Articles and Lifehacks

Interesting, what is gps in a tablet, miniature laptop computer, which has firmly entered our lives? For modern man It has already become commonplace to use all kinds of devices with a GPS chip in everyday life. Such devices include: trackers, phones, navigators, etc. Thanks to improvements in the production technology of these devices, GPS modules are becoming much cheaper. They are used in cameras and video recorders, including camcorders.

GPS Features, built into a tablet computer

Such a system global positioning(gps) allows with sufficient high accuracy determine the location of both stationary objects and objects in motion in three-dimensional space.

The domestic market reacted positively to the emergence of devices of this class. IN Lately There is an emerging trend of combining a tablet computer and a navigation system for cars. According to the manufacturers, the vocation of such a “combine” is development tablet computers, bringing features of a navigation system and a video recorder. Let's figure out what GPS is in a tablet. Studying the characteristics of a tablet with a GPS module, we understand that it is capable of receiving signals from navigation satellites. Consequently, when cards are uploaded to the tablet, it can process the information coming from the module, i.e. serve as a navigator.

The average person can use such a device not only in a car, but also at home, in the workplace or on vacation. This device, which provides a wide range of capabilities, is an excellent assistant because it makes the user’s life much easier. Advantage car tablets- convenient location of buttons and compact screen.

What can a GPS tablet do?

Developing the tablet computer market, Japanese manufacturers tried to integrate a GPS chip into the tablet, but this led to a significant increase in the price of the device. However, such computers have become widespread among users. With such a popular device you can: read books in electronic form, watch movies, play games, listen to the radio (music), work on office programs, and also use the DVR and navigator functions. In addition, you can go online anywhere where there is GPS coverage from the operator, and also send mms or sms.

You can make a video call via GPS (although not of sufficient quality). Such devices have gained wide popularity among people leading active lives. A significant portion of budget devices do not support even 50% of the above functions.

The GPS module is a radio receiver that is designed to determine the location of receiving antenna at the current time based on the time delays of the arrival of radio signals.

Many people often confuse concepts such as GPS and GPRS. GPRS technology intended for access to mobile internet, System technology) means satellite navigation system. The GPS receiving module does not transmit anything, it only receives data from satellites and determines its location thanks to the solution mathematical problem. In order for the device to determine its location (coordinates), it is required that the device sees at least four satellites. The more satellites the GPS module sees, the more accurate the coordinates will be. The receiver sensitivity and operating speed are determined by the microcircuit used in the device. Speed refers to how quickly the device is able to determine coordinates. Sensitivity refers to the receiver's ability to detect maximum amount satellites.

GPS navigators can be divided into two types: professional, which have high accuracy in determining coordinates, and household ones. The first ones found application in the military sphere, in geodesy, cartography, but household ones can be found in almost any area modern life. Professional devices differ high quality manufacturing not only components, but also antennas, software, operating frequencies, increased energy reserves, and most importantly - price.

Why do you need a GPS module? First of all, these devices can be useful to motorists. After all, even in his hometown You don’t always know how to get to this or that place. GPS devices help not only to get to a given street, but also to accurately determine the required house number. These devices can also lay optimal route before specified address, avoiding traffic jams and roads with oncoming one-way traffic, as well as streets and emergency areas closed for repairs. A GPS navigator is also indispensable for traveling to unfamiliar places. It will help you quickly get to any city and any address you specify.

However, you should not think that these devices are needed only by motorists. It can also be indispensable for pedestrians, especially tourists. So, a GPS module for a tablet or mobile phone can help a traveler navigate a foreign city, find any attractions, shops, markets, etc., and most importantly, help him return back to the hotel. And you won’t have to, without knowing the language, pester passers-by to show you the right path.

Many lovers active rest, such as hunters, mushroom pickers, and fishermen, often use GPS navigators: they help to get out of any slum and return to civilization.

Also similar device helps find stolen equipment. For example, it can help determine the location of your device, which greatly helps in the search for stolen items.

Finally, DVRs have firmly and, undoubtedly, entered Russian automotive life for a long time. However, if for some they are just an opportunity to launch an adventure on Youtube in order to “become famous” for their road “feat”, then for millions of other drivers this is a really effective means of clarifying controversial transport situations.

It is worth dwelling on this most important use of them. For what? Any recorders can record pictures. However, to verify the authenticity of recorded video facts, great importance will have evidence of the location and time of recordings. Therefore, a combination of a navigator and a DVR works better as “witnesses”.

The GPS module is shaped like a tablet, exactly copying the base of the DVR, and connected to it with a tail cable. It is especially profitable to buy a recorder with a vertical housing. This form factor allows the device to be installed between the rearview mirror and the glass. The main thing is that the control buttons of the device do not cover, and that the camera “looks” more into the glass cleaning sector with the right wiper.

It is enough if the fastening of this equipment is provided by double-sided tape. So, if necessary, your recorder can be removed, leaving only the GPS module on the glass. Although, of course, the adhesive tape connection makes the structure stationary, because it is not designed for repeated removal. An important advantage of “advanced” recorders is the ability to synchronously connect a second camera.

It seems not necessary to have separate key switch on if you like automatic start of recording (in power-on mode). When turned on for the first time, the GPS module can pick up satellites for more than a minute, but the next time it is turned on, the signal will be processed faster.

Meanwhile, it makes sense to connect recorders not to the cigarette lighter, but to constant source nutrition. Then, after several minutes of standing and, accordingly, the absence of vibrations, the parking mode is activated.

Such DVRs themselves transform into security cameras. They are not recorded continuously, but only when the built-in shock sensors are triggered. Sometimes this option requires purchasing an optional CVR/DPC cable, with a voltage control unit that turns off the recorder if the battery starts to run low.

It is preferable to choose a DVR that normal mode can take screenshots, as well as save fragments separately, while recording the episode a few seconds before and a few seconds after pressing one button. Each file must contain data on the coordinates of the location and time of recording.

It’s good if the “stuffing program” is capable of assigning coordinates to Google Maps. With its help, you can use maps to track your route in a clear and convenient way. The video resolution should be enough to read the license plate of the car not far ahead.

So, if you want to buy a DVR to monitor the situation on the road, evaluate all the listed parameters. But which one is the most important as a witness, have no doubt - this is the navigation module.

Upon purchase vehicle Every owner strives to install video recording equipment almost immediately. Today in retail outlets There is a wide variety of models that differ in configuration, functionality and cost. A regular recorder performs the function of video recording events occurring on the road or parking lot, as well as storing the footage on a removable or built-in storage device. Before you choose optimal model video recording devices, the user should pay attention to the existence of integrated (complex) devices. Often, car enthusiasts began to install a DVR with GPS. Devices that contain this modular mechanism are distinguished by a wide and useful functionality.

A video recorder with GPS allows you not only to record ongoing events, but also to do so in a more informative and meaningful way.

Thanks to this component, the motorist will be able to obtain comprehensive information about the location of the vehicle, speed limit, trajectory and route taken. It is known that information obtained during recording by a DVR has evidentiary value. By purchasing models with GPS, you can get a number of advantages in the event of a controversial (emergency) situation.

What is a GPS module of video recording equipment?

The concept of GPS itself defines a satellite navigation system, which is perhaps the most popular in currently. Using DVRs with GPS, you can determine the location of the car by linking it to a satellite to establish exact coordinates. From the received coordinate information, the motorist can calculate the distance traveled and speed limit.

All necessary information data can be displayed on the built-in monitor, and also displayed on top of the resulting video image, along with the exact date and time of a specific event. All information received from the GPS module is saved into separate video files. IN modern models There may be a special player with which you can view not only the footage, but also the trajectory of movement in a schematic form.

When choosing integrated models, you should pay attention not only to the characteristics of the module itself, but also to the parameters of the satellite signal receiver.

In order to choose a high-quality recording device with a good GPS receiver, it is recommended to purchase models with remote module, since the built-in element can transmit information with a small error. A good example The integrated video recording device is Akenori equipment of the DriveCam 1080PRO modification. This equipment can also warn you when you are approaching speed meters.

Selecting a recorder equipped with a GPS module is very labor-intensive. First of all, the user must determine the range of primary goals and objectives, namely the need to display coordinates. Most modern DVRs that belong to the average price range, equipped with a G sensor and a modular GPS mechanism.

Is it worth purchasing 2 in 1 video recording equipment?

When choosing a conventional recording device, the user must take into account certain aspects and parameters, and when purchasing a device equipped navigation function- other. There is a sufficient quantity in retail outlets multifunctional models. The advantages of 2 in 1 recording devices include:

Significantly lower cost of the integrated kit (if purchased separately, the total price is higher);
The combined equipment has smaller dimensions and takes up space designed, for example, for one registrar;
The equipment included in the kit is considered a kind of bonus, which may later turn out to be very necessary;
Purchasing 2-in-1 devices is considered more ergonomic (provided that the two functions are successfully combined by the manufacturers).

Main aspects of choosing video recording equipment for a car

Before choosing the optimal video recording equipment, you need to study technical specifications, functional features, reviews from other users and rating lists of common models. To equip a vehicle with a high-quality and effective video recorder with a GPS module, it is recommended to pay attention to the following aspects:

Viewing angle;
Availability of WDR option;
Permissiveness;
Type of fastening element;
Recording speed;
Recording format;
Support for removable drives;
Method of connection, configuration and control;
Power supply procedure;
Availability of additional modular mechanisms;
Number of channels;
Type of manufacturer, etc.

Even when purchasing equipment with a GPS mechanism, you need to pay attention to the viewing angle. The higher the viewing angle, the larger the capture area and, accordingly, the display of ongoing events. On average, this parameter should not be less than 120°. (so-called dynamic range) allows the device to display the same frame from different angles (exposures). This is very convenient due to the fact that the car enthusiast can choose a higher quality and clearer picture. Typically, integrated instruments are located on the windshield or front panel of the vehicle. The fastening element can be made in the form of a suction cup (Velcro) or adhesive double-sided tape. IN different situations Each of these types of fastening is convenient in its own way.

Modern video recording devices have HD or Full HD resolution (at least 1080 pixels per line).

Many devices indicate maximum resolution, however, in practice this may not be true. IN in this case It is recommended to test the equipment to obtain more realistic information about the quality of the transmitted video image. The standard recording speed is currently considered to be 30 frames (based on one second). Improved recording devices have a higher recording speed.

It is advisable to purchase models that have several recording methods (cyclic and continuous). Also important characteristic the recording format is considered. Most models have a special compression codec H. 264. The use of such a codec allows you to obtain smaller video images without significant loss of quality and clarity. The GPS option expands the existing functional set: video information is displayed on top of exact date and time, coordinates of the vehicle’s location and trajectory. If necessary, the driver can set a route and move along it according to schematic prompts displayed on the display.

Review of the best integrated car gadgets in the budget price class

Using the built-in modular GPS mechanism, the driver can view his driving history and find out exact location car, for example, 10-15 minutes ago. Many modern gadgets can not only transmit coordinate data, but also display the speed limit and trajectory. These optional features are very useful when an emergency situation occurs on the road to prove that you are right. Today you can find a number of DVR models that belong to different price classes.

Many car owners strive to purchase good budget equipment due to its low cost and relatively good quality of work.

In the article we will consider the question - is a GPS satellite signal receiver a necessary thing or an unnecessary decoration?

There can be no two opinions here - a GPS/GLONASS receiver is not only desirable, but, in my opinion, even mandatory in a DVR. For those who are purchasing a car DVR for the first time, it is necessary to understand the difference between GPS receiver om, built into the car recorder and GPS navigator. Both of them work on the same principle - they record signals from space satellites and, based on these radio signals, mathematically calculate their coordinates.

Difference between GPS navigator and GPS receiver:

Having received the coordinates, the GPS navigator can connect them with special cards for navigation and point to graphic display your location on this map. Well, then everything depends only on the type of maps installed on your navigator. You can visually see what city and what street you are on, calculate your next route and much more.
The GPS receiver in a car DVR plays a completely different role. He also calculates his coordinates using satellites, but then everything happens completely differently. The received data (and the receiver receives it almost every second) is written to special file, which is synchronized with the video file (this GPS data can be integrated directly into the video file), both of these files are written to the memory card.

In addition to GPS coordinates, the receiver can calculate vehicle speed, distance traveled, altitude above sea level and even exact time(receives from satellite). Depending on the model of the car DVR, all data, or just the coordinates, are recorded in this special file.

The DVR must be equipped with a special program to display the route of your car on Google maps

What happens next? In the simplest case, the coordinates and speed of the vehicle can be displayed and recorded along with the image. When watching a video, you can see captions over the video with the coordinates and speed of the car. But the best option there will be a special software, which, when watching a video on a computer, will display the route of your car on the navigation map.

In addition to the video itself, the program displays the position of the car on Google map, also in the lower right corner you can see the speed of the car and even the direction of movement in the form of a compass.

This screenshot is even more beautiful - the video is synchronized with the card, which is switched to satellite mode

As you can see, it is very convenient. If funds allow, be sure to purchase a car DVR with a built-in GPS receiver - you won’t regret it.

Two notes for future owners of car DVRs with a GPS receiver:

If you want to buy an external GPS receiver later, you need to know that your DVR must support the connection external sensors and specifically the GPS receiver. If it is not equipped with such a function, it will not be possible to connect an external GPS receiver.
Often, sellers of car DVRs claim that the presence of a built-in GPS receiver turns ordinary video recording into full-fledged evidence (for example, in the event of an accident), which can be legally used in court proceedings. This is wrong. It is possible that such DVRs exist, but they must be certified by government agencies and sealed to prevent external influence. Such recorders could probably be used, for example, on a police car or ambulance. Your video recording, with or without GPS data, can be accepted as evidence in court proceedings only by the decision of the judge - it all depends on him!
