Frequently Asked Questions

How does a dash cam with parking mode work?

A dash cam with parking mode is designed to record any movement or impact that occurs while your car is parked. The dash cam will automatically turn on when it detects motion or vibration and begin recording. This feature is useful for monitoring your car while it is parked and can provide evidence in case of a hit-and-run or theft.

What is the recording time of a dash camera?

The recording time of a dash camera depends on the size of its memory card and the video resolution. Generally, a 64GB memory card can record up to 10 hours of footage at 1080p resolution. However, if you use a higher resolution or have a smaller memory card, the recording time will be less.

How can I tell if my dash cam is recording?

Most dash cams have a recording indicator light that will turn on when the camera is recording. You can also check the memory card to see if it has any video files saved on it. Additionally, some dash cams have a voice prompt that will let you know when recording has started or stopped.

How does a front and rear dash cam work?

A front and rear dash cam has two separate cameras that record footage from the front and rear of your car. The cameras are connected by a cable and the footage is usually displayed on a split screen. This type of dash cam is useful for capturing footage of accidents or incidents that occur behind your car.

What are the power options for a dash cam?

Most dash cams can be powered by the car’s cigarette lighter or USB port. Some dash cams also have a built-in battery that can provide power for a short period of time. However, using the battery can drain it quickly and is not recommended for long-term use.

Do you need WiFi for a dash cam?

Without WiFi, dash cam footage can only be accessed by removing the SD card and transferring the files to a computer. This process can be time-consuming and inconvenient. With WiFi, drivers can quickly and easily access their footage from their smartphone, making it more convenient to view and share video clips.

Do Dashcams record audio inside car?

Many dash cams have the capability to record audio inside the car, providing additional context to the recorded footage. However, audio recording is typically inactive when the car is turned off, unless the dash cam has a separate power source.

Why are Dashcams low quality?

Dash cams typically have lower quality than phone cameras because they are designed to capture video footage of the road and surroundings while driving, rather than high-quality photos or videos. To keep costs low and ensure reliable performance, dash cams often use lower-quality sensors and lenses than smartphones.

Is it worth installing Dashcam?

There are several reasons why drivers opt for dash cams, ranging from security and legal protection to capturing memories or unusual events. Some of the key benefits include: Providing first-hand evidence in the event of a car accident. Preventing insurance fraud, such as ‘crash for cash’ scams.

Can I leave my dash cam on overnight?

Leaving your dash cam connected to the cigarette lighter overnight is generally safe, as long as the camera has a built-in voltage monitor that will shut off the camera if the battery voltage drops too low.

Do Dashcams record at night?

Dash cams are designed to record your drives, day or night, continuously. However, when driving during the evenings, or in areas where there’s no sufficient light, such as tunnels or underground parking lots, your dash cam footage may look dark and grainy, making details difficult to see.

How does a dashcam get power?

Some dash cams come with a built-in battery, while others require a constant power source. You can power your dash cam using your vehicle’s cigarette lighter or USB port, or by hardwiring it directly to your car’s electrical system.

Is 128GB enough for dash cam?

A 128GB SD card can record up to 8 hours of footage in a dash cam, which is twice as much as a 64GB SD card. This means you can go longer periods of time without having to download and clear your footage.
