Points to note when buying a camera

[ Huaqiang Security Network News ] I am a project manager. We have a very good answer to the problem of buying a video camera. Each has its own characteristics, but most of them teach you how to choose a camera from a technical point of view. How big is the lens selection, how to distinguish between true and false CCD, the distance quality of infrared light, etc., all of them are profound, the dizziness of various parameters is very reasonable, including the video surveillance section in the SS community. some. But how much help we have when we are working on a project to make a choice of cameras, let alone how much water is there in the parameters, we don't know. Even if it is a genuine parameter, the basis for making a camera selection decision relative to a project is not the camera's parameters. In fact, the role of these parameter functions does not require much research. Today, the SS community talks about how to choose a camera from the perspective of the manager from the perspective of project operation.
Purchase camera
The first step is to make a budget, how much the monitoring system accounts for, and how much the camera has to account for.
The ultimate goal of our project negotiation business is to talk about the final profit of the contract. Will we be entangled in one parameter when we negotiate the joint project? ? Besides, now, as long as you have requirements, the manufacturer will be very happy to cooperate with you to change the model. It is specially designed for this model to print the manual and certificate, and to mark the various parameters that people are satisfied with. Therefore, the first element of the project is price. This price can't be too low, nor too high. If you feel low, you can't do it well. If you don't meet the budget of others, it won't work. Therefore, we have to have a bottom in our own mind, how much budget to use for the monitoring system, and what price to buy for each camera.
The second step is to select the camera brand of the appropriate grade and do the brand finalist work.
Only under the premise of the first step, we will take the budget amount and then choose the camera to be able to make a reasonable offer and increase the chance of success. After getting this budget, we started to find manufacturers that are more in line with this price. If it is an engineering firm, many manufacturers will send you information. Slightly filter and find more suitable manufacturers, if it is Party A or middleman. So, look directly at the engineering firm to cooperate, and it is worthwhile to make a little profit. Then send the approximate requirements and the required quantity of the project to the manufacturer, let them choose the model by parameter, and then report the price. If necessary, you can ask the manufacturer to send the machine to test. Anyway, no matter what parameters, it must meet the customer or The requirements of your design, such as the number of meters to see the clear license plate, the clear picture that must be seen at night, how far to see the details and so on. After the quotations are sent, sum up and review the budget, remove the non-conforming budget, and leave several manufacturers to start the next step. In this step, we have to leave a certain amount of space in the budget, so as to avoid changes in the function implementation that lead to exceeding the budget. Or you can leave it, because the manufacturer's first offer can't give you the actual price, leaving room for you to bargain, so this bargaining space can also be used as a budget space.
The third step, bargaining
At this time, the design information and cost accounting of the project should almost come out. It is time to do deepening design work. The specific functional requirements are not satisfied with this model. If the parameters are too low, choose a better camera and exceed the budget. It is cheaper to cut the parameters of the camera. In short, this process is the stage of constant communication between the manufacturer and Party A. The purpose is to achieve the function and achieve the expected profit on the books. Which camera can achieve the function, the profit can be maximized, and which model is used to make a quotation. Of course, this depends on the quality of the after-sales of the manufacturer and the wishes of the customers. However, the manufacturers operating in a grade are similar in this respect. How much money to buy? It is difficult to find a way to cross this grade. Something to come.
The fourth step is to summarize the grades of the manufacturers in order to prepare for the next cooperation.
The project started to work, and when we got the goods, we can see the effect of the real thing. Because I had previously found the same grade manufacturer's quotation, I believe that the price belongs to the same grade. If the price is similar, the effect is not good, then the camera of this manufacturer will be removed from this grade. For manufacturers with relatively good results, they can be upgraded to a higher level. Larger projects can also be found for him. The effect is achieved again, but the price is lower than a grade, so that your offer will be more competitive, profit. It will be even higher. Through this means, we will continue to explore excellent cooperation projects with manufacturers to form a supply chain that strongly supports our own business, so that the future projects will be more smooth.
Ok, let's talk about it for the time being. More things need to be experienced and summed up in the actual operation process. This article I deliberately published in the SS community's engineering management board, because it is not a technical article, nor how to choose the camera from the technical parameters.
In addition to the camera, the same is true for other devices. Welcome everyone to add a discussion.
