The Tiandy TC-C321N 1CNB-4 is a compact bullet network camera for economical security monitoring. It combines Full HD video, a 4mm lens, infrared night vision, audio recording, PoE and weather-resistant protection.
For buyers searching for the Tiandy TC-C321N 1CNB-4 price in Bangladesh, the Touch IT price is ৳2,450. This 2MP IP camera records 1920 × 1080 video at up to 30fps and includes 30m Smart IR, a microphone, S+265, ONVIF and IP67 protection. Confirm availability and compatibility before ordering.
This fixed bullet IP camera provides essential image, audio and outdoor features. Its 4mm view suits gates, corridors and shop fronts where focused coverage is preferable to an ultra-wide scene.
The 1/3-inch CMOS sensor delivers 1920 × 1080 video. The main stream reaches 25fps in PAL or 30fps in NTSC at 1080p and 720p. A separate sub-stream can reduce remote-viewing bandwidth.
The M12-mounted 4mm F2.0 lens provides a 73.5° horizontal, 40.8° vertical and 84.2° diagonal field of view. Tiandy lists DORI distances of 59.26m detection, 23.52m observation, 11.85m recognition and 5.93m identification under suitable conditions. Explore the Tiandy IP camera range for wider lenses or higher resolutions.
Two 850nm infrared LEDs illuminate scenes up to 30 metres. Smart IR helps control illumination on nearby subjects, while the automatic IR-cut filter changes between colour daytime and black-and-white night modes. Minimum illumination is 0.02 lux in colour and 0 lux with IR operating.
The integrated microphone adds sound to footage around entrances, counters and loading points. G.711A and G.711U are supported. No speaker is listed, so the camera does not provide two-way talk by itself.
Tiandy S+265, H.265 and H.264 options help manage network bandwidth and NVR storage. DWDR, BLC, HLC, 3D digital noise reduction, defog, automatic gain and adjustable white balance improve visibility in varied conditions. Motion detection and four privacy-mask areas support practical monitoring within a configured CCTV surveillance system.
IEEE 802.3af PoE carries power and data through one Ethernet cable, helping simplify installation. ONVIF Profiles S and T, SDK, CGI and Milestone compatibility support integration with suitable recorders or software. IP67 sealing, 4kV surge protection and operation from -30°C to 60°C suit exposed locations when properly installed.
