Network Camera NVR CCTV Kits
The functional mode of NVR technology application is relatively flexible and can meet the functional requirements of today's video monitoring system to a large extent. The small NVR scheme with NVR technology as the core has the advantages of small scale, flexible operation, convenient use, economy and practicality. Its front end mainly supports 8-way 720P high-definition video image access with high-definition video camera, and then realizes the centralized management and real-time storage of high-definition video image information through NVR technology. In addition, this small NVR scheme can also support remote management of video images, preview analysis of video images, real-time upload of gigabit network interface video image data, local preview, video playback and other functions. The small NVR high-definition video scheme has a high overall cost performance ratio, simple system and high operational flexibility. This small NVR high-definition video monitoring system is widely used in the centralized video monitoring field in small areas such as companies, factories, family villas, offices, shops, supermarkets, etc.
NVR technology has been widely promoted and applied in urban safe storage, national security and other engineering projects with its own advantages in many aspects. Driven by market and technology, NVR technology will become the mainstream technology in the field of urban security high-definition video surveillance, with very strong theoretical research and practical application prospects

On the basis of the secondary network structure, a large NVR high-definition video system is built by converging into the primary network through private networks, optical networks, and public service networks. The storage and forwarding services of the primary network are realized through the industrial control NVR, and the redundant and safe backup of the video monitoring system is realized at the same time. This distributed multi-level coordinated back-end centralized management network mode greatly provides the overall function and fault tolerance of the video monitoring system, highlights the ease of operation and reliability of the high-definition video monitoring system based on NVR technology, and meets the flexibility, multi-function performance, sharing Emergency handling and other functional requirements.
High quality and high yield cultivation of pepper
Afforestation can be done through live planting or direct seeding. It's best to plant seedlings during spring and winter, especially when pepper sprouts begin to emerge in spring. Before and after the winter season, to prevent freezing damage, trees can be cut back and replanted, with their trunks buried and then allowed to thaw naturally in the following spring. Live seeding is typically carried out in early autumn, coinciding with harvest time. Pits with a diameter of 70 cm and a depth of 50–60 cm should be dug in advance, and the soil should be leveled before planting. About 8–10 seeds are placed in each hole, covered with about 1 cm of soil. Seedlings usually appear in the spring of the following year. During summer, especially on rainy days, seedlings can also be planted. When planting, it's important to select sunny or semi-sunny slopes in the lower part of the hillside, where sandy loam soil is ideal for optimal growth.
After planting peppers, weeding should be done 2–3 times a year, and timely irrigation is necessary during dry periods. Since pepper roots are shallow, weeds and other plants compete heavily for nutrients. As the saying goes, "If you don’t weed, the peppers will grow old." After the fruiting period, proper soil and water management is essential. In areas where irrigation is limited, fertilization becomes crucial for maintaining high and stable yields. Pig manure is considered the best organic fertilizer. After 10–15 years of tree growth, ring trenching should be applied, with approximately 25 kg of manure per tree. Additionally, intercropping peppers with legumes and green manure crops can improve soil quality and increase overall income.
To protect the fruit, specific measures should be taken during critical growth stages. Peppers generally begin budding in late March, flower in mid-April, reach full bloom in early May, and start withering in mid-May. If proper management is not maintained during this time, many flowers and fruits may drop. To help preserve the fruit, the following practices are recommended: 1) spray 10 mg/kg gibberellin during the flowering stage; 2) apply a solution of 0.3% phosphoric acid, 0.5% potassium dihydrogen phosphate, and 0.3% urea solution at both the flowering and mid-flowering stages; 3) after spraying, repeat the application of 0.3% potassium dihydrogen phosphate and 0.7% urea solution every 10 days. These steps can significantly improve fruit retention and yield.
