Evolution of solar mobile surveillance lighting trailer technology over the years

1. Initial stage: Background of the birth of solar mobile surveillance lighting trailer

1.1 Limitations of traditional surveillance lighting equipment
Traditional surveillance lighting equipment mainly relies on mains power supply, which makes its deployment have many limitations. According to relevant statistics, in some remote areas or temporary places, due to the lack of stable power supply, the installation rate of traditional surveillance lighting equipment is less than 30%. In addition, the mobility of traditional equipment is poor, and once it is installed and fixed, it is difficult to flexibly adjust according to actual needs. Moreover, the maintenance cost of traditional equipment is high, and the average maintenance cost of each device is about 1,000 yuan per year, which is a considerable expense for large-scale deployment of surveillance lighting systems.
1.2 Initial application of solar energy technology
Solar energy, as a clean and renewable energy, has gradually been applied to the field of surveillance lighting since the end of the 20th century. Early solar mobile surveillance lighting trailers were mainly based on traditional trailers, with solar panels and simple energy storage devices installed. The conversion efficiency of the solar panels of these early devices was low, generally around 10%, resulting in insufficient endurance in continuous rainy weather, usually only lasting 3-5 days. However, the application of solar energy technology provides new possibilities for the mobility and independence of monitoring lighting equipment, enabling it to operate independently in areas without mains electricity supply, and preliminarily solves some limitations of traditional equipment.

2. Technical start: characteristics of early solar mobile monitoring lighting trailers

The capacity of the battery is also limited, usually only meeting the operation requirements of the equipment for 3 - 5 days in continuous rainy weather. The functions of the charge and discharge controller are relatively basic, and can only achieve simple overcharge protection and over-discharge protection, and cannot perform refined power management and optimization. Although this simple solar power supply system can provide basic power support for the equipment, it has obvious deficiencies in stability and endurance.
2.2 Basic mobile monitoring functions
The monitoring functions of early solar mobile monitoring lighting trailers were relatively basic. They were mainly equipped with low-resolution cameras, whose pixels were generally between hundreds of thousands and one million.
