Top specs

  • Type

    NVR

    Recorder that uses IP cameras and network connection for video recording and management.

  • Number of Channels

    The maximum number of cameras that can be connected to and managed by the recorder

  • Resolution

    4K

    The highest resolution available on the market (also known as 8 Megapixels). It offers 4 times more detail than Full HD. This is cinematic quality that allows for maximum possible zoom to recognize critical details, even from a great distance.

  • HDD Slots

    The number of internal hard drives (SATA) that can be installed simultaneously in the recorder.

  • Maximum Capacity per Disk

    The maximum size (in TB - Terabytes) of the hard drive that the device "recognizes" and supports in each slot.

  • ONVIF

    ONVIF is a protocol that allows cameras and recorders from different manufacturers to communicate with each other.

  • Ports

    HDMI

    The digital output for video and audio. It is the standard way to connect the recorder to a modern TV or monitor (PC) and view your cameras in high resolution.

    USB

    Its main use is to connect a mouse for menu navigation and settings. Additionally, it is used to connect a USB stick (flash drive) in order to export (take a backup of) specific video clips that interest you.

  • Video Compression

    H.265+

    Smart version of H.265, designed for 4K/8K surveillance. It offers very low bandwidth in static scenes, combining high image quality with significant storage space savings.

    • The standard supports approximately 50–60 days of continuous recording on a 2TB hard drive 

    (Values and durations are indicative and based on standard settings. Actual performance may vary depending on resolution, frame rate, scene movement, and hardware.)
