The domestic segment of the car alarm market is still gravitating towards budget solutions, which, however, are willingly replenished with new technologies. In this case, it is not a compromise option with a limited option that resembles the capabilities of premium packages from the best manufacturers of security systems, but a full-fledged telematic complex. In the arsenal of the Pandora 3950 DXL user is a multi-system CAN interface with remote control for remote control, auto-start and modern control capabilities of protective devices via radio relay.
System features
The communication support of the complex is based on wireless data transmission facilities and the aforementioned CAN interface. The GSM-module is responsible for the wireless type functionality, expanding the remote range of access to the system. In fact, the user can control the signaling in the reception area of his cellular operator. A special secure channel is reserved for the immobilizer, which also works with wireless tags, but in a less wide area on the 2.4 GHz frequency channel. As for the CAN bus, with its help the Pandora 3950 alarm is introduced into the on-board network infrastructure. The interaction of this interface with the functional components of the car occurs at a speed of up to 1 Mbit / s. The possibility of two-way communication allows you to organize a dialog box with a security code, according to which the owner controls almost all the security system tools.
Additional functionality
The system has several digital buses in addition to the CAN interface, which expands the possibilities of using its components on different vehicles. For example, LIN, P-Bus, K-Bus, etc. configurations can serve as alternative connection channels. To provide a higher level of security for communication channels, several data lines can be used simultaneously. This is especially true given that the kit involves the creation of up to 16 security zones, each of which in any case will have to be connected either to a wireless communication station or to the main control relay via a digital bus. Pandora 3950 developers paid special attention to protective devices. To monitor the condition of the machine, tilt, motion and shock sensors are provided. A 128-bit coded encryption system is responsible for the reliability of data transmission. Moreover, to remove the alarm from the protection mode, you will need to enter a personal emergency code.
Install Pandora 3950
The main installation work will be associated with the placement of the control unit (controller). This is the basis of any telematics system with which other functional components interact. It is desirable to install the block case in the dashboard if there is free space in its niche. Initially, a fixed base is organized at the installation site, minimizing vibrations and external mechanical influences. The Pandora 3950 controller should be fixed on it with the help of complete hardware. Then you can proceed with the installation of the radio relay. The device should be fixed as high as possible in the cabin, but so that it does not directly come in contact with metal surfaces. Mounting is carried out by suction cups or mounting tape. As an option, the alarm can be supplemented with a siren. For her, she will have to make a separate electrical circuit from the control unit to the engine compartment. The siren is placed with a mouthpiece down and connected to the drawn line.
Management process
Alarm control can be carried out using sensors, a radio relay, a complete key fob and a smartphone. The main calculation is made on the remote use of the RFID tag and the GSM channel. That is, for greater convenience, you should connect a mobile device and use the security service through a proprietary application. By means of simple previously programmed commands, you can arm the car, connect certain protection modules, activate emergency mode, etc.
A special place in the list of functions is occupied by the Pandora 3950 alarm auto-start. The key fob is programmed for the basic remote start control commands, or the system is configured for stand-alone timer operation without sending special commands. Also, if desired, the owner can combine the functions of some alarm modules with control on-board equipment. For example, temperature sensors can send information to the climate control or preheater, adjusting them to the optimal operating parameters at a particular moment.
Alarm Reviews
Although the complex can be attributed to one of the most technologically advanced alarms in the Russian market, users note many significant shortcomings. So, on the whole, the positive impressions of the wide functionality of many spoil due to the modest radius of the key fob. It works on radio communications, the maximum distance of which is 60-70 m. This is a very low access rate even for entry-level complexes. Another significant drawback is associated with the power consumption of the Pandora 3950. Reviews indicate that a fully charged battery pack sits down after a month due to high loads from the alarm. This means that the manufacturer was not able to optimize energy consumption and in terms of savings, this factor is in the red. Of the positive qualities, only multifunctionality, versatility in terms of installation, wide control capabilities and a modern level of protection remain.
Price issue
The above-mentioned shortcomings could be forgiven for the complex, if not for the high cost. The fact is that domestic alarms still lag behind foreign ones and their only advantage is financial affordability. This is partly true for the Pandora 3950 model, the price of which is 27-30 thousand rubles. But it is important to consider that similar systems with higher operating parameters from competitors can be purchased for 35-40 thousand. And many car owners are ready for such an overpayment so as not to encounter problems of the same energy consumption and the limited operation of the radio module.
Conclusion
The system can be useful for motorists who have high demands on the organization of remote control. Also, the Pandora 3950 complex has adequately implemented electrical engineering filling and protective equipment. Unlike many analogues, it combines the functions of an immobilizer and autostart. Often there are conflicts between these modules during clutch control, but in this case no such errors are observed. On the other hand, navigation modules can only be connected optionally, which becomes an additional expense for installation, so you should choose this solution after a thorough analysis of all the pros and cons.
