Modern tracking beacons are compact. It should also be borne in mind that the antennas they use are built-in type. Models are most often installed low-frequency, but in this case, much depends on the manufacturer. The most popular devices of this type are considered among motorists.
Thus, a stolen car can be found quite quickly. However, modifications for tracking a person are also on the market. They are produced in different shapes and vary considerably in parameters. On average, such a beacon costs around 4 thousand rubles. However, you can do it yourself.
Homemade device with a pulse trigger
With a pulse trigger, how to make a tracking beacon? In fact, assembling a model of this type is quite simple. First of all, it is important to choose a high-quality photoresistor. As a rule, it is used shortwave. For these purposes, operational-type amplifiers are additionally required. Recently, bipolar transistors have been used directly, but reflex modifications are also often found.
Next, to make such tracking beacons with your own hands, you need to install rectifiers for better signal conductivity. Different types of filters cope with interference in devices. Controllers are used to adjust the beacons. As a rule, they are available on the market in the capacitor type. It is important to install the trigger directly near the transistor. In this case, the amplifier must be located near the rectifier.
Inertial Amplifier Device
With an amplifier of this type, how to make a tracking beacon at home? In order to start the assembly work, the photoresistor is first of all standardly procured. In this case, the rectifier can be selected for the model series PP20. Only after that the transistors are soldered to the device using a blowtorch. At the end of the work, it remains only to install the controller. To use it in this case is more expedient than the capacitor type. For the normal operation of the amplifier, many experts recommend soldering strainers.
How to choose a model?
First of all, when buying a beacon, it is important to evaluate the power of the model. For an automobile device, this parameter is 20 V. Chips in many models are installed in the MT series. Some devices have a cold start function . Processing data on average takes 20 seconds. It should also be noted that the frequency of the photoresistors are quite different. Most often, you can find models with a parameter of 12 Hz. But it is worth remembering about the storage conditions of the device. As a rule, low temperatures do not like beacons. A good model in our time will cost about 5 thousand rubles.
Models of the Navix company
This company, as a rule, produces GPS tracking beacons for cars. They are quite compact in size and easy to install. The inputs for many models are composite. In this case, the connection of the beacon to a personal computer can be carried out. In addition, it should be borne in mind that the devices of the presented brand are able to work at different frequencies. In this case, much depends on the battery power. In some cases, models are available with LED backlight. At the same time, the indicators in the devices are very different. A good tracking indicator of this company will cost around 4 thousand rubles.
Reviews about "Navix S30"
Many buyers respond positively to this type of beacons due to high-quality chips. In this case, the device is capable of operating at a frequency of 12 Hz. The function of the cold stratum in the presented copy is available. This model is very simple to install, and it does not take up much space. The device is able to operate on batteries with a capacity of more than 20 V. The antenna in this case has a built-in type. In addition, it should be noted that the indicated beacon weighs only 50 g. The display system is standard. The specified model does not need to be configured. In addition, it should be noted that the rectifier in the presented product uses shortwave. This tracking beacon on the market will cost the buyer 4,500 rubles.
Opinion about the "Navix S20"
To date, this tracking beacon is quite in demand. This is primarily due to a high-quality photoresistor. Moreover, the controller in this modification has a condensate type. You can adjust the frequency of the model. Thus, it is possible to connect the beacon to batteries even at 15 V. The chip in this device uses the MT series. It should also be noted that a cold start function is available in the device. The visual indication in the device can be turned off if desired. It does not need to be configured. Directly connecting the device through a coaxial output. There is this tracking beacon in the store about 4800 rubles.
What is being said about the Navix M2?
Many buyers consider the presented beacon to be quite reliable. In this case, the photoresistor is of the short-wave type. It should also be noted that the device is compact and does not take up much space. In this case, the frequency parameter is at 13 Hz. In installation, the indicated beacon is quite simple. Car batteries are suitable for it with a capacity of not more than 20 V. The chip in the indicated beacon has a series of CTs. It should also be noted that the sensitivity of the device is quite high. The visual indication in the presented model can be disabled by the user. This lighthouse stands on the market in the region of 5 thousand rubles.
Models of the "Tracker" trademark
Beacons of this brand in terms of their parameters are quite different. The company produces models for both cars and people. Modifications with open type rectifiers are considered to be the most popular in our time. Photoresistors in devices are most often installed low-frequency. It should also be noted that the sensitivity parameter for most modifications fluctuates around 8 microns. If we consider automotive devices, the power of these models is carried out from batteries with a voltage of 20 V. A quality beacon of the brand will cost around 4,500 rubles.
Reviews on "Tracker 2099"
The indicated beacon for tracking a child is very popular in our time. However, the disadvantages of the presented device are also there. First of all, it is important to mention the lack of a cold start function. At the same time, there is no way to turn off the visual indication in this model. The tracking accuracy of the presented beacon is quite high. In this case, a high-quality photoresistor is used.
If you believe the feedback from consumers, then the device breaks extremely rarely. You can connect the device to a personal computer via the USB connector as standard. In addition, it should be noted that this model does not cost much on the market, and you can buy it only for 4200 rubles.
Description of the model "Tracker 3001"
