Which Hikvision video door entry system to choose: 2-Wire IP, 2-Wire HD or maybe IP?
Satellite converter with optical output.
In the case of a fibre-optic bus, the size of the TV installation is irrelevant. The signal can be transmitted over hundreds of metres or even tens of kilometres without the need for regeneration. In the case of large buildings, this greatly simplifies the backbone of the installation. A traditional installation, based on copper wires, allows the signal to be transmitted in the trunk line over several tens of metres. This distance can be increased through the use of amplifiers - although this t...
When to buy an external antenna for LTE/5G?
In many cases, when the base station is far from the mobile device, there are problems with adequate signal strength. In order to improve it, it is usually necessary to connect a suitable external antenna to the modem. Before selecting the antenna, it is necessary to check the parameters of the network signal received by the modem. To do this, run the network diagnostic panel found in the software of the router or modem, and then compare the parameters with the values presented below....
IEEE 802.3bt - PoE standard for higher-power network devices.
The IEEE 802.3bt standard, also known as PoE++ or 4PPoE, enables much higher power to be transmitted over an Ethernet cable. It makes it possible to power equipment with high power consumption - such as PTZ cameras with heaters, IP network speakers, laptops, monitors, lighting or information kiosks - without the need for additional power sources. This significantly simplifies installation, reduces infrastructure costs and increases network design flexibility....

One of the criteria for classification of TV systems in hotels is the programming to be distributed. The simplest systems may provide only free-to-air terrestrial TV broadcasts, whereas more advanced solutions will include satellite channels, also some premium ones (pay-TV). The content required by the owner/investor will depend on the categories of prospective hotel guests (foreign and thematic channels etc).
