QTECH solutions for building video surveillance systems

QTECH is steadily developing the production of video surveillance systems, offering a variety of solutions for private and corporate customers. Our clients purchase both individual types of video equipment and ready-made sets of hardware and software for individual projects. The range of equipment meets all modern requirements for providing high-quality security and technological video surveillance at any facility from a country house to an industrial enterprise. Video surveillance from QTECH guarantees security, full control over the situation, effective management of each device - video camera, video recorder, switch via wired and wireless communication channels.

Analog video cameras

The second life of analog video cameras began with new technological solutions that brought their parameters closer to digital standards. The introduction of advanced video formats AHD, HD-TVI, HD-CVI made it possible to provide the level of Full HD 1080 quality with a resolution of 1920 × 1080 or more pixels. The combination of high light sensitivity and IR illumination makes it possible to use QTECH cameras in case of minimal illumination of the territory and even complete darkness.

Customers can choose from various modifications of analog video cameras: domed, high-speed PTZ, cylindrical. The complete set of sealed thermal housings allows you to install cameras not only indoors, but also outdoors. The lineup is represented by models with both fixed and varifocal lenses, complemented by optical ZOOM for maximum detail at long distances.

High-speed PTZ cameras Supports 360-degree fast rotation and 90-degree tilt angle changes without losing focus. Up to 220 presets can be used.

Dignity:

• video traffic is transmitted without processing delays;
• variable focus;
• extended dynamic range;
• filtering noise;
• ease of connection.

Hybrid DVRs

QTECH Hybrid DVRs are widely used in analog and digital camcorder systems. These versatile devices support multiple formats - TVI, AHD, CVI, CVBS, IP, automatically switching analog formats.

Video stream compression is performed using H.265 + / H.265 / H.264 + / H.264 codecs. Video recording is carried out with a resolution of 4K / 6MP / 5MP / 4MP / 3MP / 1080P, 720P on 8-16 channels. Video information is output to the display via VGA / HDMI video outputs.

The DVRs are equipped with hard drives up to 10 terabytes. BNC (coaxial cable) and RJ-45 (IP network) connectors are used to connect cameras. Multi-format registrars work with P2P cloud service and iOS and Android mobile platforms. The equipment is equipped with a built-in motion detector, supports video analytics functions (face detection and line crossing).

Benefits:

• affordability;
• easy to install and configure;
• extended functionality;
• remote access.

IP video cameras

QTECH offers a variety of modifications of IP cameras that can solve any customer needs for organizing video surveillance inside buildings and outdoors. You can choose models with fixed and varifocal lens, anti-vandal, all-weather, dome, cylindrical, swivel.

Outdoor video equipment in a thermal casing operates at temperatures of minus 40 - plus 60 degrees, providing protection from precipitation, dust and dirt. Darkness is not a hindrance due to the presence of IR illumination, which acts for tens of meters.

The complete set with a Sony Starvis photosensitive matrix allows you to achieve a clear image with minimal illumination, high color accuracy and color saturation. IP video cameras use progressive scan technology. Wide dynamic range allows you to capture detail in both bright and dim light areas at the same time.

3DNR function removes noise that appears in low light conditions and other reasons. BLC backlight compensation provides high-quality video images of objects against a bright background. Anti-fog function removes blur in the video image, which is caused by shooting in difficult weather conditions.

The video stream is recorded with a resolution of up to 8MP pixels at a rate of 25 frames per second. Recording length is increased and video traffic is reduced by intelligent H.265 encoding technology.

Compliance with the ONVIF standard ensures interoperability with equipment from other manufacturers. The standard allows the exchange of video, audio, metadata, control signals in real time. Thanks to the support of P2P technology, it is possible to remotely connect to an IP camera without using static IP addressing.

The power supply to the cameras is supplied through twisted-pair cable lines using PoE technology or from a 12-volt power supply unit. The PTZ dome cameras are equipped with an electric motor that allows you to quickly rotate and change the angle of inclination. The varifocal lens provides high-speed image adjustment.

IP video recorders

QTECH IP video recorders are capable of operating by recording in various modes: constantly, in accordance with the schedule, upon triggering a motion sensor. The equipment is fully compatible with all modern standards. The catalog contains PoE modelsdesigned for remote power supply of IP cameras via a cable IP network.

It is possible to customize all IP cameras connected to the DVR with a change in a wide range of their characteristics. The video archive is organized on hard drives with a capacity of up to 10 terabytes. The number of recording channels ranges from 4 to 128. The IP video recorders run Linux software, support Android, iOS (RXCamView) mobile platform applications, QTECH P2P Windows PC applications.

The bit rate reaches 320 Mbps, and the video recording speed is up to 30 frames per second. An external video monitor is connected via VGA or HDMI interface.

QSW-1500 Series Switches

For the construction of high-performance IP video surveillance systems, QTECH offers a line of unmanaged outdoor switches QSW-1500 L2 level. Part of the equipment is reliably protected from adverse weather conditions according to the IP65 class. Support for PoE functionality allows you to organize remote power supply of video cameras over an Ethernet network. Models with 4-18 PoE ports can be selected.

The series includes models with 8-20 10/100 or 10/100 / 1000Base-T ports that support auto MDI / MDIX, allowing any type of network cable to be connected. The presence of the Port Isolation mode excludes the interaction of the connected cameras with each other.

An important innovation is the use of energy-saving technology, which reduces power consumption without compromising the quality of connections. The switches automatically adjust power consumption based on the current load on the network ports.

The use of non-blocking switching technology makes it possible to redirect and filter packets at maximum speeds and ensure the maximum allowable bandwidth.

Preventing IP congestion and improving the reliability and stability of the switches are achieved through IEEE 802.3x flow control (full duplex) and transmission pause / delay in the event of a buffer overflow.

Video traffic transmission in places with no developed cable infrastructure

Wireless solutions from QTECH provide high-quality video transmission in areas that do not have a normal cable infrastructure. Customers are offered equipment of two types:

1. Modems (routers) - wireless Internet access over the networks of telecom operators 2G / 3G / 4G. Consists of an outdoor unit with directional antenna and an indoor unit that supports Wi-Fi. To work, you need a SIM-card, which is inserted into the external unit.



Benefits:

• 2G / 3G / 4G (LTE) network connection;
• ease of installation;
• control via WEB-interface;
• simultaneous connection via Wi-Fi over 10 video cameras;
• L2TP, PPPOE support.


2. Dual-band client devices - 802.11n / ac client equipment used in point-to-point or point-to-multipoint modes. The devices are designed to organize Wi-Fi bridges with average performance. The package includes two radios with a Qualcomm 2x2 MIMO chipset, supporting data transfer rates up to 300 (2.4 GHz) and 900 Mbps (5 GHz). The directional antenna provides a gain of 18 dBi, sufficient for a wireless bridge to operate at a range of 5 kilometers.
