Comparison

The 2 MP (1920×1080) Hikvision DS-2CD3025FHWD-I IP camera (6 mm) is designed taking into account the difficult conditions of round-the—clock and year-round outdoor operation: housing protection from moisture and dust meets the requirements of the IP67 standard, operating temperature range -40 °C... +60 °C, IR illumination range - 40 m — The backlight is made using EXIR technology: a powerful, energy-efficient diode does not create much noise, and a rectangular diffusing lens protects against blurring light outside the stage, illuminating the center of the frame and darkening the edges.

The DS-2CD3025FHWD-I (6 mm) is based on a highly sensitive (0.005 lux at F/1.2) CMOS sensor measuring 1/2.8 inches, which forms a color image even when the stage is illuminated only by street lights - the automation does not switch the camera to black and white mode for longer.

Functionality

WDR 120 dB is a hardware function that creates two frames with different shutter speeds and then summarizes them into one, balanced in brightness.
BLC — compensation of the back light.
3D DNR is a three—dimensional noise reduction.
ROI is the area of interest: the function leaves the maximum resolution in the selected area, and reduces it in the rest of the frame, helping to focus on the desired area and optimizing the bitrate. A ROI region is provided for each stream

Video codecs are provided for compression, including modern H.264, H.265 and the so-called smart codecs H.264+ and H.265+, to reduce the load on the network and server — 3-streaming, to increase the information content of the video sequence due to smooth playback — the broadcast speed of the main stream is 50 fps. The camera's analytical functions include detecting faces, line crossings, intrusions, abandoned and missing objects.

Basic parameters, optics, interfaces

The camera comes with a fixed 6 mm (52°, F/1.6) lens, supports day/night mode with ICR: in sufficient light, the filter refracts IR rays, improving color reproduction, and in the dark it mechanically shifts away from the matrix to increase sensor sensitivity and backlight operation.

On-board interfaces include an RJ-45 network port, an SD card slot with a capacity of up to 128 GB. Metal case. A swivel bracket is included to simplify the adjustment of the monitoring direction. The power supply is 12 V DC, PoE. The power consumption at peak loads is 6.5 watts. Size — Ø70×155.03 mm, weight — 410 g.
