There is a huge amount of equipment and a variety of solutions in the field of organization of video surveillance and alarm systems on the market today, which are very different in the price and quality. Recently, a very popular is the use of IP video cameras and digital recorders - as basic equipment, and twisted pair - as a medium of information dissemination signal and provide power to the camera. Many people call the world of analog broadcasting obsolete, as it does not provide the necessary flexibility and is more complex in terms of installation. But is it really so? After all, analog equipment has a huge plus - it cheaper than digital. From our own experience in building a video surveillance/alarm systems and valuation of various equipment/cables, HelPi Group has developed its own approach to the construction of such systems, which is the combined use of analog and digital technology. This approach provides the best value for money. The essence of our approach to build a system of video surveillance and alarm systems is as follows:
  • Using analog cameras with infrared illumination and a wide viewing angle - 88. This type of camera has a cost, which is 2-3 times lower than for the IP camera. The loss of quality in most cases is not feasible.
  • Using coaxial cable to transmit the information signal and the cable type SHVVP for camera power. Laying coaxial and power cable are while the price of one. When cameras are in close proximity to each another there is the possibility of simultaneous power of two cameras on a single physical pair.
  • All coaxial connections are made using special connectors and specialized crimping tool (see img.), which ensures the reliability and durability of contacts.
  • Use DVRs Dahau, which perform the conversion of information signals analog cameras into digital form and perform not only the necessary functions for the work with a video stream, but also possess additional functions to ensure the alarm:
    - Monitoring/recording in real time.
    - Play, record, playback recordings, backup and remote access simultaneously.
    - Displays the status of video channels: recording, motion detection, video loss and no picture.
    - The settings for each channel: privacy mask, hide for viewing, brightness, contrast, the color and the name of the camera.
    - Supports management robotic cameras.
    - Support for action when an alarm: start recording, siren, PTZ movement, e-mail and upload to FTP server.
    - Powerful Networking: Built-in WEB server, a remote access software (software) for video surveillance from mobile devices.
  • Configure and install free software for video surveillance systems on user's devices, that allows to view video via the Internet in real-time using smartphones, tablets, laptops.
  • Examples:

  • Surveillance for construction site - the company "Rovnopromekobud".
  • Surveillance for sawmill Ivano-Frankivsk region.
