Smart Environmental Protection Requirements for Video Surveillance Products and Technologies

1. See further HD technology

At present, high-definition images have been widely used in industries such as transportation where high video quality is required. Pollution source monitoring involves the monitoring of small objects such as gas, particles, and suspended matter, as well as high-definition demand for images. In addition to high-resolution high-definition pixels, high-definition lasers and thermal imaging cameras that can be viewed for several kilometers, more than ten kilometers, and even farther away have more use requirements in water and air pollution monitoring.

2. See more transparent fog technology

Currently, there are two main types of video monitoring fogging technology, namely electronic fogging and optical fogging.

The thermal imaging temperature sensitivity of the three-band laser thermal imaging camera is up to 35mk. It has a higher sensitivity than conventional products, and can obtain finer picture quality and is less affected by fog, rain, and snow. It has a visible light fogging function, daytime optical filtering and DSP image processing to enhance image detail in mist, vapor, and dust environments.

3. More targeted video intelligence analysis

Video intelligent analysis technology is an important technology for video surveillance from passive to active, in which behavior analysis, face recognition, license plate recognition and other technologies have been widely used in public security, transportation and other industries.

In the monitoring of pollution sources, the analysis of the behaviors of the sewage outfalls, the regional intrusion of the sewage detection sampling points, etc. can effectively identify the behaviors such as artificial fraud, and there are many industrial intelligent analysis requirements:

(1) Smoke color identification: analysis and identification of the color of the smoke;

(2) Analysis of smoke blackness: judge blackness information of smoke;

(3) Water color analysis: Identify the color of the water body;

(4) Analysis of floating bodies of water: judging the quantity, density and other information of floating bodies in water;

(5) Smart Meter Reading: Data reading of environmental instrument by video.

4. Low power consumption, wireless transmission requirements

Most of the pollution sources are scattered and remote, and power supply and cable transmission are very difficult. At present, many sensors support wireless transmission, and since their own power consumption is very low, usually a battery can support several years of data acquisition. Compared with video capture devices, which generally consume more power, the design of a camera with lower power consumption can meet the demand for electricity, and at the same time it supports wireless transmission. The ability to selectively upload videos or pictures has become a demand for environmental video surveillance.

5. Corrosion-resistant, self-cleaning requirements

The source of pollution is often located in an environment with many water vapor, excessive dust and corrosive substances, and the protection of dust, water, and corrosion of the monitoring equipment must be taken into consideration. At the same time, it is necessary to monitor the self-cleaning function of the device such as the wiper, and it can be periodically or remotely controlled to perform self-cleaning to ensure the validity of the picture.

6. Video overlay and GIS map docking

The environmental protection business data is read over and overlaid on the corresponding video, and the real-time display on the map is realized through the combination with the GIS map, so that the presentation is more intuitive.
