Hikvision infrared waterproof dome camera camera evaluation

Hikvision DS-2CS58A1P-IRS infrared waterproof dome camera, there are two major advantages, first, the structure is exquisite, easy to install and maintain; and its near 700TVL quality effects, so that the image is more realistic and delicate. Without too many fancy and cumbersome, it is designed for the car environment, giving a simple but not simple sense of benefit.

The DS-2CS58A1P-IRS dome camera is a 960H solution. It uses a 1/3 "DIS sensor, effective pixels are 976 (horizontal) × 496 (vertical), comes standard with 3.6mm lens, in addition to 2.8mm, 6mm lens can be selected.

Firstly, the camera is aligned with the sharpness test card under full zoom at the lowest zoom. After careful observation, the real-time horizontal resolution of the camera is approximately 660--680 TVL. Then replaced with 24 ** color restore test card, and then compared to the test card and the camera processing image effects, intuitive sense of color reproduction is basically accurate.

Then we performed a white balance detection on the camera. Under a warm lighting environment of about 4000K, the color reproduction of the aircraft was accurate. In the cold light source environment of about 6500K, although the color gradations were easily recognizable, they were slightly blueish. .

How about the transmission speed? After the tester aimed the camera at the stopwatch, the stopwatch and its image (via DVR processing and real-time forwarding) were simultaneously captured by the SLR. After calculation, the 960H image was quickly transmitted and controlled at about 120ms.

The difference between the Hikvision DS-2CS58A1P-IRS dome camera and most dome cameras is that the body is very thin, the shell is made of aluminum alloy die-casting, streamlined shape, exquisite touch, and compact; and it adopts a close-closed design. The protection level is IP66, so that the camera is not easily eroded by dust and water vapor. The design of the base is also very special. The side is high and the side is low. The lens is located close to the low side. This design allows the camera to obtain a wider viewing angle in the vehicle environment.

Open the cover, you can see the lens has been glued fixed in order to prevent vibration in the vehicle environment affect the lens defocus; but you can manually rotate the three-dimensional steering shaft to adjust the camera's perspective. Around the lens is a circle of LED infrared light, even if the lightless environment, but also to achieve a clear monitoring. In addition, you can customize the camera settings through the OSD control buttons on the structure board.

Observe its lead line again, adopt the aviation head that is not easy to loose, support DVR power supply and video signal output; In addition, the camera also has built-in pickups, the audio picked up by this combination cable is also transmitted, to facilitate the system wiring .

In a normal light scene, the camera image is observed. In addition to being realistic, the image of the dynamic object is quite smooth.

Then simulate the bus door monitoring scene to test, when the digital wide dynamic function is turned off, because the background is bright, although the indoor foreground target has a sense of hierarchy, but the picture is slightly dark; then in the same environment, open the wide dynamic function, The brightness of the indoor foreground image has been greatly improved, and the wide dynamic effect has a certain rendering effect.

Then simulate the light change environment for testing. The DS-2CS58A1P-IRS supports auto/color/black-and-white/intelligent switching modes. This time it is detected in automatic mode. In the process of declining illumination in the test environment, it can be found that the machine's automatic gain effect is good, and the brightness and saturation of the image can be automatically adjusted to the optimal state and the response is very fast; when the illumination is about 3 Lux, It was found that the camera automatically switched to black and white mode and infrared light was turned on. The effective monitoring distance of the machine's infrared light is 15-20 meters, and the distance of the on-site simulation is 1-6 meters. Within this distance we find that the black-and-white image is clear, clean and noise-free, and the infrared light control is also good, making the image No signs of overexposure. The machine's intelligent infrared adjustment function can automatically adjust the power according to the distance of the shooting object, and always ensure that the image is not exposed.

Finally, enter the OSD menu and set digital noise reduction to off. At this point, more snowflakes appear on the screen. When selecting “level”, although the image quality is improved a lot, the image is still noisy; only when the digital noise is reduced Under the “high” level, the screen is still clean and tidy when no light is ensured.

After the above tests, we have learned about the basic situation of this car camera. Overall, this is a simple, practical, and easy to install and maintain 960H camera program, which has a clear image, color accuracy, night vision function Good features, in addition to motion detection, image mirroring and other optional features.

Expert Comments: Hikvision's 960H car camera has a special appearance, exquisite structural design, and excellent image quality to make the image clear and delicate. No matter if the appearance, clear picture quality, or dust and waterproof performance, this camera is compared. Suitable for car applications.
