"Five Looks" identifies cows pregnant
Looking at the iris above the pupil of the cow's eye, there are three particularly prominent erect vessels on the iris, the so-called gestational blood vessels, which fill the surface of the iris and appear purple-red. The blood vessels on the iris that are not pregnant are small and not visible. Look at the breasts of the breasts, the nipples are straight, and they are pregnant cows. The breast does not swell, and the nipple is not stiff and there is no pregnancy. Look at the mouth and open the cow's mouth, look at the sublingual meat on both sides of the mouth. If it is bright red, it is a pregnant cow. If it is pink or reddish, the cow is not pregnant. When the tail of the tail cow is drooping, if it covers the vulva and tilts to the left or right, the cow is pregnant. If the tail is covered vertically, it means there is no pregnancy. Look at the milk milk that is squeezed out by hand. It is honey-colored and paste-like. It is mostly pregnant cows. If it is white and thin, and it will naturally flow out, it will be empty cows.

The IOT card of the video surveillance camera needs to be stable enough to keep the flow normal during use without being stopped. After using the IOT network card with defective quality for a period of time, traffic theft or other abnormal conditions suddenly occur, resulting in card suspension, which makes the camera terminal unable to use normally, and may have a significant impact on the business. Generally speaking, video monitoring is event driven or abnormal images (some intelligent algorithms need to be supported) to generate high traffic usage. For example, monitor video playback or live broadcast via 4G/5G remote viewing. Generally, the daily standby traffic consumption is M, and the common definition of video viewing is about hundreds of M an hour.
