Devices connected to a network segment are called network devices. They are usually divided into 2 groups: User devices. This group includes computers, printers, scanners and other devices that perform functions needed directly by the network user; Network devices.
Wireless Thermal Receipt Printer
Receipt printer is a device for printing text information, barcodes and graphic images on a receipt tape. They do not use ink, so they do not require refueling. The term of their work is determined by the resource of the thermal head. This value shows how many kilometers of checks the printer will print. The standard resource is 100 km, like a printer.
Types of receipt printers
The equipment for generating receipts has differences in many parameters, one of which is the method of applying the image. Depending on the printing method used, the following types of non-fiscal receipt printers are distinguished:
- Jet
- Matrix
- Thermal printers
Externally, the devices are similar: as a rule, they have a plastic case in the shape of a cube with straight or rounded edges, on which there are print status indicators, control keys and connectors for connecting external equipment. In the photo you can see what a receipt printer is and the features of its design.
Matrix printing
To obtain an image on matrix equipment, a coloring tape adjacent to the paper is additionally used. With the help of special needles that strike the dye tape, traces of contact with the paint remain on the paper.
Receipts printed using matrix technology are resistant to high and low temperatures and retain their original appearance even in conditions of intensive operation. This technology is often used in kitchen receipt printers (at catering establishments) to print kitchen orders or advance receipts for guests, in warehouses or in other rooms where the air temperature is low.
8 channel security camera
The 8 channel PoE security camera system refers to the one that uses PoE IP cameras which get both data and power via a single Ethernet cable. And the 8 channel PoE security camera system is popular mainly for the following reasons: Easy to install.
Uses of Security camera System
Monitoring the situation ONLINE (real time).
Such systems are used when there is constant monitoring of them by the operator, for example, in order to detect dangerous situations (fire, penetration of unauthorized persons into the protected area in order to commit actions that pose a threat to personal public or property security).
Recording of information (archiving) for the purpose of its subsequent viewing, analysis, use as an evidence base or conducting investigative and operational activities.
Implementation of control over the flow of technological processes where the direct presence of people is unsafe for their life and health (enterprises with harmful production conditions - chemical, nuclear industry).
Video surveillance can be used independently or as part of integrated security systems, for example, in conjunction with security and fire alarm systems, control systems, access control.
The scope of video surveillance has recently expanded significantly. In addition to enterprises, organizations, video surveillance is beginning to be actively used by individuals, installing it in cottages, apartments, dachas.
Ways to solve the problem
The range of action can be increased due to a special receiving and transmitting kit.
But today there are several ways to solve the problem of a small signal reception distance:
First, you can replace the antenna on the receiver with a more powerful one. Thus, the reception range will be increased by 4-6 times. Such a device can be installed both outdoors and indoors.
If it is necessary to slightly increase the radius, then you can extend it on the video camera itself.
Thirdly, you can use a wired video camera instead of a wireless one. This is due to the fact that the wired camera does not have its own built-in transmitter, it should be connected using an AV cable to the transmitter itself.
As a result, a wireless video surveillance system is obtained, the range of which can reach up to 5 km. The range value directly depends on the power of the transmitter.
Wireless speaker kit for surround sound
For listening to music at home or outdoors, the best wireless Bluetooth speakers of 2022 are ideal, which will delight with good bass, high-quality sound and long battery life. The portable wireless speaker connects to a smartphone via Bluetooth and plays music from it, powered by its own battery.
The compact device will help brighten up the workout and make you take a fresh look at already familiar melodies. There are portable models on sale with different size, form factor, design and power level, which complicates the choice. To help you, we have prepared a rating of the best Bluetooth speakers for the home, which give a powerful, surround and clear sound.
Professional Wireless HDMI Transmitter and Receiver
HDMI Wi-Fi Adapter for TV is a compact device that allows you to view images or videos from a computer or mobile device in real time using Wi–Fi. The device performs a number of other useful functions. Thanks to it, the capabilities of the TV are increasing, so users will be able to save money on buying "smart" models of equipment.
Our team has been engaged in wireless HDMI for more than 10 years. During this time, we have formed a whole block of expert knowledge (confirmed by real facts and reviews on working with equipment), which we want to share in this review.
By the standard of wireless HDMI, we will mean exactly those technologies that underlie the equipment that completely “cuts out" the cable. Here are their signs:
- Kits, necessarily consisting of a transmitter and receiver;
- The transmitter is connected to an HDMI source via HDMI;
- The receiver is connected to a TV (or projector, for example) via HDMI;
- There are no wires between the transmitter and receiver;
- The original source and receiver “do not see” the kit, it is transparent to them, as if the connection is made with a regular HDMI cable.
Why exactly such signs? Very simply, there is another class of standards that transmit HD video signal wirelessly to one degree or another, but as such, they are not “cable emulators". They don't have either a transmitter or a receiver, or neither - they're kind of virtual. These are standards such as AirPlay, Miracast and others like that - a topic for a separate article.
Gaming router netgear nighthawk
The Wi-Fi 6 standard is slowly but surely conquering the market. Many houses and apartments use old routers today, so it doesn't hurt to think about upgrading. Our test lab received two Netgear network systems, both belong to the initial segment. Netgear Nighthawk Pro Gaming (XR1000) is a gaming router based on Dumas. Orbi Wi-Fi 6 AX4200 is an entry-level mesh system that is designed to provide good coverage and high network bandwidth.
We recommend that you read our WLAN FAQ, where we reviewed the issues of setting up a home network, standards, encryption and much more. Our guide will help you figure out how to set up a wireless network and deploy it correctly.
Both devices have predecessors that we tested earlier. Namely, the Netgear XR500 Nighthawk gaming router and the Orbi mesh system. We considered the latter in different versions, of the fresh ones, we can note the more productive AX6000.
