintains visibility of subjects farther from the camera in low-light conditions.

Image quality is enhanced through digital image processing technologies including Digital Wide Dynamic Range (DWDR) and 3D Digital Noise Reduction (3D DNR). DWDR helps balance scenes with uneven lighting, while 3D DNR reduces noise and pixel distortion, particularly in low-light environments. Additional image controls such as Backlight Compensation (BLC), infrared overexposure prevention, and adjustable image parameters support stable and natural-looking video.

The VIGI C400HP-4 supports smart event detection to improve monitoring accuracy and reduce false alarms. Supported smart events include line-crossing detection and area intrusion detection, allowing users to define virtual boundaries and receive alerts when these boundaries are crossed. Basic events include motion detection, video tampering detection, and exception alerts such as illegal login attempts.

Video encoding is handled using efficient codecs including H.265+, H.265, H.264+, and H.264. H.265+ significantly reduces storage requirements and network bandwidth usage compared to older standards, making it suitable for continuous recording. Support for main stream and sub-stream encoding allows flexible configurations for recording and remote viewing.

The camera supports frame rates of up to 30 frames per second. Main-stream resolutions include 2304 × 1296, 2048 × 1280, 1920 × 1080, and 1280 × 720, while the sub-stream supports lower resolutions optimized for bandwidth-efficient monitoring.

From a networking perspective, the VIGI C400HP-4 features a 10/100 Mbps RJ45 Ethernet interface and ONVIF support, ensuring compatibility with TP-Link VIGI NVRs and third-party network video recorders. Supported protocols include TCP/IP, UDP, ICMP, HTTP, HTTPS, DHCP, DNS, RTSP, NTP, UPnP, and SSL/TLS, enabling seamless integration into existing IP surveillance networks.

Power options include Power over Ethernet (PoE) compliant with IEEE 802.3af/at (Class 0) or 12V DC input, providing flexible installation options. Power consumption remains low, supporting energy-efficient continuous operation.

Physically, the VIGI C400HP-4 features a compact turret-style housing with 3-axis adjustment (pan, tilt, and rotation) for precise positioning during installation. The camera operates reliably within a temperature range of -30°C to +60°C, making it suitable for demanding environments.

The TP-Link VIGI C400HP-4 (4mm) is an ideal choice for businesses seeking a 3MP IP turret camera with focused coverage, efficient compression, dependable night vision, and intelligent detection for professional surveillance applications.
