Should I get a Single or a Dual Dash Cam?

A single lens car dash cam kit comes with the one camera to record what is happening in front of your vehicle.

A dual dash cam kit will have a front facing camera and a second camera that can be mounted to record what is happening behind the vehicle. In some cases the front and rear camera will be both attached to the body of the front camera, though we feel that it is best for a rear camera to sit at the back of the vehicle to better capture what is happening.

Alternatively the second camera can be used to record what it happening inside the vehicle. This setup where the second lens can recording inside the vehicle is common for taxi drivers and those working for Lyft and Uber. Which can be very helpful to make sure that the passengers are not misbehaving.

If you opt for a dual dash cam setup it’s important to consider the resolutions that both cameras can record at simultaneously. Our dual lens dash camera, the Proze Dual Dash Cam 4.0 will capture full HD 1080P resolution at the front and 720P at the rear simultaneously. Also take into account that when recording from two cameras at the same time you will use up space faster on the storage card. Because all our dash cameras have loop recording this isn’t too much of an issue but worth keeping in mind if you want to keep recordings of a scenic drive.

If you want to use the second camera to monitor what is happening inside the vehicle the rear camera on the Proze Dash Cam 4.0 has 4 LEDS surrounding the internal facing camera which ensures better night time recording inside the vehicle so it can still capture good quality recordings at night.

Video Resolution

You will want to make sure that your main camera is at least 1080p Full HD, as you will need this to get greater resolution and therefore clarity and detail in your recordings, so that you can actually make out details such as the car make, model and number plate.

All Proze Car Cameras are Full HD, with some newer and higher resolution models coming very soon. So you are sure to get the picture you need.

Display Screen

The majority of car DVR cameras will have rear facing screens. This makes it quick and easy to ensure alignment when installing the camera. This screen also lets you view recorded footage and photos easily at the side of the road and offers an easy interface with access to all the settings and parameters.

Dash cams without a screen will typically have a smartphone app that can pair with your iOS or Android device, this app typically allows access to all the settings as well as reviewing recordings and can also make it quick and easier to share video footage.  However if you do use a dash camera with a smartphone app ensure you have used the app to set up the camera before setting off.

So the camera can be recording without distracting you. On the Proze Dash Cam 4.0 there is also a screensaver, so you can turn off the screen and prevent it from causing distractions when driving. When using a phone app camera, make sure you DO NOT use the phone whilst driving and when using the Proze Dash Cam 4.0, remember it is also against the law to operate the camera whilst driving, so you must ensure everything is set up before setting off.

This is also why our cameras all have the safety feature of not allowing you to access the menu when recording and you have to stop recording to access the menu.

HDR / WDR

The purpose of WDR (Wide Dynamic Range) or HDR (High Dynamic Range) is essentially the same. They both aim to make the video clearer and minimise the impact of bright and dark light conditions. If you have high contrast between the light and dark areas of a recording or photo then this technology will help make them clearer. It manages this by taking multiple images at different exposures and balancing out the exposure to correct for under exposed or over exposed elements. This enhances the image making it easier to pick out details. WDR does this image processing through hardware while HDR achieves similar results through software.

Suction Cup or Adhesive Mount

A car DVR is normally mounted to the windshield with an adhesive pad or a suction cup mount. The adhesive pad mount is usually more compact and allows the dash camera to be mounted closer to the windshield which generally makes it less conspicuous than cameras using suction cup mounts. 

The second benefit of using an adhesive pad mount is that it forms a stronger bond and will typically hold the car camera in a more stable position so you get a smoother recording, especially when driving on bumpy road surfaces. Though once used, you will most likely need a second one if trying to remove and refit the camera elsewhere.

However the adhesive pads are also more difficult to move or remove and are great if permanently fixing your camera in place. Otherwise Suction Cups are more versatile, to move the camera and remove it if needed.

Additionally once removed there is very little evidence that the vehicle has had a dash camera installed in it.  With a suction cup mount you can use the dash cam on multiple vehicles easily switching it between them which is the main advantage. Also with a suction cup mount you can easily swivel the camera around to record a traffic stop interaction for example. This isn’t always as easy with an adhesive pad mount.

There is also a third type of dash camera setup that is attached over the rear view mirror on your vehicle. This normally fixes in place over the existing rearview mirror on your vehicle being help in place by some rubber straps. The main think to consider with these is what the size of the camera is and what the size of your mirror is. Some larger vehicles with bigger rearview mirrors may have large mirrors that overlap the rear view mirror dash camera.

Loop Recording

All Proze dashboard cameras have the loop recording feature, in fact you could argue that loop recording is what defines a dash camera. This is a standard feature that allows the device to make efficient use of the storage card for recording footage. Most dash cameras let you set the loop recording duration, usually 1, 3 or 5 minutes. This section of video is stored on the micro SD card of the product or on its internal storage if it has any.

Once the loop is completed the dash camera will record another section of video, usually the videos overlap a few frames. Once the storage card is full the dashboard camera will record over the earlier non protected video section. By recording video in small sections it’s easier to manage them and any important video loops can be manually protected at the touch of a button to prevent them being recorded over. (See manuals to learn which button serves this function whilst recording).

Also if you have set up a dual car camera system, then you will have the function recording at the back as well.

G-Sensor

A G-sensor is a built in accelerometer or gravity sensor chip. Normally the sensitive of this sensor can be adjusted from the settings menu. This sensor constantly monitors the state of the vehicle.

If a sudden movement is detected such as heavy breaking or swerving the car DVR will automatically protect the video recording that’s taking place at that time. This is to ensure that important footage, that may prove crucial in proving the cause of an incident on the road, isn’t lost or recorded over due to the loop recording function.

This also works when you have parking guard active, as the G sensor will activate is the car is knocked and wake the camera up and start recording. This feature is the one that you will want if you leave your car parked for long periods and want to keep it safe.

GPS

Some of the best dash camera kits include GPS (Global Positioning System). This system could be built into the device or possible into the windscreen mount. A GPS has the ability to record your location, direction and speed travel as well as keep track of where you have been.

This information can be particularly useful for professional drivers or for fleet vehicles where proving where you were at a certain time could be helpful for your job.  GPS software can be used on your computer to view the GPS data recorded from each journey and track deliveries, journey times and routes.

Parking Monitor / Parking Guard

The parking monitor function allows the device to protect your vehicle while it is parked. Usually utilising the G-sensor to detect any movement of the vehicle this function will detect if your vehicle has been knocked or been the target of a breaking or vandalism. Some dashboard cameras may also use motion detection to aid in this as well.

The Proze Dash Cameras all have both of these functions to allow for complete protection from parking guard.

If the parking monitor is triggered the dash camera will start recording for a predetermined duration which is intended to record the perpetrator of the incident, such as capturing the registration plate of a car that has bumped into you while manoeuvring in a car park or the person who has just knocked your car with a trolley.

The camera will normally have a small battery to facilitate this function but can also be hardwired into the cars electrics as well. We would recommend seeking the advice of a skilled motor electrician or garage before hard wiring your dashboard camera yourself.

Proze Dual Car Cameras contain a small battery to allow for this function and saving of any recorded files in the event of the G-Sensor / Parking Guard being activated.
