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.

    PoE

    These ports allow you to connect IP cameras directly to the recorder. The camera receives power and transmits video through the same network cable, making installation extremely simple (plug-and-play).

    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

    Advanced codec with approximately 50% better compression than H.264 for the same quality. Ideal for 4K and 8K content, supports HDR and UHD, significantly reducing the required bandwidth.

    • The standard supports approximately 30–35 days of continuous recording on a 2TB hard drive

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