Beeping or buzzing noise

If your Lorex DVR is making a beeping or buzzing noise while recording video, it’s likely that the hard drive is running out of space. To fix this, power cycle the recorder or monitor. If this doesn’t fix the problem, try plugging in a different monitor or using an alternate cable output. Another option is to factory reset the recorder. This will erase all settings from the DVR software, as well as any corrupted data.

The noise may also be caused by the cooling fan in the Lorex DVR. If the fan is too tight or too loose, it may cause the buzzing or beeping noise. In addition, excessive dust buildup may cause the device to vibrate. Additionally, grinding noises can be caused by the hard disk.

Poor ventilation
