After the female worms are drilled into the skin of the pig, they will lay eggs in the epidermal tunnel, hatching the larvae and parasitizing the insects in the epidermis. Itching of the inflammatory rash caused by the stimulation of the saliva and metabolites of the female wax.

Installation and use should be relatively simple, mainly reflected in two aspects: one is that the installation and debugging of the camera itself should be relatively simple, and the other is that the operation of the client should be relatively easy to get started. Regarding the installation location and height, we have chosen a height of about 3 meters as a suitable installation location. This not only ensures good visibility, but also prevents the camera from being easily damaged by people
Bad.
3. To support multiple recording storage modes, not only local storage but also cloud storage should be supported.
Four. In the process of purchasing cameras, it is best not to be greedy for cheap prices and not simply pursue cheap prices. It is necessary to comprehensively consider factors such as the stability and clarity of the camera head. Whether the operation of the camera head is stable is determined by the 40 modules in the middle
The clarity is determined by the image sensor.
5. Because the 40 surveillance camera belongs to an all-in-one machine, the product structure is relatively simple, and there are no complex circuits, so it is very stable during use
