Setting up the BlackVue DR490-2CH

The BlackVue DR490-2CH does not have a WiFi app, screen, or buttons. In order to set up this device, you have to take the memory card out and put it into your computer. You can put the card in using a micro SD to SD adapter or USB card reader. To access the settings, you will need the dedicated BlackVue viewing software, available for download here.

BlackVue SD Card Viewer

Once you put the Micro SD card in your computer and open the BlackVue program you should see a list of video files populate. If it hasn't populated your memory card, hit the three dot option icon (indicated by the red arrow in the picture below), and locate your DR490-2CH card in the file explorer. When it is populated, you can access the settings by clicking the gear icon/settings button.

Basic Setting

When you click the settings button, you'll see two tabs. Click the firmware tab to change your dash cam settings. The basic settings should be configured before you start using your dash cam. Note that you need to power on the camera with the card inserted before you can access these settings as the viewer is modifying a file on the card. Here you can set your time, image quality, and other recording settings. If you do not have the optional GPS, choose the manual time setting and set the time. Make sure to offset the time to when you plan on plugging the card in and powering your device. For example, if it will take 5 minutes between setting your time in the desktop application to going back to your car and powering the camera on, set your time 5 minutes forward. This is because the time will not move forward while it is saved on the card.

Next there are the image quality settings. The default uses the highest image quality settings which records at approximately 22 Megabits per second combined for the front and rear channels. If you only have a 16GB or 32GB card, you may want to set this lower as it will start overwriting quite quickly at the highest settings. The other video settings (night vision, brightness, and saturation) let you fine tune the picture to your personal preferences.

The record settings affect the basic functions of the dash cam. You can turn normal recording off so that your camera will only record in parking mode and when impacts are detected while driving. You can also turn off parking mode, in which case your camera will record non-stop in parking mode if constant power is supplied, rather than using motion detection. Voice recording turns the mic on or off, this can also be configured on the camera by clicking the button on the right side of the device.

Sensitivity Settings

The sensitivity settings will affect the G-sensor (impact sensor) and motion detection sensor. If you are only using the camera in driving mode, you only need to adjust the first slider which is the normal mode G-sensor sensitivity. If you find that you are getting a lot of false events while you're driving, you should turn this setting down. We find that the default setting is quite high for most passenger cars.

The parking mode G-sensor setting is considerably more sensitive than the driving/normal mode setting as it needs to pick up very small impacts (e.g., parking lot speed bumps). The motion detection setting is referring to movements detected in parking mode that do not involve an impact. This could be cars driving by, trees blowing in the wind, pedestrians, etc. We find the default setting works reasonably well.

System Settings

The security LED setting refers to the white blinking light underneath the front camera lens. You can turn this on and off in the system settings tab. You can also configure the speaker volume and fully mute the speaker if desired. The settings for volume range from 0 to 3. You can also configure the memory card partitioning here. The event (g-sensor triggered) and parking (motion detection) folders can be increased/decreased in increments of 5%. The normal (driving mode) folder size will adjust automatically as the other two folders are changed in size.

Final Remarks

Once you've gone through all of these settings, make sure to hit the save and close button at the bottom of the settings pop up window. Take the card to your camera and power the camera on. After all the new settings have applied, you should format your memory card by holding down the button on the right side of the device. If you need to do a firmware update, you should do this before changing the settings as the settings menu may be slightly different from firmware to firmware.
