Onvif, the absolute standard for IP cameras. Being Onvif guarantees compatibility with any modern recording system. NOT being Onvif, means having a camera that is an end in itself and can never be used together with recording systems. |

The advantage of a PoE camera is clear, it can be powered with the same cable with which it communicates without carrying 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 the optimized implementation of H.265 codec that uses 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 you need to work in high light/shadow contrast conditions. It is essential when shooting from inside to outside, license plates, shadowed areas or any situation where there is no homogeneity of light. ![]() |

BLC (Back Light Compensation): 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 fair adaptation to these situations. ![]() |

This camera has ROI function. Images from IP cameras are “compressed”, so the quality is set during recording. Especially on cameras with very high resolution, it is often necessary to reduce the quality in order to ensure a reduced bandwidth occupation and record a greater number of days or cameras. The ROI allows you to define areas where you can 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 definition of the image. ![]() |
