|1. (WO2018196350) VIDEO RECORDER BASED ON RJ INTERFACES|
|Applicants:||SHENZHEN UTEPO TECH CO., LTD
|Title:||VIDEO RECORDER BASED ON RJ INTERFACES|
The present invention belongs to the technical field of video recording devices. Provided is a video recorder based on RJ interfaces, the video recorder comprising a power supply circuit, a coding circuit, a video and power supply integrated circuit and a plurality of RJ interfaces, wherein the video and power supply integrated circuit comprises a video signal receiving end, a power supply anode output end, and a power supply cathode output end; each of the RJ interfaces comprises a pin 1, a pin 2, a pin 3, a pin 4, a pin 5, a pin 6, a pin 7 and a pin 8; the pin 1 and the pin 2 are respectively connected to the video signal receiving end; the pin 3, the pin 4 and the pin 5 of the RJ interface are connected to the power supply cathode output end as a power supply cathode; and the pin 6, the pin 7 and the pin 8 of the RJ interface are connected to the power supply anode output end as a power supply anode. Thus, network video signal transmission and power supply are realized by means of one network cable, thereby solving the problems of difficulty in power supply at a camera end, inconvenient installation on site, and an increase in costs caused by erecting two sets of lines at the same time.
