Well done on your wise decision to purchase a dash cam, here at RMJ we understand that it can be a daunting task. Don’t worry RMJ we will help you through it, we can assure we stock the best quality camera’s to meet your needs. Before we dive into the more technical specifications, let’s take a look at some of the options you should consider when selecting a dash cam that’s right for you.

Your Budget

We have a camera for every budget, but how much should you really spend?? This will depend on what’s important to you. While all our cameras offer excellent footage, the lower end units may lack build quality or functions that more expensive units provide. So it’s vital to figure out what it is your really after, for example if you don’t need a touch screen or Wi-Fi compatibility, why pay for it?

Camera Size

Size does matter when it comes to dash cams. Small, discreet cameras work best if you’re concerned about your valuable investment being stolen and have less impact on your view when driving. These are important points, but smaller cameras come with less features, and often require add on devices such as GPS or devices.  Larger cameras also provide screens too, which can help when playing back footage or adjusting menu settings easier, these can also be hidden comfortably behind your rear-view mirror so they don’t get in the way.

Video Quality and Resolution

When we talk resolution we are talking about the quality of video your camera can record. The higher the number, the better the quality.  If your top consideration in investing in a dash cam is to use the footage as evidence, it’s important to ensure you invest wisely in a camera that captures as much detail as possible. Almost all quality dash cams record in high definition (HD) but these levels vary from 720p,1080p and now even 1296p. Don’t worry about the numbers, just remember the higher the better!

Dual-lens front and rear cameras

If protecting your vehicle from every angle possible is important to you, then you should definitely consider dual-lens options. The front camera usually acts as the main unit, managing power, image processing and memory, this means you can have a smaller rear units. These units are often connected by a long cable which is neatly routed through your vehicle. Dual-lens camera units come with excellent software allowing you to flick through captured front and rear footage. This gives you piece of mind that the camera is working hard to capture everything in its view.

Memory Capacity

The dash cams sold on RMJ record their own footage onto a Micro SD memory card which slides into a small slot found externally on the device. Whilst all these cards are small in size they vary in capacity. The higher the capacity the more it can store. Memory cards can accumulate files that are protected in case of an incident. These short clips often are saved and unless deleted will take up space. We would therefore recommend a larger capacity memory card, this will make it easier to manage.

GPS Maps and Speed

GPS (Global positioning system) allows your dashcam to monitor your location, and uses this information to plot your route on a map when you view your footage using the software provided with your camera. Vital information such as speed can be also be captured.  This function can be disabled if required.

Low-light Performance

Dashcams rely on there being a source of light in order for them to record useable video and some perform better in low-light situations than others. All cameras will capture useful footage if you're driving in areas with good street-lighting, but if you spend a lot of your time driving at night then you should consider a camera with a wide dynamic range (WDR). This is sometimes referred to as a high dynamic range (HDR) but both terms refer to the cameras ability to process data effectively in low-light conditions and digitally enhance the footage to deliver improved results

Parking Protection

If you've even returned to your car to find it damaged, and the culprit long gone, then parking protection will be of interest to you. In this mode, your dashcam will use motion detection technology to monitor activity around your vehicle and record a short clip if it detects any significant movement. It will also start to record if it feels a bump or knock using it's internal g-sensor and start to record. In both cases, your car camera could well capture footage of the guilty party which can help you to track them down.

Event Recording and G-Sensors

All the dashcams we sell include internal g-sensors which measure movement up,down,left ad right, forwards and backwards. Using this information, the camera can identify sudden or severe movement, such as swerving erratically, slamming on the breaks or in the worst case a significant collision and can protect the video being recorded at the that time from being overwritten.  You can also on most dashcams use the event record button should you wish to record and save a particular event you witnessed during your journey


Some of the top end units boast wifi connection so that you can sync your tablet or smartphone to review footage, adjust settings or watch a live feed to help you set up and align your camera.

When activated, your dashcam will produce its own Wi-Fi hotspot that you can connect to with your device.  As all brands differ with regards to their setups you will need to download specific mobile apps which will allow you to connect to your camera. Your wifi range is however limited to 5-10metres which is sufficient.

Suction or Adhesive Mount

The ideal position for you dashcam is affixed to your windscreen or behind your rear-view mirror. This is done by means of either a suction mount or a semi-permanent adhesive mount. They both have their pros and cons, while adhesive mounts are usually smaller and more compact, which can help to hide your camera, a suction mount will allow flexibility as it can be removed. Most dashcams can easily be removed from their mounts, which is an important consideration for the security conscious

Hardwiring Your Camera

A simple and easy way to connect your dashcam is via a cable to the cigarette lighter socket. However, you may prefer to hardwire their camera into the car electrics. This not only hides the cables on show but frees up the socket for other devices. When you hardwire the camera you can choose to wire it to a circuit which is powered all the time, meaning you can take advantage of the parking protection modes so the camera is always on and recording. Most dashcams can be wired to a car via an optional compatible hardwire kit. We always suggest using the services of a fully qualified, insured, and experienced auto electrician. It’s not a big job so shouldn’t take too long!
