When it comes to video surveillance cameras, one of the most crucial functions is storing the recorded footage. Thankfully, there are several ways to achieve this. One of the simplest and most common methods is storing the footage on an SD card. As SD cards become more advanced, with increasing storage capacity and speed, it also results in higher power consumption and voltage spikes, which can cause complications. Additionally, SD card recording is susceptible to environmental changes and static electricity, posing risks to the stored footage.
On the other hand, digital cameras use various storage systems, including reusable digital film with card readers to transfer data to computers, as well as fixed or removable flash memory. Some manufacturers even have their own proprietary flash memory devices, such as SmartMedia cards, CompactFlash cards, and memory sticks. Compression routines can be applied to digital files, taking advantage of repeating patterns, to reduce their size without losing information.
