TP-Link VIGI C340I 4MP Outdoor Bullet IP Camera, 2.8mm Wide-Angle Lens, PoE/12V DC, IR Night Vision 50m, Human & Vehicle Classification, H.265+, IP67, Built-in Microphone

The TP-Link VIGI C340I (2.8mm) is an outdoor IR bullet network camera designed for professional surveillance in business and commercial environments. It combines 4MP high-definition imaging, intelligent event detection, long-range infrared night vision, efficient video compression, and rugged outdoor durability. This camera is suited for locations that require consistent day-and-night monitoring such as shopfront exteriors, office entrances, warehouse perimeters, parking access points, loading zones, perimeter fences, and outdoor walkways—where both coverage and usable detail matter.

At the imaging core, the VIGI C340I uses a 1/3" progressive scan CMOS sensor and supports a maximum resolution of 4MP (2560 × 1440). This 2K+ level of detail improves clarity compared to standard 1080p cameras, helping you see finer scene information during live monitoring and in recorded playback. Higher pixel density can be especially useful in outdoor scenes with complex backgrounds, signage, and moving subjects, where additional detail improves practical identification and incident review. The camera supports multiple frame-rate selections up to 30 fps, giving flexibility to prioritize motion smoothness for active areas or optimize for storage depending on the installation.

This specific variant is equipped with a fixed 2.8mm lens with an F2.2 aperture, designed for wider coverage. The field of view for the 2.8mm lens is listed as H 88.8°, V 48.9°, D 106.5°, providing broad scene visibility that is well-suited for entrance zones, storefront approaches, small-to-medium parking sections, and general outdoor areas where you want more coverage per camera. Fixed-focus design keeps installation simple and stable. For planning guidance, DORI values for the 2.8mm lens are provided: Detect 60m, Observe 25m, Recognize 12m, Identify 6m. These values are intended as planning guidance and can vary with mounting height, camera angle, lighting, and real-world scene conditions.

For night-time and low-light monitoring, the VIGI C340I uses infrared illumination with two IR LEDs rated for up to 50 meters at 850nm wavelength. The camera includes an IR cut filter for day/night operation and supports unified, scheduled, or automatic day/night switching. Smart IR is included to reduce common night-surveillance issues such as close objects becoming overexposed or “washed out” under infrared light, while still maintaining visibility of subjects farther from the camera. This is especially important outdoors where reflective surfaces, walls, passing vehicles, and wet ground can create strong infrared reflections.

To support clearer imaging under challenging lighting, the camera includes image enhancement features such as DWDR (digital wide dynamic range) to help balance scenes with mixed brightness, and 3D DNR (3D digital noise reduction) to reduce noise and distortion in low-light conditions. It also supports common professional adjustments including backlight compensation (BLC), highlight compensation (HLC adjustable by client software), prevention of overexposure to infrared light, and rotation (90°/270°). Additional adjustable image settings include brightness, contrast, saturation, sharpness, exposure, WDR control, and white balance. For operational control and privacy compliance, it supports privacy masking (up to 4 masks), ROI (1 region), and OSD settings to label streams and manage what is captured or displayed.

For storage and bandwidth efficiency, the VIGI C340I supports modern compression formats. The main stream supports H.265+ / H.265 / H.264+ / H.264, and the sub-stream supports H.265 / H.264. H.265+ is designed to reduce bandwidth and storage usage compared to older methods, which is beneficial when recording continuously or deploying multiple cameras on the same network and NVR storage. Bit rate control supports CBR and VBR, allowing you to set a stable bandwidth target or let the camera allocate bitrate based on scene complexity. The video bit rate range is listed as 256 Kbps to 4 Mbps for the main stream and 64 Kbps to 512 Kbps for the sub-stream, enabling tuning for different network environments.

The camera supports flexible resolution options. For the main stream, supported resolutions include 2560 × 1440, 2304 × 1296, 2048 × 1280, 1920 × 1080, and 1280 × 720. For the sub-stream, supported resolutions include 640 × 480, 352 × 288, and 320 × 240. This dual-stream approach is practical in real deployments: you can record a higher-quality stream while using a lower-bandwidth stream for remote viewing and mobile monitoring.

Smart monitoring features help improve alert relevance and reduce unnecessary notifications. The VIGI C340I supports Human & Vehicle Classification and a wide set of smart events including intrusion detection, line-crossing detection, region entering detection, region exiting detection, object abandoned detection, object removal detection, abnormal sound detection, people detection, and vehicle detection. In addition to these smart events, it supports basic events such as motion detection, video tampering detection, and exception alerts (illegal login). Alerts and event handling support message push notifications, which can be used in compatible management environments to keep operators informed of important activity.

Audio monitoring is supported via a built-in microphone. The camera supports audio input and audio compression with an 8 kHz sampling rate, environmental noise filtering, and an audio bit rate of 64 Kbps using G.711 alaw. The built-in microphone is specified to record activity within approximately a 15-foot radius of the camera, which can provide useful context for entrances, staff access points, and other areas where sound helps validate events. This model does not list two-way audio (no built-in speaker output).

For networking and integration, the camera includes a 10/100 Mbps RJ45 Ethernet interface and supports ONVIF Profile S, enabling compatibility with many ONVIF-capable NVRs and video management systems, as well as TP-Link VIGI recording/management solutions. Supported protocols include TCP/IP, UDP, ICMP, HTTP, HTTPS, DHCP, DNS, RTSP, NTP, UPnP, SSL/TLS, FTP/SFTP, RTP, IPv4, IPv6, and ARP. Security features include password protection, HTTPS encryption, IP address filtering, and digest authentication. It also supports simultaneous live view of multiple streams (main and sub-stream combinations) and can be managed through supported client tools such as VIGI App, VIGI Security Manager, VIGI NVR, and a web interface.

For outdoor durability, the VIGI C340I is rated IP67 for weather protection against dust and water ingress. It operates within a temperature range of -30°C to 60°C and uses a plastic housing suitable for standard outdoor surveillance installations. Manual angle adjustment supports pan from 0° to 360°, tilt from 0° to 90°, and rotation from 0° to 360°, allowing installers to fine-tune framing on ceilings, walls, or poles depending on the site layout.

Power options support practical installation needs. The VIGI C340I supports PoE (802.3af/at, class 0) for single-cable power and data over Ethernet, and it also supports 12V DC input using a 5.5mm coaxial power plug. Power consumption is listed as a maximum of 5W on 12V DC, while PoE is listed as class 0. This flexibility helps in sites where PoE switching is available as well as locations where local DC power is preferred.

Overall, the TP-Link VIGI C340I (2.8mm) is a strong choice for businesses needing a wide-angle outdoor bullet IP camera with 4MP resolution, long-range IR night vision, smart human/vehicle detection, built-in audio monitoring, efficient H.265+ compression, and IP67 weatherproofing for reliable daily security operations.
