Myth No.9 ~ 'I will get a data loss if an IP product fails'

Network-based systems can offer greater protection against failure than old analogue technology, as long as systems are built using reliable components from reputable manufacturers.

Analogue systems can go down too if a camera, recorder or other key component fails. The way to minimise this risk is to choose reliable equipment from a leading brand, and to consider some duplication of equipment in critical positions. IP CCTV systems are no different, and the same principles apply. IP systems are more readily viewed in multiple locations – even remotely - and, consequently, any equipment failures can be spotted more easily.

It is important to use reliable network components. Those with experience of home PC networks will know how ‘flaky’ some domestic equipment can be, particularly wireless equipment, often needing a reboot to come back into operation. In most domestic situations this can be frustrating but not critical. Security systems are, of course, a different matter, and care should be taken to choose professional, ruggedised equipment, particularly for sensitive applications. In short, the equipment should be selected for the environment – for example, use field-hardened products
for non-air-conditioned areas.

IP has some other tricks up its sleeve, including network cameras with the capability of recording a loop of back-up information to an SD card or similar removeable media. This means that if there is a temporary problem at the recorder, backup information is also recorded at the camera.
