Questions and answers

Filter
  • Everything that is in U-PROX, from the idea to the engineering implementation is done exclusively in Ukraine.

  • Most of the sensors are powered by lithium batteries. They have sufficient capacity and operating temperature range.

    Thanks to the adaptive power of the radio transmitters and the optimized data transmission protocol, the service life can be up to 7 years. The shortest service life of alkaline batteries “finger” or AAA, which are installed in the keyboard – up to 2 years.

    But the replacement does not even require a screwdriver, the keyboard is removed using a regular plastic discount or bank card.

  • 15 years ago massively used wired phones, mobile phones were either business or luxury. Now almost everyone has mobile phones. It’s not only comfortable. The quality of wireless communication is steadily increasing.

    The same situation with security systems. Wired systems require high-quality cable, trained personnel with electrical education, quality installation with line inspection, construction work with drilling, wiring, and other inconveniences. All this requires a lot of time.

    As a result, we have a total cost which includes work. And compared with wireless systems, it is much higher. The wireless security system can be installed independently, the kit includes everything you need for installation.

    The U-PROX security system has U-PROX BAND radio communication technology. It has unsurpassed characteristics in range, resistance to interference, due to channel redundancy, and is very efficient in terms of energy consumption.

  • It is reliable communication that distinguishes the U-PROX security system from its competitors. We use DSTU GOST28147-89 encryption with reverse gamma, 256-bit key (3DES level).
    Any of our radio devices operates in the notification (notification) mode, not polling, that is, as soon as an event occurs, it is immediately transmitted to U-PROX. In turn, the security center confirms the reception of the data packet by sending a response. The communication is two-way, imitation-resistant: the packet contains the detector serial number and the packet sequence number, which makes it impossible to replace the detector or send the same data packet by an intruder.

    The detector periodically sends data about its status to U-PROX, notifying that it is “alive”. We call this a “heartbit”. In response, it receives confirmation and additional commands.

    If the detector is installed in a place with poor conditions, it is used:

    • increasing the radio communication power – 3 gradations of the transmitting device power are available,
    • switching the data rate to improve the sensitivity of the receiving path,
    • switching to other (backup) channels in the frequency range of 868.0 … 868.6 MHz.

    In turn, the basic U-PROX device has 2 transceivers that work simultaneously to receive signals on different channels and speeds. And of course, there is a definition of radio jamming.

  • Your device communicates with the security company via two GPRS/LTE channels and the Internet – Wi-Fi or Ethernet.

    If you try to “jam” or somehow block the communication channel, U-PROX will send a signal about it.

  • Yes, if the security system uses the U-PROX PIR Cam detector with photo fixation.

    Thanks to it, users of the U-PROX Home mobile application can receive a photo from the detector at any time by pressing one button.

    Also, when a photo is received on request, it is possible to save it to the user’s smartphone photo gallery and enlarge it if necessary.

    The owner of the security system can also configure permissions to send photos in case of alarm to security companies.

  • Wi-Fi is a wireless technology for connecting devices to the wired Internet.

    It is implemented in the all security centers (hubs).

    The central unit in this case can be placed anywhere.

    1. We believe that this is our future – in 2-3 years, wireless equipment will occupy a large part of the security systems market. Almost everything will be wireless, and prices for such solutions will decrease.
    2. Wireless solutions are fast, convenient, and reliable.
    3. Вo not spoil the interior design and renovation during installation, as require a minimum of installation work.
    4. Minimize the time spent on installing the security system.
    5. U-PROX WDC, U-PROX Wireport, U-PROX Multiplexer  and U-PROX Siren have wired inputs to which wired devices can also be connected.
  • The use of mobile applications U-PROX Home and U-PROX Installer allowed to separate system settings and management.

    The U-PROX Home application is used to control the U-PROX security system. The application implements the required set of functions:

    • Arming.
    • Disarming.
    • Arming in night mode.
    • Alarm button.
    • Event history with simple filters.
    • View temperature from sensors.
    • Add camcorders with zones.
    • Watch the video from a connected camera.
    • In the event of any failure in the system application, U-PROX brings this information to the home screen, and notify the user via Push message.

    U-PROX Installer is used to configure the security system. Through an application is performed the primary activation of the sensors

  • The security group is a logically independent unit in the security system.

    It combines a group of sensors, which is placed and removed from protection separately and independently of others.

    This can be done by a user who is authorized to manage a specific group.

  • This is a function that can work in any of the security groups.

    It is implemented as follows. Consider the example of the house. When people put guards in this mode, the sensors that protect the perimeter: doors, windows, or even the entire first floor – become active. Other sensors – indoors – inactive. So, you can move freely inside the room, and intrusion from the outside will be detected.

  • The sensors are powered by their own batteries.

    And the U-PROX security center is equipped with a lithium-ion battery, which will provide autonomous power for 24 hours.

    And if this is not enough, then you can use the design feature of U-PROX devices – an input power supply 12V DC, which means that an external uninterruptible power supply can be used, or a car battery, then the autonomous life can be increased, even up to several weeks.

  • It is very easy to install the U-PROX security system. Everything you need for installation: screws, fasteners, come complete with each sensor. The devices have simple mounts. Installation of the sensors to the required space can be done using screws or using two-way tape.

    The overall security system installation will take about 10-15 minutes.It is very easy to install the U-PROX security system.

    The overall security system installation will take about 10-15 minutes.

    1. Modern energy-saving technologies allow you to not think about replacing batteries for several years (2-7 years).
    2. 2 weeks before the full discharge, the security system will warn you and the service security organization about the discharge.
    3. Popular battery sizes are used ААА, CR2, CR123A і CR2032.
  • This is implemented using cloud technology.

    With the security panel, the system works directly, “without intermediaries”.

    With the user’s smartphone, the mediator is the cell of the device in the cloud, through which events are displayed on the smartphone and control commands from the user are passed.

  • Modern systems work via an Internet connection, this is mobile Internet in LTE networks or fixed cable.

    U-PROX uses both connections, thus providing data transmission redundancy to the monitoring station in case of blocking or jamming of GSM-communication or cable breakage.

    Control of communication with the device is provided by the monitoring panel.

  • You can prevent water leaks in your apartment or house thanks to automation devices from U-PROX. The flood prevention system warns you of an unwanted water leak in the U-PROX Home app and automatically shuts off the water supply in case of a pipe burst or a malfunction of the washing machine.

    The smart valve control and power supply device allows you to automatically shut off/open the water supply when arming/disarming the room.

    You can also create personalized schedules for arming/disarming/operating the relay/water valve.

  • We use a proprietary technology called “U-PROX BAND”, it operates in the 868.0-868.6 MHz frequency range allocated for such systems and transmitter powers allowed without licensing up to 25 MW in the basic device, up to 20 mW in detectors, 10 mW in key fobs, with dynamic adjustment (the first exchange attempt is always at minimum power).

    U-PROX BAND has significant advantages over its competitors: the length of the packets transmitted over the air is almost two times less, the optimized retry algorithm (this is energy consumption), the sensitivity of the detector receivers is higher (this is the range both in line of sight and in building conditions). The U-PROX security center has two transceivers operating at different frequencies in the permitted range, providing redundant data transmission from sensors.

    One of the “tricks” of U-PROX BAND is the function of updating the software of all elements over the air. If any shortcomings are corrected or the functionality of the device is added, then the owner and the security company do not need to worry about dismantling, sending for an update. The update will occur automatically after the automatic update of the basic device.

  • The U-PROX security system has a refined design.

    As standard, the case of devices is executed in white or black color.

    For WDC sensors, the white starter kit includes replaceable dark brown housings.

  • If the animal is no more than 25 kg, then we will install special sensors that do not react to such animals, it is not required to restrict pets in movement.

    If the animal is large, then we recommend allocating a space for it in the room, where sensors that react to movement will not be installed, there you can install a sensor that responds to glass breakage, or sensors for opening doors and windows.

  • You can install the U-PROX Security System even if you have no wired internet.

    Since the backup communication source is the LTE/GSM network (the mobile operator card is installed).

    But in this case, you lose one of the communication channels.

  • If the phone is out of network, the security system remote control and watch events will not work.

    But you can get an alarm notification if you set up a call from the device to the user’s phone. This mode is indispensable if the system operates autonomously, without remote monitoring.

    We advise you to entrust security only to specialized companies, which will monitor your facility 24/7 and respond in case of alarm notification.

    U-PROX is the best wireless device for remote protection.
