Hello, if you want to achieve parking monitoring, the camera behind the dash cam is still very useful, if you only want to use the back when driving, it is not necessary, and it is not convenient to use.

Hello, the dash cam can have a front camera, generally there is no need to install the rear camera, there is a condition to install it.

I don't think the camera on the back of the dash cam is very useful, so it is recommended to install only the front camera.

In fact, the role of the camera behind is not big, because it will not touch the porcelain behind you, and then if an accident occurs, the rear car rear-ends your front car is generally his responsibility.

The rear camera is not required, you can choose according to your preferences, and generally speaking, you only need to buy the front camera to prevent the porcelain.

Hello,This dash cam doesn't feel the need to install a rear camera.,But if you want to park monitoring, then install it.。

Hello,The recorder just chooses a camera in front,There is no need to install a camera in the back,Bump porcelain is mainly in the front of the car。

The back camera is generally not very useful. After all, it was met later. Normally, it is the responsibility of the rear car. Just one front one is sufficient.

It is also very necessary for you to install the dash cam behind this car, and you must be fully prepared on the road to prevent porcelain from touching, whether it is the front or the back.

Do you mean a rearview camera? In fact, it is not very useful, because the screen is too small, and the camera resolution is often not high, so it is not easy to see.

Hello, of course, the one behind the dash cam, just in case, and another one is also very convenient when reversing, just look at it.

Personally, I don't think it's necessary, because even if you touch porcelain, it's generally from the front. If it is an accident, the latter rarely says that it is its own responsibility, and there is no need to prove anything.

Hello, the camera behind the dash cam is more secure when it is necessary to install two cameras at the front and rear at the same time.

The specific rear camera needs to be installed. It depends on the needs of the individual. It can be installed if desired.

Dash cam selection precautions.

2. Stability: When purchasing a dash cam, stability is also very important, and the purchased dash cam must avoid unstable images due to quality problems.

3. Shooting angle: If you buy a dash cam, you should choose a wide-angle camera, if the shooting angle is too narrow, it is easy to leave dead angles, which affects the comprehensiveness of the recording. The most common angles are 140 degrees and 160 degrees, with a large shooting angle, a wider field of view, and more comprehensive protection.

4. Night vision effect: When purchasing a dash cam, you also need to have a certain night vision function, which can better record the night driving process, which is also very important. You should buy the best big-name products, the quality is better and more secure.

The general dash cam is a single-lens front camera, which can only capture the front of the car about 100° of view; However, there are also dash cam brands that have dual lenses, and the front and back of the dual camera lenses can be captured.

When installed, there are two wiring plugs on the rearview mirror panel of the dash cam, and the rear is pressed at the position of the license plate light, and the wiring is very easy, and you can go along the rubber strip of the body.

It is also to prevent the inevitable porcelain touching behavior in today's society.

The actual meaning of taking a picture of the car is not great, if there are people sitting in the car, the shooting is completely the people in the car, not the situation outside the car. If you really want to take pictures of the back of the car, you can buy another one to mount in the back. It's better to have one on the front and one on the front than if you buy a dual lens.

Some time ago, I bought an Antonxing dash cam, the quality is not bad, and the cost performance is relatively high.

To be honest, the dual-camera machine, the inside is to take pictures of the inside of the car, and you can't shoot the rear of the car at all, there is no need for that, if you really want to shoot the back of the car, you can install another one behind the car, which is much more useful than your dual-camera camera in the car. Anton Star's dash cam works pretty well.

Zhongheng dash cam SG60 can be taken, the front and rear of the car can be shot, and there is a collision sensing function.

Zhengzhou's Andong Star's dash cam is of good quality and cost-effective.

From a sense of security, security.

Speaking, it is better to record before and after, record a wider range of **, in case of accidents such as touching porcelain or scratching, it is more convenient to obtain evidence, and for many novices, reversing is a small test, if there is a post-recording, and the dash cam.

If it's with a screen, it's of course better if it's a front and back recording, especially in the dead zone.

Being chased, rubbing, touching porcelain or something, will have a good role in providing evidence. It is installed well before and after, the tachograph is mainly used to provide evidence for the traffic police in the event of a traffic accident, and the front and rear are installed no matter what accident can be covered, of course, the responsibility can not run away when it is in its own time!

It is very necessary to install a dash cam under the influence of the domestic environment. Pre-recording is a must, but post-recording personally feels that the necessity is not particularly large, and post-recording needs to stretch a relatively long line, which is easy to cause abnormal noise and other problems. Therefore, it is recommended to record before installation, if possible, of course, it is a front and rear video, and it is best to watch it at any time, and it can be used as a rearview mirror.

Yes, in winter, the inside of the car fogs up to know the benefits.

Show the traffic police, confirm that the rear car rear-ended me before being rear-ended by the third car, that is, I was not rear-ended by the third car, therefore, my maintenance costs must be the second car full responsibility! A small few hundred dollars avoided my 1500 loss, and it was worth having! Habitually, if you often look at the rearview mirror while driving, and find that the rear car is tight, give him a few brakes, develop this habit, the probability of being rear-ended is almost zero, there is no need to buy a dash cam.

If you have bad driving habits and skills are not good enough, you should buy one.

There are better before and after, so that you can feel at ease on the road, not afraid of touching porcelain, it helps to define responsibilities and finally say your humble opinion, the recorder is best to pick a well-known brand, it is best to have a rear camera, and the recording ability at night and the recording before the collision These functions are more practical.

Of course, the difference is very big, because ordinary cameras have dead ends, and if there is a rear-end accident, there is no way to provide enough evidence to prove that they are innocent, but at this time, the front and rear cameras can help.

The gap is still relatively large, because their body shape and appearance, and their efficacy will be different, so this also leads to a relatively large price gap.

The difference is very big, the texture of the front and rear cameras is better, and it can also meet all our needs, and the functions are more powerful and safer.

There is no need to buy a dash cam with a double front and rear recording.

The single-recording dash cam can already meet the needs of daily driving.

The front and rear dual recording dash cam is mainly an extra rear camera, so you can record both front and rear. Although it records a little more than a single-cam dashcam, the role of the rear camera is not particularly large.

It is necessary to buy a dash cam with dual front and rear cameras. 1. Although in the event of a rear-end collision, the rear car will generally be held responsible, but if the other party says that it is caused by your sudden braking or reversing, then the rear record will help.

2. In the case of an emergency such as an ambulance at a traffic light, you need to rush forward to the red light to give way, then the record will help.
