Parental surveillance
Parental surveillance based on web cameras is a simple and cheap monitoring system enabling parents to watch and hear their children from another room, the workplace, or even every corner of the world.
Parental surveillance is usually used to watch babies and small children. Typical application is monitoring the baby's sleep. Such remote watching makes things much easier for the parents who use their computers at home and can't tear away from them. Any moment they are able to see the baby on the monitor's screen.
In the case of small children the parents can monitor the playroom and be sure the children are playing safely. Another application is supervision of the job of a babysitter. The control can be performed from any location, e.g. the workplace.
The simplest parental surveillance system consists of:
  • IP camera,
  • home computer network (wired or wireless),
  • a desktop or laptop.
IP camera
A good choice is P405 K1133 or its wireless version P405W K1134. Both the models provide high quality picture and sound. For high resolution imaging one needs megapixel camera, e.g. K1135, with resolution of 1280 x 1024 pixels.
In cases where the area to be monitored is too large for one camera, one may use another device, or pan-tilt camera instead of fixed devices, e.g. P410 K1231. The camera enables the user to control pan/tilt remotely.
All the mentioned devices have been equipped with highly sensitive microphones allowing to transmit audible sound from the environment. The main feature of theses cameras is capability of remote viewing and listening (in the case of pan-tilt device - also choice of the scene) via Internet browser. The cameras have many other useful functions which are described on the catalog pages.
MPEG-4 IP Camera: Pixord P405
Wireless MPEG-4 IP Camera: Pixord P405W
Compact IP Camera: Pixord P405M (1.3 Mpix)
Wireless Pan/Tilt IP Camera: PiXORD P410W

Computer network
In a typical home computer network based on a router, the camera will be seen as another IP device. The user should only connect the camera to the router, with a network cable. In the case of wireless router (built-in access point) the job becomes even easier, due to wireless camera, e.g. P405W K1134. No cable is needed, it is enough to configure the camera and access point.
In many homes there are still used single computers directly connected to the Internet via ADSL or cable modems provided by the ISPs. In such a case the user needs to employ a router, e.g. N2990, or wireless router, e.g. N2950 (for a wireless camera).
The router has to be connected before the computer - the cable from the ISP to the WAN port of the router, the computer to one of its LAN ports (wired solution). The IP camera/s should be connected to another/other LAN port/s. In the case of a greater number of cameras there may be used additional switches, e.g. 5-port N29915, or 8-port N29918. To finish the implementation the user has to configure network devices and the cameras.
No special computer is needed. A typical, up-to-date PC or laptop will be perfect for watching video and listening to the sound from the monitored areas. For a smooth transmission, the minimum parameters are the following:
  • Processor: Intel Celeron 2 GHz,
  • RAM: 512 MB,
  • Graphic card: 64 MB RAM,
  • OS: Windows 2000/XP/2003/Vista with IE 6 or later.
The computer allows to view the video and listen to the sound from the camera via Internet Explorer, logging in to the camera. P6032 network monitoring management software is supplied with each PiXORD camera. It enables the user to view the video and listen to the sound, record the data, control pan-tilt cameras. P6032 software supports up to 32 IP cameras of PiXORD

The last thing that is needed for running the extended home network is configuration of the whole system, mainly the allocation of IP addresses of all devices. There are recommended static IP addresses. In the case of adding a router or wireless router with AP, they have to be configured as well. The same applies to AP and wireless camera. In the last stage the user can set image parameters and other functions of the camera/s, according to individual requirements.
In the case of sharing the video and audio over the Internet it is indispensable to configure the router. It consists in redirection of two ports (HTTP: 80 and RTSP: 554) to be seen from outside. This way, logging in via the Internet to the external address of the router, the user gets access to the camera. To have the access from any place in the world the address of WAN port of the router has to be a public IP address. In the case of having a private IP address the user has to contact the ISP to change it to a public one or redirect two ports in the network infrastructure (gates, routers, servers).
Another case is ADSL service. The user needs an ADSL router, e.g. N2905, N2906, N2908, or wireless ADSL router (with AP), e.g. N2901, N2903. Due to dynamic IP address it is also indispensable to configure DynDNS service. The access to camera will be possible after entering the previously configured DNS name.
The procedure outlined above applies to a single camera. When there is number of cameras, the subsequent devices have to use other ports, different from the default ones. For example, for the second camera the http port can be set as e.g. 81, RTSP as e.g. 555. For the next camera - e.g. 82 and 556 respectively, and so on. It is important that any of the ports cannot repeat itself. The final configuration of the router includes redirection of current ports and addresses of the cameras. If a camera has been configured with http port different from 80, the address in IE should be, where is the IP address, yy the port number. In the case of DNS, it will be e.g. .
