The first thing you need to do is to have the authorization from the school to watch the real-time monitoring from your home computer, and the second thing you need to do is to be able to meet the information transmission of the remote monitoring on the equipment.
To realize the specific operation of remote real-time video monitoring:
Analog camera + video card (computer)
This way in the first few years used more, because the price is more affordable. Usually with a free domain name resolution service. Now rarely used, the main reason is that the compression rate is not high, can not do real-time, and higher bandwidth requirements, coupled with the impact of new products in recent years and lost the price advantage. You also need a computer for hosting.
Analog camera + hard disk recorder (DVR)
This way is still a lot of people in the use of, because it is compared with the first way no longer need a computer to do monitoring host. And easy to store. Especially for monitoring points more concentrated stores, factories and other small-scale monitoring system.
Analog camera + network video server (DVS)
DVS is a new generation of network video coding equipment, its better network adaptability and centralized management capabilities to get the market sought after. Especially large-scale monitoring system projects, such as safe city, large-scale factories, neighborhoods and so on. Compared to DVR, the only shortcoming is that a single device can support the number of cameras less than DVR.
Internet camera (IPcamera) is a new surveillance camera in the past two years.
Network cameras are completely free from the analog monitoring of the boundaries, with good scalability, centralized management capabilities, low construction costs and other advantages. And the network camera can also be transmitted in the WIFI wireless network. It is the most popular remote monitoring equipment in the current market. Suitable for any place. Especially the remote management of branch offices, family caretakers and so on. However, in some more centralized small monitoring places, its price is less competitive. I believe that as the market and technology matures, it will unify the monitoring market.
