Although there are many reasons for the video surveillance system, it is certain that the video surveillance front-end equipment does have such problems during use. For security companies, it is necessary to explore and deal with the problem, but from another perspective, the existence of certain problems means more business opportunities. Is it possible to deal with problems with early detection of cameras through more comprehensive and proper services? Can companies that are engaged in system effectiveness evaluation win more market space? For example, from the product point of view, will the existence of such an unattainable camera stimulate the rapid market expansion of a new generation of products? These are left to the company with a lot of imagination. The problems with video surveillance front-end products can be summarized into the following categories:
1. Product quality problems include: the technical indicators of the product can not meet the calibration parameters, such as illuminance, clarity, environmental parameters, etc.; after a period of use, with dust, rain, high temperature, low temperature and other functions Decline, the technical performance of the product decays too fast; the sharpness of the image is not good enough, because the front end of most monitoring systems is still standard-definition cameras, D1 or CIF resolution images themselves are difficult to meet the needs in the application; DVR monitoring is used in large quantities. Analog cameras, the front-end signal is often interfered in the process of transmitting to the back end, resulting in image quality damage; the analog camera threshold is low, a large number of inferior machines are shoddy, and the images are mixed. In addition, the engineering is often too close, resulting in adverse effects on image quality in all aspects of the transmission process.
2, the problem of the product's later maintenance can not keep up is: the repair and parts after the problem has to wait for a long time, both imported and domestic equipment have such problems. The main reason for these problems is that the production process of the products is still relatively backward, lacking the necessary control means, and the quality of the components is not relevant. It can cause the camera to be blurred or completely invisible.
3, the system management flaws are mainly: whether it is analog monitoring system or DVR system, the front-end analog camera failure can not be reflected in time, resulting in a system may have many monitoring points have problems, and only after the call will see There is a problem with it. This in itself is a flaw in system management. In addition, due to the lack of standards, network cameras of various manufacturers mostly adopt special protocols and are not compatible with each other.
4, the problem caused by the price war of cottage products. First of all, many security enterprises in China lack the ability of independent innovation. The products of the cottage further catalyze the intensity of the price war, and at the same time make the homogenization of products intensify. Secondly, the quality link is weak, especially the sales structure maintained by the contact relationship, so that the quality of the product is often neglected. The quality of the selected material line is poor, which will lead to monitoring image interference. The quality of the components and structural parts will cause the cloud platform to be unmonitored. System control problems; without environmental testing, the front-end products will be damaged under high and low temperature environmental conditions.
In the face of problems with front-end products, are there more business opportunities for operation and maintenance services?
Coexistence of Opportunities and Pressures The single project with product operation and maintenance has low yields and needs to rely on large-scale services to make a profit. In the initial stage of business development, it is likely to cause the company to make ends meet. Therefore, at this stage, it is a big challenge for companies specializing in operation and maintenance.
Poly aluminium chloride (PAC) is a new type high efficiency inorganic polymer coagulant, adopting advanced manufacturing technique and quality raw material, show the features of low impurity, high molecula weight, and superior coagulating effect.
I. Poly Aluminium Chloride Properties
1. Its dosage lower than aluminum sulfate (based on Al2O3) and water treatment cost is lower than other inorganic flocculants.
2. The product can cause quick formation of flocs, big flocs formation and rapid precipitation. Its treatment capacity is 1.3-3.0 times of other inorganic flocculants.
3. It enjoys wide-range adaptability for different-temperature source water and a good solubility.
4. It is slightly corrosive and easy for operation.
5. The liquid product is suitable for automatic dosing. Furthermore, it will not block pipes over long-time usage.

Description: |
Poly aluminium chloride (PAC) is a new type high efficiency inorganic polymer coagulant, adopting advanced manufacturing technique and quality raw material, show the features of low impurity, high molecula weight, and superior coagulating effect.
Different grades of Polyaluminum Chlorides (PAC). The highly charged Al in the products is optimized for best performance for the different basicities of PAC. The low to medium basicity products are effective coagulants for treatment of both drinking water and waste water. And the medium to high basicity products are excellent for all ranges of wastewater treatment. |
III. Poly Aluminium Chloride Application:
1. Its purifying effect on low-temperature, low-turbidity and heavily organic-polluted raw water is much better than other organic flocculant, furthermore, the treatment cost is lowered by 20%-80%.
2. It can lead to quick formation of flocculant (especially at low temperature) with big size and rapid precipitation service life of cellular filter of sedimentation basin.
3. It can adapt to a wide range of pH value (5−9), and can reduce the pH value and basicity after processing.
4. The dosage is smaller than that of other flocculants. It has wide adaptability to the waters at different temperatures and at different regions.
5. Higher basicity, lower corrosive, easy for operation, and long-term use of non-occlusion.
