The rapid development of infrastructure has accelerated the continuous improvement of surveillance camera technology. From new social demands such as Smart Safe City, Xueliang Project and Skynet Project, we can know that surveillance is the most important part of security. According to ‘Research And Markets’, the global video surveillance camera market size was USD 21.82 billion in 2018 and is expected to grow at a CAGR of 8.7% during the forecast period 2019-2027, reaching USD 45.93 billion by 2027.Due to the particularity of the camera's PoE power supply solution and it can save the complicated drilling and wiring, which is beneficial and harmless in terms of engineering cost and project cycle.

For the PoE technology industry, the market prospect of PoE power supply solution for cameras is promising. PoE power supply equipment includes PoE power supply, PoE switch, PoE splitter, PoE extender and other supporting equipment. The main function is to provide power and network data transmission for surveillance cameras. The commonly used connection methods for PoE power supply of cameras are:

1.PoE power supply

The PoE power supply solution is no need for extra power cords, and a network camera only needs one network cable to supply power and network, but the network cable must be unshielded category 5e twisted pair or above and there is no problem in power and network data transmission within 100 meters. PROCET camera PoE power supply equipment conforms to IEEE802.3AF/AT standard, the maximum output power of a single port is 30W, and the gigabit data transmission rate connection scheme is shown in the figure below.

2.Ultra-long distance PoE power supply

The upper limit of the transmission distance of the ordinary PoE power supply solution is within 100 meters. When the monitoring construction exceeds this range, the optical fiber PoE power supply solution should be considered. Optical fiber PoE transmission distance (5Km~50Km) can meet the long-distance, multi-device and several monitoring networking requirements, or the high-speed network transmission requirements of remote networking control, suitable for campus network, enterprise optical fiber LAN or broadband access in large residential quarters network solutions.PROCET Fiber PoE power supply complies with IEEE802.3bt and PoE++ standards. Fiber optic transmission data signal transmission is stable and anti-interference, which solves the characteristics of long-distance, high-speed, and high-bandwidth Gigabit Ethernet and Fast Ethernet work group users. The fiber optic PoE power supply connection scheme is detailed in the figure below.
