This phenomenon arises when the LED fluorescent lamp and the camera frequency bandwidth are the same.
It is called flicker. To address this issue,
it is recommended to replace the current camera with a varifocal lens camera.

1) If the recorder is equipped with an Embedded Linux operating system,
it is necessary to install the Ext FS program on Windows. After installation, you can use the program to check the video files.
2) When connecting a 3TB or larger HDD, make sure to connect to the SATA port, not a USB external disk.
3) When connecting an HDD to a Windows PC using a USB external disk, only HDDs with a capacity of 2TB or less are supported.

Event log data can be stored for an extended period due to its small size and separate storage from recorded data.
If the 5M camera is not connected,
go to Menu > Settings > System > Operation Method > Camera Resolution Settings.
Cause 1) The 5M camera is not connected.
Solution 1) [Menu]-[Settings]-[System]-[Operation Method]-[Camera Resolution Settings]
1) Connect the speaker to the monitor (with speaker control) + HDMI + NVR (audio OUT port (RCE))
=> Go to Smartphone > Speech Function > Two-way Function Control.
2) Connect the speaker to the monitor (without speaker control; Connect a microphone to the microphone jack) + HDMI + NVR

Typically, when outputting through HDMI, an SDI to HDMI converter adjusts the output to 60 fps.
1) Connecting an RCA cable and a DC power cable may result in the occurrence of rainbow noise.
(It is normal for the coaxial cable and the power cable to be connected together.)
Cables such as TVI and AHD cannot be connected. / Impedance matching is not possible, leaving no viable solution.
(It is recommended to use the minimum recommended specification video, power cables, a 75 ohm composite cable and a 5C cable.)
(In the case of ktt, it is advised to use a composite cable with a length of approximately 70 meters.)
2) Rainbow noise image (The result of using a 1-meter connecting cable / image displaying tailing and rainbow noise.)
1) Menu > Settings > System > Upgrade/Logo Backup > Save
2) The file format is JPEG (D1/ 720*480). / BMP format for default firmware file.
1) This product has obtained the KC certification. It poses no harm to the human body.
2) Electromagnetic waves are classified based on their frequencies (the number of waves per second) into various types,
such as radio waves (long wave, medium wave, short wave, ultra-short wave, microwave), infrared rays, visible rays (light),
ultraviolet rays, x-rays, and gamma rays. These types are arranged in order of increasing frequency. For example, radio waves have frequencies
below 3000 GHz, equivalent to three trillion vibrations per second.
(Sunlight, infrared rays, and ultraviolet rays also represent additional examples of electromagnetic waves.)
This product is equipped with a lightning protection sensor.
(It offers enhanced surge protection.)
