Home LAN/WLAN system with wireless access to the Web, and IP CCTV monitoring
Modern home computer system can integrate:
  • wireless access points,
  • desktop PCs,
  • laptops,
  • NAS (Network-attached storage),
  • network printers,
  • IP CCTV cameras,
  • NVR (Network Video Recorder) - for recording video and sound streams from CCTV cameras,
  • televisions,
  • satellite receivers,
  • game consoles.
As shown below, the Internet access is provided wirelessly through the access point integrated with antenna. This allows to connect the AP with the interior network with twisted pair cable (UTP). Choice of the device depends on the frequency at which the signal is delivered from the local ISP (in the example - 5 GHz).
The central device of the internal network is access point with built-in router and Gigabit switch. It has the following features:
  • router - allows to connect many computer to the LAN, with the use of one external IP address,
  • AP - access point supporting "n" standard - allows wireless data transmission at speeds up to 300 Mb/s,
  • Gigabit switch - supports the wired part of the network, allows data transmission speeds up to 1000 Mb/s,
  • USB port allows to connect an external HDD available for all computers in the LAN,
  • built-in firewall improves security of the LAN.

Home LAN/WLAN system with IP CCTV monitoring

The network presented above consists of two main parts:
  • network linking computers and home multimedia devices,
  • IP CCTV network with IP cameras and NVR.
Each of these subnetworks uses own Gigabit switch. This solution ensures scalability of the network (successive expansion) and ensures increased reliability. Gigabit switches are the basis for implementing high-speed networks that transfer multimedia files and streaming media.
IP CCTV monitoring system consists of IP cameras and network video recorder (NVR). The IP cameras may have VGA or megapixel resolutions (1.3 - 5.0 Mpx).
Functions of the IP CCTV system:
  • NVR records the video streams from the IP cameras,
  • each computer of the home network allows to monitor live video streams the archive files from the NVR,
  • special configuration of the router allows to access CCTV data on the Internet.
Features of the multimedia PC network:
  • all connected devices can access the Internet,
  • all connected devices can access the NAS that stores and plays back multimedia files,
  • network printer/s can print files from any computer,
  • USB devices (scanner, loudspeakers, web camera etc.) can cooperate with the network via Multifunction Peripheral (MFP) & Storage Server (N3310).
The satellite receivers and televisions with Internet connectivity enable the users to:
  • watch movies on YouTube,
  • browse websites dedicated for SAT receivers,
  • listen to Internet radio,
  • upgrade the firmware.
