Front And Rear Dash Cam (Best Multi Channel 2Ch & 3Ch Cameras)

dash cam radar detector combo Best Dual Dash Cam

One of the hot accessories people are adding to their car these days is a front and rear dash cam.

Camera rigs are cheap and you can buy one online for less than $50 with pretty good features.

The camera mount will attach to the windshield (front and rear), dashboard (front and rear), sun visor or rear view mirror.

Some dash cam rigs record the driver and the road simultaneously. I guess this works well for vloggers.

You can get a basic Dash Cam or one that is loaded with:

  • Full HD
  • Dual Cameras (front and rear)
  • G-Sensor
  • Infrared
  • microSD slot
  • Night Vision
  • Wide Angle
  • WiFi
  • Motion Detection
  • GPS
  • Phone Apps

And a lot more…

But don’t be too surprised if even the basic camera rig has more knobs and buttons than most people can figure out.

Hmm…

Can someone show me where the record button is?

The cameras are powered by plugging in directly to the 12v accessory jack, a rechargeable battery, and some have a capacitor.

Many cameras are also heat-resistant, which makes sense if you have your rig attached to a windshield in Phoenix.

I’m sure on a hot summer day, the basic camera would get cooked!

Why are people buying front and rear dash cams for their cars?

I think people are buying dash cameras for 5 reasons.

#1. For recording their trips with family while on vacation. You can actually find dashcam videos on YouTube. I saw a funny video of a dad driving in a rainstorm and scaring his kids.

A dash cam is definitely safer than using a cell phone camera to record with. I’m guilty of driving while shooting video with my cell phone. You can find the video here of me recording a monsoon storm.

A dash cam is definitely safer than using a cell phone camera to record with. I’m guilty of driving while shooting video with my cell phone. You can find the video here of me recording a monsoon storm. I don’t recommend using a cell phone to record videos while driving on the road. It is dangerous and those who do it increase their accident risk by 20%, according to a study by Carnegie Mellon University.

#2. For recording in case, they are in an accident. Somehow we all think we are better off if we have a video of the accident. But think twice because the video might also work against you.

I saw a video of a car accident where the guy sounded like he was clearly at fault. But in the end, it showed that because his car was blocking the view, no one could see who actually started the crash. Make sure to turn off your dashcam when you are involved in an accident just for this reason. It is really not helpful if you have a video of an accident you caused.

#3. In case we are pulled over by law enforcement. Unfortunately, recently there has been a rash of videos posted showing less than professional behavior by public servants (I’ll leave this one there).

So many people are thinking that having a video of their encounter with an officer will keep them safe.

This is actually the most dangerous reason to buy a dash cam because it makes you feel like you can fight or argue with law enforcement. Please don’t ever do this because there’s no way you will win against an armed police officer especially when he has no video to prove his side of the story.

I’m afraid that you might just be creating another video for YouTube. If you have a dashcam and are pulled over, turn it off.

#4. To use it as evidence in case they are accused of a hit-and-run accident. Or any sort of car accident where they want proof that they weren’t at fault. Unfortunately, so many people do this these days and they try to scare the other party into accepting liability. You can find a ton of videos where people try this and end up arguing in public and then either both parties get in an accident or one person is forced to accept fault when they really aren’t at fault. Pay attention to your memory cards and only use it when you need it because if you misuse it, it can become a problem.

#5. For security purposes. We want to record people hanging out around your car. You can buy a camera that has motion detection so the camera will start recording if anything moves near the sensor. My doorbell camera often records bugs flying around my light…

That’s five reasons but I’m sure there are plenty more if we really start to look for them.

I don’t have a dash camera in any of my cars but I’m sure one is coming this Christmas.

Yup, that will be another car accessory that I can plug into my 12v accessory jack.

#6 For the insurance companies so they can see who is at fault in an accident if you have one.

This is the number one reason why people are buying dash cams. I was surprised to learn that many insurance companies offer discounts on car insurance when you buy a front and rear dash cam. Check with your auto insurance company to see if they provide discounts for installing a dashcam.

Dash Cam Radar Detector Combo

Before you run out and buy a dash cam, you might want to check if your radar detector already has a camera.

Or better yet, you may want to buy a GPS, radar detector and dash camera combo. That way you can have 2 car accessories running off the same power. And maybe save a few bucks in the process.

Burning Cars… 

If you’re still not sure if you should buy a dash cam then imagine this.

You and your family decide to leave the Phoenix heat for the weekend and drive up to Flagstaff.

You pack up the car, kids, and spouse and off you go.

But before leaving the driveway, you click on your dash cam and start recording to trip.

At 9 AM the temperature is already above 90 degrees and the car A/C is on max cold.

The kids are playing video games or watching movies on the video display you mounted on the back of the front seats. Yup, more car accessories plugged into you 12v car jacks.

The music is playing low and you are thinking about the first thing you will do when you arrive in Flag.

As you are leaving Phoenix up around the 101, you can see smoke bellowing out of a car up ahead.

The kids and wife ask, “where’s all the smoke coming from?”

As you drive closer you can see multiple cars on fire and people are starting to slow down.

The line of cars is growing and you don’t want to be stuck so you decide to keep moving.

As soon as you are safely past the burning cars – BOOM, one of the cars explodes!

Then BOOM, the other car explodes!

You just made it in time…

As you arrive in Flagstaff you decide to pull the recording and watch it.

There on the screen, you can see the footage from the rear camera as the 2 cars explode.

Wow, you caught it all on video…

The end.

This seems like an extreme but amazing dash cam videos have been caught by people who were just commuting to work.

If anything, wouldn’t it be handy having your camera record footage of the license plate of the hit-and-run car that bumps your parked car at the mall?

Look:

A dash cam is just another way people are accessorizing their cars.

We used to be happy with a good car stereo, now we need:

  • Car stereo with HD digital display
  • Premium speaker system and amplifiers
  • Video displays for the front and rear seats
  • Radar detectors with GPS tracking
  • Dash camera for the front, rear, and internal recording
  • On-board computer systems that have conversations
  • Car security systems with motion detection and GP tracking
  • Built-in WiFi for the mobile office

Yup and most of these gadgets are powered by your car’s 12v system.

Almost forgot…

Let’s not forget the car computer that keeps the vehicle systems working. That’s right, engine, transmission, and even tire pressure all talk to the on-board car computer.

If you love gadgets, then for no other reason, you need a dash cam for your car because it’s a gadget!

Wrap up…

What dashcam should you buy?

We covered car accessories, specifically dash cameras.

Don’t get any crazy ideas…

It’s your call if you think you need one, or two, i.e. front and rear dash cam.

What I’ve found during my research is dash cameras are easy to install and operate and can come in handy for personal or professional use.
