Onvif, the absolute standard for IP cameras. Being Onvif guarantees compatibility with any modern recording system. NOT being Onvif means having a stand-alone camera that can never be used with recording systems. |

The advantage of a PoE camera is clear, it allows it to be powered with the same cable with which it communicates without running additional power cables and without having to install a separate power system, a PoE camera guarantees constant voltages and simple installation. |

Smart H.265+ Smart H.265+ is an optimized implementation of the H.265 codec that uses a scene-adaptive coding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure, and intelligent noise reduction to deliver high-quality video without straining the network. Smart H.265+ greatly reduces bit rate and storage requirements compared to standard H.265 compression |

ULTRA WDR up to 120dB WDR (Wide Dynamic Range): This is the professional solution when working in high-contrast light/shadow conditions. It's essential when shooting from inside to outside, license plates, shadowed areas, or any situation where there's uneven lighting. ![]() |

BLC (Back Light Compensation): it is one of the 3 possible steps in the management of images with contrast, typical situations are: entrances or exits from parking lots, license plates, particular lights, entrances with shots from the inside towards the outside, etc. Light compensation is one of the most complex operations possible, the BLC function allows a reasonable adaptation to these situations. ![]() |

This camera has ROI function. Images from IP cameras are compressed, so the quality is set during recording. Especially with very high-resolution cameras, it's often necessary to reduce the quality to ensure less bandwidth usage and record a greater number of days or cameras. The ROI allows you to define areas where you want to set a higher quality (for example, a door, the area where the license plate usually passes, an exit, etc.). In that area, I can set a higher quality , thus ensuring a higher image definition. ![]() |
