The principle of capacitive type sensor is to use positive and negative probes filled with liquid medium to form a linear change with the liquid level, the change of capacitance (that is, the change of liquid level) into a standard electrical signal output. The core components of the product use highly integrated special capacitance measurement chip, through accurate temperature compensation and linear correction, with high precision, high stability and continuous measurement advantages, with a strong independence. We provide customers several capacitive oil level sensors to meet your needs. You can choose one product according your medium, range, output signal and etc. We also provide OEM services, you can get your suitable products if you have special requirements of the products.

Video surveillance is usually installed for a variety of purposes. For some schools, the main purpose of video surveillance systems is to protect collective property from loss of property; while some schools are more focused on protecting students' personal safety, so that parents can be assured of their children's every move in school. For the nursery, you can also use the video to monitor the recorded images to show your parents to the Internet. The difference between monitoring targets and focuss directly determines the user's attention to real-time video and access to recorded video content. If you value Internet access, you need to pay special attention to whether the screen resolution can be optimized as needed.
2. Do you already have a VCR-based tape camera?
If you already have a tape system, you can take advantage of your existing camera and cabling system, which will save you a lot of unnecessary expenses. However, you should also take this opportunity to revisit the number of cameras you are using and where they are deployed. In addition, it depends on whether you install the video surveillance system yourself or install it through integration. If you install it yourself, you need to know the structure and wiring of the house. Do you know the basic wiring and location of the camera deployment? If you are not using an IP network, you will need a coaxial cable for installation. Even if you don't use an IP camera, you need someone with a network technology to help you watch and record video content online. If you plan to adopt an integrator solution, have they had success stories similar to your environment? The video surveillance installations shown in these success stories are usually maintained for a long time.
3. What are the strengths of the vendors, and are they rich in reference support?
4. Who is responsible for providing technical support for the video surveillance system?
Who provides technical support for your existing IT environment? If you have this kind of support, using a PC computer system will be even more handy. Some vendors also provide technical support.
5. What is the type of infrastructure being monitored?
Do schools have multiple buildings to be monitored? Are they geographically dispersed? If you have multiple buildings, do you want to centrally monitor targets in different locations? If you want to centrally monitor targets in all locations, you also have to consider the type of connection between the targets. The type and location of the infrastructure also affects where the camera is deployed. If the camera is deployed outside the building, then the building itself needs a special security system. If you want to make the camera adjust the monitoring angle, you need to purchase a PTZ-enabled camera (PanTiltZoom).
6. What type of network connection is between buildings and buildings?
There are many schools that have fiber optic networks installed between buildings or inside buildings. If this is the case, you might consider using an IP camera or a hybrid IP camera and a traditional analog camera. Although IP cameras are much more expensive than traditional analog cameras, the overall cost is still superior.
The IP camera does not require additional wiring and can be easily installed only by a network administrator. In addition, the price of IP cameras will gradually fall back. If you already have an analog camera, but want to use an IP camera, then you can consider building a hybrid system that supports both cameras.
7. What are your requirements for picture quality?
Different video surveillance systems can support different resolutions and frames. Resolution is a reference standard for measuring picture quality, and the higher the resolution, the higher the quality. Frames per second (fps) describes the number of frames (pictures) captured in one second. The higher the fps, the more consistent the recorded picture will be. High frame rates are often used to monitor attention-grabbing video, such as casinos, which use high frame rates.
8. How long do you want to keep the recordings?
High resolution and high frame rates require more network bandwidth resources and take up more video storage space. How long do you want to keep the recorded content? Your system provider or integrator will tell you the approximate requirements for resolution and frame rate, and will tell you how many days the video storage will remain. To some extent, this has a lot to do with the type of system being purchased. If you use a PC system, you can usually upgrade to get more video storage space.
9. What type of company is the video surveillance system manufacturer?
Whether you are installing a video surveillance system yourself or using an integrated system, you should be concerned with the actual manufacturer of the system. How long does it take for these manufacturers to work in this field? What type of support can they provide? Many vendors are located in Asia and the support they provide is not very rich. To set up a video surveillance system for the school, even though they are consulted about the school application.
10. What is your budget?
After answering these questions, it's time to get back to understanding system costs and your own budget issues. How much is your budget? Whether to contact a local system integrator or search for a video surveillance manufacturer online. Inquire from different manufacturers and compare the differences of their products according to their own requirements. It should be noted that this is not only related to the purchase, but also to the installation and maintenance issues after the product and system.
After reading these ten questions, you are aware of the choice of video surveillance system. But the factors that determine the purchase of a video surveillance system are complex, and they are also highly prone to waste. The school budget is usually not enough. When choosing a video surveillance system, it takes time to save money on these ten issues.
[ Huaqiang Security Network News ] It is understood that the video surveillance system is basically installed on the campus. It is conceivable that the school chooses a video surveillance system is a difficult task. Faced with numerous equipment vendors and solutions, you may feel helpless. The question you most want to know may be "Where should I start?" Maybe you already have an outdated VCR system or you are empty. In any case, you need to answer the following important questions before you choose a video surveillance system to help you make the right decision. Thinking carefully about these issues will help you reduce the high cost of making mistakes. According to the past experience of the industry, the following issues are particularly worthy of our consideration: 1. What is used after installing the video surveillance system?
