Cyber attacks on IoT devices are on the rise in recent years, with video surveillance systems connected to the Internet also being the target of cyber attack. Resistance to cyber attack is thus becoming an important factor to look at when selecting the appropriate video surveillance system. Some models of Panasonic’s i-PRO series cameras ship with digital certificates preinstalled, and they can they can encrypt communications, detect alteration, and prevent spoofing right after being set up. By equipping with data encryption functions, countermeasures against data leakage can be performed end-to-end. This white paper explains i-PRO series security functions of communications encryption and falsification detection using digital certificates as well as data ciphers.
