When you want to install a surveillance camera at home, the first thing you think of is to go to the e-commerce platform to buy it. But as soon as we opened the corresponding classification column, we were fascinated by thousands of camera products. For a while, we couldn't distinguish which surveillance camera products we really needed. Many users are not hesitant about the product, but really do not understand some professional knowledge of the surveillance industry. Therefore, the task of Suming.com today is to supplement some knowledge points related to cameras.
Avoid stepping on the pit guide 1: the relationship between resolution and pixels.
Pixels represent how many points there are in a certain scale. Resolution indicates how dense these pixels are. Whether the effect of the surveillance camera is high-definition is inseparable from the pixel size. The higher the pixel, the better the video effect. And the currently outstanding mega-high-definition camera is the mainstream home surveillance pixel. More than 200M, 300M, 500M is quite advanced monitoring equipment. When choosing a home monitor, you must look at the pixels. Compared with the pixels, the resolution is insignificant.
Avoid stepping on the pit guide 2: Master the basic camera indicators.
The first indicator: wireless or wired. The wireless camera itself transmits through WiFi or converts 4G to WiFi. Its original meaning does not mean no wires, but radio or wireless WiFi transmission. Wired is a surveillance camera that is powered by a network cable or provides tangible medium transmission through a network cable.
The second indicator: remote monitoring and direct recording. Direct recording means that it is stored locally in the memory card, and does not need to download the app software on the mobile phone for real-time monitoring. It only needs to read the video of the memory card through the card reader on the computer. Remote monitoring means that you need to download APP software on your mobile phone, the camera needs to be within the coverage of WiFi, and you need to know the WiFi account password. After the pairing is successful, you can directly receive the images transmitted by the video thousands of miles away with your mobile phone.
The third indicator: two-way intercom or one-way pickup. Two-way intercom generally means that the monitoring party can interact with the monitored party. One-way sound pick-up means that you can receive the voice of the other party through the mobile APP, and you cannot transmit the voice to the monitored person.
Guide to avoiding pitfalls 3: The perfect combination of price and function, high quality and low price exist.
Many users are worried that the camera function cannot meet the needs of various household scenarios, because buying high-priced surveillance cameras can avoid some defective products, but it is not necessary. Nowadays, there are various products of home surveillance cameras, but the functions are similar. Such as motion detection, night vision, pan-tilt rotation, cloud storage, human body sensing, etc., all of which can be reflected in surveillance cameras.
In summary, small home monitors are more advantageous than traditional large monitors. It does not take up space, does not need wiring to punch holes, and does not destroy the beauty of the entire environment.
