As the saying goes, "Everything grows on the sun." This means that sunlight is the most basic condition for all flowers to survive, grow and develop. Most flowers need light, but different types of flowers have different requirements for light intensity and length of sunshine. Usually people divide sunlight into direct light and scattered light. The light that shines directly on the sunny day is called "direct light," and the cloudy or shaded light is called "scattered light." The intensity of light and the length of time have a great influence on flowers. For example, rose flowers, pomegranates, half-branches, lotuses, water lilies, etc. that need to grow in the sun, if placed in a shaded environment, branches often appear slender, internodes are elongated, and the leaves are yellow, and are also susceptible to Insect and pest attacks; hi-yin flowers refer to the flowers that originally grew in the shade of hills or under the forest. In the summer heat season, shades need to be given in different shades. At the same time, the air humidity must be properly increased to ensure safe summers such as orchids. , Monstera, evergreen, jade and so on. The length of sunshine has a great influence on some flowers. Some flowers originate in the tropics. Only in short days (with daily light limited to 8 to 10 hours) can the buds bloom, such as poinsettia and leaves. Flowers, etc., if artificial shading treatment, reduce the sunshine duration, can promote early flowering. Temperature is very important for the growth and development of flowers. Due to the different climates of the country of origin, the various flowers have different requirements for temperature. In winter, flowers with high temperature and high temperature will suffer freezing injury in low temperature environment; flowers with low temperature and high temperature will not be able to sleep and consume large amounts of nutrients, which will affect normal flowering results. Hi-temperature (daytime temperature is 20°C to 25°C, no less than 10°C at night) Flowers, Commonly cultivated Euphorbia pulcherrima, Dogtail red, Malvaceae hibiscus, Annonaceae hawk The African wind fairy of the Faerieaceae, the wind-colored pear, the water tower flower of Pyracaceae, and the colorful leaf grass of the Lamiaceae. Hi-temperature (temperature is generally maintained at about 18°C) Flower, commonly cultivated with white orchids of Magnoliaceae, jasmine flowers of Oleaceae, Cyclamens of Primulaaceae, Primula, Begonia, Begonia, Begonia, Asteraceae The cineraria, the Milanese of the Polygonaceae, the two-colored jasmine of the Solanaceae, the clivia of the Amaryllidaceae, the Manjusri, the Amaryllis, etc. Hi temperature (daytime temperature in winter is maintained at about 15 °C, no less than 5 °C at night) flowers, common cultivation of Camellia, rhododendron, osmanthus, orchids, rubber trees, cycads and citrus plants. In short, the cultivation of flowers must first understand their ecological habits, hi light or hi Yin, requiring high temperature, medium temperature or low temperature, otherwise it is difficult to maintain their favorite flowers.

Do you want to add a monitoring card to your computer, or do you want to use an embedded hard disk recorder as your monitoring host. The computer monitoring card is more suitable for places that are familiar with computer installation, have professional personnel on duty, and have more functional requirements. Its overall investment is relatively low. Since the monitoring card is installed in the computer, the computer needs to be started 24 hours a day; As for the latter, it does not require professional knowledge, nor does it need to be on duty, and it is relatively simple to operate.

To install security monitoring equipment, it is necessary to determine how many cameras are installed, and the quality and monitoring range of the cameras are affected. It is preferred to determine how many cameras are used for monitoring, and then determine the camera lens monitoring range according to how many cameras are available. Therefore, the distance from the camera to the monitoring point and the monitoring area must be clear. The infrared supply network recommends using the camera of 480 TV line, because it is more in line with that definition.
When installing security monitoring equipment, the third consideration is whether the camera has night vision function. If the monitoring is installed in a dark place, it is necessary to consider using a camera with infrared night vision function.
The security monitoring equipment can be installed via wired or wireless transmission. Although the cost of wireless network is relatively high, it can save a lot of installation trouble and make the monitoring site more beautiful. However, the installation of wireless network monitoring equipment should take into account the environmental problems of security sites. Cement building materials will shorten the wireless transmission distance, and metal building materials may complete the shielding of wireless signals. The infrared transmitter and infrared receiver should be far away from other appliances to avoid interference. Because the price of wireless network is almost twice that of wired transmission monitoring equipment, I suggest using wired transmission installation.
On site monitoring and network monitoring When determining the installation of the monitoring system, you should consider whether you need network functions. That is, if you need to monitor and control the monitoring site on the Internet at any time, you need to select a monitoring host with network functions. Avoid no network transmission function after installation.
A complete security monitoring equipment should at least have three parts: surveillance camera, PTZ and decoder. The following are their installation methods:
