The need to remote monitoring of the object has always been considerably topical. Today, the market of video surveillance cameras (or closed-circuit cameras, or CCTV cameras) can offer devices for almost all needs that allow using CCTV cameras in any systems, including the systems for repeating and visualizing the information that comes from various sensors in monitoring systems. In this article, we will examine the example of connected CCTV cameras to a device for monitoring server rooms UniPing server solution v4/SMS and their configurations necessary for sending snapshots when sensors for visual evaluation of the environment triggered in a remote room. For example, after connecting a door sensor, we will be able to see a face of an individual, who opened the door. After connecting a smoke sensor, it is possible to evaluate actual smoke in the room. A leakage sensor shows a water level on the floor. There are also many other variants that are limited only by the administrator's imagination and the necessity in the monitoring.
To implement a described solution, you will need:
- a surveillance camera (CCTV camera). The main requirement towards the camera is the presence of Alarm IN inputs. A camera SNR-CI-DB30I is going to be used in the article;
- A monitoring device UniPing server solution v4/SMS (it is also possible to use any other device for monitoring or power controlling, equipped with IO lines, for example, UniPing server solution v3, UniPing v3, NetPing IO v2, NetPing 8/PWR-220 v4/SMS, NetPing 2/PWR-220 v4/SMS, NetPing 2/PWR-220 v3/ETH);
- Any sensor, the triggering of which is the basis for getting a snapshot from a camera. In the example, a door sensor is used.
Configuring a weekly timer in NetPing 2/PWR-220 v3/ETH power distribution unit (PDU) allows automating a manual process of switching on and off and rebooting the equipment. This minimizes a labor cost of the servicing personnel, reduces a reaction time for events and excludes a human factor for the error. A NetPing 2/PWR-220 v3/ETH IP power distribution unit can be used in server rooms for controlling a power supply of the infrastructure as well as on the remote industrial objects that are difficult to access. In addition to the main purpose, there is a feature of connecting external sensors that can control different parameters of the environment. The device can support a specific temperature, control air conditioning systems, and notify of emergency situations. All these features allow avoiding emergencies in the operation and minimizing possible financial losses.
NetPing 2/PWR-220 v3/ETH IP PDU has the next benefits:
- quick configuring of schedules for controlling a power supply to two independent sockets;
- using filters that allow setting exceptions in the schedule for holidays or days when the change is necessary;
- a stable operation of a timer and a device in the 24/7 365-days-a-year mode;
- remote manual switching on and off the equipment using a web interface or an SNMP protocol;
- using the «Watchdog» feature that allows rebooting the equipment that froze without the personnel.
It is very often that the power supply of IT infrastructure objects of small and middle offices is a bottleneck. Server rooms of small and middle companies often are not organized well, do not satisfy informational, fire, and electrical safety requirements and are limited in space. Such conditions may lead to emergency situations that are followed by downtime or, if luckily, potential risks, which can cause unnecessary anxiety about the safety of employees and business as a whole. To solve these issues, there is a range of effective practical methods to improve the operability of information equipment in small server rooms. In this article, we will examine a feature of intelligent power management of a small server group using NetPing power distribution units.
Devices for remote controlling of power supply NetPing (IP power distribution unit) can control a status of network equipment connected to them and reboot the power supply of the equipment when necessary.
In this article, the example of configuring the automatic reboot of a router connected to a NetPing 2/PWR-220 v3/ETH IP power distribution (IP PDU) unit when the Internet connection fails will be examined.
On the picture above, an approximate interaction scheme is represented: a network router with the Internet access is powered from a PWR1 socket that is controlled by a NetPing IP PDU. To test a network connection status, a NetPing IP PDU sends specific requests in the ICMP format to network resources specified in the settings. As soon as the access to the requested resources fails (i.e. they stop responding to ping), a NetPing IP PDU reboots the power supply of a router.
To implement such a scheme, there is a need to have:
- NetPing 2/PWR-220 v3/ETH power distribution unit;
- a router with the Internet access channel
A vacation time is getting closer. As any other employees, system administrators also dream about having a vacation somewhere far from their workplace. For a majority of system administrators, especially in small organizations, it is not that easy to get distracted from work even for a relatively short time. Many of them are single-handedly responsible for a status of different components of the IT infrastructure. So how an IT specialist can have a vacation being confident that a company can work the same efficiently, as usual? Before, we already examined a process of creating bots for a «Telegram» messenger in our blog. In this article, we examine one of the variants of remote controlling a power supply of the IT equipment from any location of the Earth (having the Internet access) using the integration of a «Telegram» messenger and NetPing power distribution units (IP PDUs). If necessary, an IT specialist sends a command for a socket using «Telegram». After applying a command in «Telegram», a specialist will receive a notification about a successful application of a command and a socket changes its status.
A rotation unit for air conditioners is designed to ensure the switching mode of work in two air conditioners with a specified period of time and maintain a normal temperature mode in a room in different climatic conditions.
Using a control unit for air conditioners allows to use the lifetime of main and backup air conditioners equally by switching their roles from time to time. It also automatically switches a backup conditioner on when a main one failed or it is not powerful enough.
As a rule, rotation and backing up are used in the rooms where there is a need to maintain a maximum allowed temperature, for example, in server rooms with a big number of expensive equipment. To implement a backup scheme, there is a need to make sure that a power of either one of both conditioners is enough to maintain operating climatic conditions. I.e. one conditioner operates while another one is on backup.
In the firmware of NetPing power distribution units it is possible to configure only weekly schedule (with several exceptions for holidays). In addition, there is a feature of switching on/switching off sockets according to the schedule but no more than four times a day. To bypass such limitation in the firmware, there is a need to organize a random schedule for controlling sockets in the firmware using the chain Google Calendar and IFTTT service, i.e. configure switching on/switching off sockets the unlimited number of times in a day, configure a random monthly and yearly schedule, get a possibility to control sockets from several devices (PC, tablet, smartphone) through a common schedule.
NetPing east Co Ltd. company informs about the issue of firmware updates for devices for remote controlling power supply sockets (IP PDU) NetPing 2/PWR-220 v3/ETH and NetPing 2/PWR-220 v4/SMS. New firmware versions contain implementation of new functionality and an error correction.
What have been changed in the latest version?
A gas alarm AVUS-COMBI is designed to signal about exceeding specified values for pre-explosive concentrations of methane (propane) or a massive concentration of the carbon dioxide. Design features of a gas alarm allow to install it in non-explosive areas that do not contain aggressive gasses and vapors. When using a gas alarm AVUS-COMBI with devices of NetPing company, a customer gets a ready system that can be used to control the parameters of working area of residential, administrative, public, industrial premises, garages, car parks (parking lots), boiler houses and other objects of using gas. A gas alarm has one channel and can signal to switch an output relay on or to close shut-off gas valve depending on its modification. Together with the devices of the NetPing company, the gas alarm AVUS-COMBI will allow to react to the gas leakage in time by notifying via E-mail, SMS (in NetPing devices with a built-in GSM modem) and SNMP Trap.
Technical requirements for server rooms are determined by the building code 11-2-80 for buildings of "B" category, and the "Instruction on designing buildings and rooms for electronic computing machines SN 512-78".
In the section of micro-climate and noise requirements, the next is indicated:
The sensor SWF5.1 is designed to control the presence of water and other water solutions that are non-aggressive to the elements of a sensor cable in a controlled zone. Design specifications of a sensor cable allow to install a sensor on different types of managed objects, such as tubes, flat surfaces (including metal ones). Because of a lack of contract potentials on sensitive elements, a sensor cable can be immersed in the fluid for a long time without damaging sensitive elements. When using a water leakage sensor SWF 5.1 with the devices from NetPing company, a customer receives a ready system, which can be used in all activities, where the presence of water and non-aggressive water solutions is crucial for proper functioning of the equipment and living, such as housing, air conditioning and ventilation systems, basements, Data Processing Centers (DPC), boilers, water supply and heating systems for houses and cottages (bathrooms, kitchens, heating batteries), glass facades of buildings, stock storages, etc. Thanks to having a sensor cable of a big length, a sensor can simultaneously control a fluid leakage on the vast area. A water leakage sensor SWF 5.1 together with devices of NetPing company allows to react to leakages adequately by informing via E-mail, SMS (in devices with a built-in GSM modem) and SNMP Trap.
SNMP (Simple Network Management Protocol) – is a standard Internet protocol for controlling devices in IP networks on the basis of TCP/UDP. architectures. Devices of remote control and monitoring NetPing sensors support the operation via SNMP protocol as well. One of convenient ways of monitoring is monitoring using a mobile phone.
In this article, an example of using "Monitor Master Free" software (free version) for remote controlling a NetPing device, namely controlling external devices (for example, a signal alarm or a light beacon) that are connected to IO lines in the "output" mode is described using UniPing server solution v4/SMS device, as well as controlling sockets of a NetPing 8/PWR-220 v4/SMS device as an example.

NetPing devices have built-in IO lines (input-output lines). They can be used both in the «input» mode, and the «output» mode or a «logic output» for controlling external devices. Examples of using IO lines in the mode «output»/«logic output» are as follows:
- remote rebooting of servers, which is an imitation of pushing a «Reset» button;
- remote controlling of an alarm, lighting, a ventilator;
- controlling electric lock, and electric gate at a remote site;
- controlling the elements of a «smart home»: watering plants, opening / closing blinds, water pump, boiler, electric heaters, etc.;
- remote controlling of an energy device (diesel generator, gasoline generator)
One of the most important issues of a physical security of a server equipment as well as a security of the entire IT-infrastructure is tracking and controlling access to server rooms. A tracking system must notify system administrators and technical specialists about any access to a server room or protected object 24 hours a day 7 days a week with a possibility to browse a history of events in any moment of time. Such way of informing allows system administrators to control an access to the object without using expensive access control systems, which contain different types of electronic locks, components of employee identification via electronic maps, coded key locks and other security elements.
In this article, an example of organising the system of tracking access to server room on the basis of NetPing device and a monitoring system PRTG Network Monitor will be examined. The essence of the system is in monitoring a door opening/closing sensor, which is connected to a NetPing device by means of the PRTG monitoring system, as well as building a graph of opening a door within different time intervals.
NetPing global Ltd., a developer and manufacturer of original equipment for monitoring and remote controlling of a power supply via Ethernet/Internet network, announces issuing of a new item – temperature sensor (T811) for measuring temperature values in °C. A temperature sensor (T811) is built on the basis of a digital single-chip thermometer TCN75A, with a possibility to change an address of a temperature sensor manually. It is manufactured as a board, installed into a plastic case, with a four-wire loop, which transmits the information about temperature in a digital form.
To control and monitor a corporate IT environment, it is possible to use the product from the Microsoft company named System Center Operations Manager (SCOM), which is included in the integrated management platform System Center. This product allows combining the information about the operability from different components of IT infrastructure, providing its generalized representation in one console. SCOM allows tracking services, devices and operations for many PCs in the network. Operators can rapidly estimate a state of IT environment and its IT services, run different systems and workloads using multiple representations, which show the information about a status, operability, and performance.
