Anti-freezing measures for plants and flowers: Bitao, plum blossom, waxy plum, loquat, magnolia, etc., can be used straw, wheat straw, rags, old cotton and other warmth to protect the warmth of stem culms. It is also possible to coat white flowers and trees over the winter, not only effectively preventing freezing damage, but also preventing and controlling diseases and insect pests that remain on branches. However, it should be noted that with the whitening agent formulated with quicklime, quicklime must be converted to hydrated lime before use, otherwise it will burn flowers and trees branches. The formulation ratio of whitening agent: 36-40 parts of water, 10-20 parts of quicklime, 1-2 parts of table salt, 2 parts of clay, and 2 parts of lime sulfur stock solution. Quickly dissolve the lime and salt, mix with lime sulfur and clay. Stir well and whiten. It is advisable to whiten the dose to prevent it from flowing down.
In winter, some of the more hardy flowers and bonsai can be allowed to outdoor winter in nature, but do not ignore the cold and warmth of these flowers and trees.
Cold-resistant herbal flowers antifreeze measures: cineraria, pansy, kale, glutinous rice, etc., in case of severe cold or rain and snow, can be covered with plastic film, warm grass and other warm objects, until the weather is clear and then opened To make the seedlings dwarf.
Antifreeze measures for bulbous flowers: Canna flower bulbs, dahlias and other bulbous flowers need to be used for underground wintering outside. They can be covered with compost soil, rot leaves, and subtilis. Pay attention to make bulbs below the frozen soil layer, otherwise they will freeze the bulbs. Can not sprout new buds. Note that the cover must not contain pathogenic eggs.
More cold-resistant potted plant antifreeze measures: The best method is to even bury the pot below the outdoor permafrost, so that the root system from frost damage; can also be used to cover the basin surface ash, not only the insulation effect is good, but no adverse effects on flowers and trees. In those years, cuttings of flowers and plants survived. Because of their small size and poor resistance to cold, in addition to allowing the main branches and leaves to receive sunlight, the remaining branches should be covered and covered with warmth, and some of the potted soil should be covered with plant ash or other insulation to keep warm.

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
