Glossary: Image transfer via FTP

FTP stands for File Transfer Protocol. This is a network protocol and is a method which can be used by IP security cameras to transfer images from the camera to storage.

FTP is a client/server system which means that there must be one FTP server and an FTP client. An FTP server is essentially a network connected hard disk. Whenever data has to be transferred, a client, such as an IP camera, will connect to the server. Data will then be sent from the client to the server for storage. Once data is transferred the client will disconnect. An FTP client can only connect to one server at a time but an FTP Server can allow many different clients to connect simultaneously.

This method of transfer is perfect for security applications. Let’s say a burglar breaks into a property which is monitored by IP cameras which are recording to an on-site PC. Once the burglars are inside, there is nothing to prevent them from stealing your recording PC and all your security footage stored inside. Due to the fact that FTP makes use of IP networks, FTP servers can be located anywhere in the world, so long as there is an internet connection. This means that when a burglar is in your property, the images captured are stored safely outside the property. The downside to this system is that it requires an active internet connection. If the internet connection fails your images are not stored.

FTP can also be used for storing images at home. Simply download and install a free FTP server on your home PC, set up your username and password and open your firewall on port 21. Your IP camera should then be able to connect to your PC and transfer images.
