How IP Surveillance Works
An IP surveillance system operates by transmitting digital video feeds over a local area network (LAN) or a wide area network (WAN). The signals are sent in the form of IP data packets, much in the same way that emails are sent between computers. Surveillance video footage is stored on either a network PC or a server where it is archived and accessible to remote users with network access.
IP cameras are connected to the network in a similar fashion as network printers and computers. They can plug directly in via an Ethernet port, thus avoiding the cumbersome coax cabling required for analog surveillance systems. Each network camera has its own IP address so that it can be located by, and communicate with, other devices on the network.
Many companies are now looking to replace their existing analog systems with IP surveillance equipment in order to take advantage of the many benefits of this rising technology. The migration process can be much smoother and cost-effective than one might imagine. Most IP surveillance systems are designed to allow for easy integration between new and old technology. By using encoders and DVRs (digital video recorders), footage from existing analog cameras can be converted and stored digitally so that they can still operate effectively as part of the new IP-based system as it transitions away from analog CCTV to a completely digital setup.
