Top specs

  • Type

    DVR

    Recorder that works with analog cameras, converting their signal to digital for storage.

  • Number of Channels

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

  • Resolution

    Full HD

    It offers a sharp, clear image (2 Megapixels), allowing you to distinguish details, such as faces or objects, with clarity.

  • Incoming Bandwidth

    This is the actual processing power of the recorder. It determines how much "load" (data) it can handle simultaneously from all cameras. A high number is necessary for many channels at high 4K resolution.


    • Example 1: You have 4 cameras of 5MP (each requiring ~8 Mbps). A total of ~32 Mbps is required. An NVR with 80 Mbps Incoming Bandwidth is more than enough.
    • Example 2: You have 16 cameras of 4K (each requiring ~12 Mbps). A total of ~192 Mbps is required. An NVR with 160 Mbps is not enough and will "lose" cameras or reduce their quality. Here, you need an NVR with at least 256 Mbps.

    40

  • 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

    VGA

    An analog video output. Used to connect the recorder to older computer monitors.

    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

    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.)
