Not necessarily. Wireless cameras do not always need a Wi-Fi connection to function. Some systems can record footage to a micro-SD card or a hard drive. Cameras that don’t require the internet are known as IP cameras – and are usually backed up by a cellular line or landline. We normally recommend using Wi-Fi for both business and residential video surveillance systems. Non-Wi-Fi systems are more limited in their capabilities. Moreover, they do not have options for push notifications or cloud storage. Wi-Fi-enabled systems are much more versatile and give you real-time access to the footage.
