Long Distance Transmission: With HD Videoloss technology, it supports transmissions up to 500m / 800m over separate RG59 / RG6 coaxial cables. Smart IR: The P series is designed with smart IR function to prevent overexposure of IR LEDs when objects / people approach the camera at night, thus ensuring that the light intensity changes in proportion to the distance between the camera and objects. 4-in-1 Advanced Technology: The P series has 4-in-1 advanced technology and built-in UTC chipset which can flexibly adjust HD analog signal output, such as AHD / TVI / CVI / CVBS. It's the ultimate solution for true plug-and-play that works seamlessly with any brand of HD analog DVR. Protection: With a precise and robust mechanical design, it is resistant to water and dust thanks to its IP67 industrial classification. Supports ± 30% input voltage tolerance, it can safely operate under extremely unstable power conditions. With a working temperature ranging from -30 ° C to +60 ° C, it performs well in a variety of harsh outdoor environments.
