Efficient Car Cameras - A Buyer's Guide

There are countries where a video recorder is the only way to prove guilt. It's hard to get justice without hard evidence. That is why more and more Polish drivers decide to install a camera in their car. This does not apply only to people who are professionally involved in transporting people. How to choose a camera for a car so that it is useful and does its job well?

Car Cameras - Are They Necessary?

Fortunately, in our country there are no great difficulties in determining who committed a traffic violation. Officers are quite effective in dealing with a guilty verdict. However, there are controversial situations, the resolution of which is not always obvious. That is why the car camera allows you to support yourself with a tough and often undeniable material. This is useful not only in case of disputes. Thanks to this, you can help others as a witness to an accident or find the culprit in parking damage.

Cameras for cars - what is the most important parameter?

The evidence in a dispute must be undeniable, so a good DVR should capture as much detail as possible. Of course, you will be hard pressed to find one that captures everything. It's rather impossible. What should be considered before choosing? First of all, resolution is critical. The image recorded in motion is dynamic, and impacts are often constant companions while driving. If you record material in low resolution, you will get a video of poor quality, from which you will not read much. A car HD camera is the absolute minimum these days.

How to know that the DVR has a good picture?

For one group of users, 720p quality will be more than enough. Others, on the other hand, expect much better resolution, and even the 1440p found in many cameras isn't the best for them. How can I tell if a particular DVR is actually recording the correct image?

There is only one way out here, and it is actually very simple - try to find recordings from specific devices on the network and determine which webcam records material that meets your expectations.

What is the memory card for the DVR?

Another factor that can affect the performance of the hardware is where the data is stored. Cameras don't usually rely on built-in memory, so they need to be equipped with external cards. Also keep in mind that the higher the picture and sound quality, the more space the video will take up. Before buying a camera, check the maximum amount of memory that it is compatible with - 64 GB is already a lot of data.

Good car camera, or what?

Permission is just the beginning. Of course, thanks to him, you can see more details, but the final quality of the material is also affected by:

● optics;

● number of frames per second;

● lens aperture value;

● image sensor;

● recording angle.

Car Camera - Frame Opinions

According to many "experts" on the subject, a camera that records at 60 frames per second is an absolute must. However, the rule applies: the more frames per second the technique is able to capture, the less light enters the shutter. What is the effect of this? A car camera recording at 60 frames per second can capture less detail than a theoretically weaker equivalent at 30 frames per second. This can be especially felt when the sun is not at its best.

Car cameras with recording and matrix

The optics in the camera directly affects the quality of the resulting film. The better it is, the more effectively it copes with the processing of light into an image. If the manufacturer did not provide detailed information about the type of matrix (another name for the sensor) in the description of the camera you are watching, it may not make sense to be interested in such equipment. Optics is a good choice:

• Sony;
• Aptina?
• Omnivision.

Car Cameras and Viewing Angle Width

In controversial situations, a car camera with a narrow image recording range will be useless to you. Unless the situation is happening right in front of you, it will be difficult to verify what exactly happened. Therefore, be sure to pay attention to this parameter when viewing products that interest you. You only need 130 degrees to see what is happening in front of you. However, if you are looking for an internal camera, this value may be too small.

Good car camera and lens aperture

The parameter is denoted by a small letter "f" and a numerical value, for example, 1.6. The smaller the number after the letter, the more light hits the sensor. What are the implications of this? Light is essential for a well-exposed film, so the more light you have, the sharper the image. Therefore, it is best to aim for an aperture value in the range of 2.0-1.6. The absolute best models are those equipped with an f/1.4 lens.

Automotive cameras and screens

If you want to make a wise choice, the key is to find compromises. A car camera equipped with a large screen can be inconvenient and take up a lot of space on the car windshield. However, don't aim for very small screens. They often do not allow efficient navigation through the settings or menus of a given device. What to do to make the screen just right? Look for a product with a screen size of 2-2,4 inches. Of course, you can also get to cameras without a screen. You will then connect to your smartphone or tablet wirelessly.

Front and rear car cameras - is it worth it?

Usually the most important thing is what happens in front of the car's hood. Often, as a rule, the person driving into the back of this car is to blame, which is why not everyone decides on the front and rear camera. The latter, however, may come in handy in other situations. Now illegal and punishable, reckless bumper riding is almost unprovable without a rearview camera. In addition, a camera that records the image behind the car will also be useful when reversing or in a parking lot, so that parking damage can be proved.

Car camera front and rear - wireless or wired?

Much depends on the model of the car in which you plan to install the camera. Why? A dual DVR connected with a cable, i.e. with a front-rear function, will be more difficult to install on very long vehicles. It is much better to use a wireless connection of the camera to the screen.

Battery or condenser car camera?

If the device does not have Valet mode, it will start and stop depending on the power of the car. However, in order to be able to save data, it is necessary to maintain the power supply for some time. You can do this with a battery or a capacitor. The best solution is a car camera equipped with a capacitor because it will last longer than a battery. The latter have a small capacity and quickly lose strength due to frequent discharge and temperature fluctuations.

Car Cameras – Prices That Matter

Now we come to the key question for some drivers - how much does a good dash cam cost? On the market, you will find products priced from 10 euros and over 150 euros. They differ not only in price, but also in features and parameters. If your main constraint is the budget, just look for the best solution in this price range. You can buy cameras that record videos of very good quality for 400-70 euros.

Car cameras - what else is important?

In addition to the above technical parameters, there are several more features that can be found in popular webcam models. First of all it is:

● shock sensor (G-sensor) - especially useful in parking lots and parking lots;

● location tracking (GPS);

● voice commands - saving the recorded material after pronouncing certain words, for example, "record video";

● wireless communication with devices;

● active mounting function (the handle with the power cable is permanently glued to the glass, and the camera can be removed at any time).

Car camera - unnecessary gadget or necessary equipment?

Is the camera in the car just a gadget? It seems to be quite a useful and necessary tool. It's hard to expect a drop in traffic and it just leads to more contentious and dangerous situations. In addition, there are more powerful cars and less experienced drivers.

All this makes the car camera useful not only for professional drivers, but also for personal vehicles. However, which device you choose is up to you.

You can look for cheap car cameras, but be prepared to be unimpressed by the image quality and accuracy. If you have already decided that a car camera is a necessary equipment in a car, you should not save. Focus on quality and see if the details are clear, because this is a key issue in case of a possible dispute on the road.
