It may be hard to believe, but the video camera has been around for more than 100 years (Fun fact: Thomas Edison helped develop it). A while after its inception, a handheld version was created, making cameras small enough to be out of sight. This technological advancement then spurred the beginning of video surveillance.
Before there were internet-connected cameras, there was Closed Circuit Television (CCTV). For a long time, CCTV was the security camera. CCTV security cameras were installed and directly connected to monitors. Then, you could either pay someone to monitor your camera feed or review recordings after the fact. Neither of these options was ideal – the former was costly, while the latter was not helpful in preventing incidents.
Luckily, improvements in technology have made it easier and more affordable to employ surveillance systems. We can now access live feeds from our security cameras remotely, which would not be possible without the advent of wireless security cameras and IP cameras. Here are some of the more prominent milestones of security cameras.
Streaming vs. Recording Cameras
As mentioned, most wireless security cameras these days are streaming live footage rather than using CCTV. It was about 20 years ago when IP cameras entered the market and changed the security industry. At this time, the video quality and technology were not yet up to par, but over time that changed. Continuing advancements brought forth IP cameras with high quality video along with the ability to stream online and control cameras remotely.
Video Content Analytics were first introduced about 10 years ago. The integration with security cameras enables multiple functions:
One of the challenges with security cameras was poor footage with dark, unfocused recordings. Fortunately, laser focusing was introduced and provides better picture and recording in limited lighting environments. Security cameras that have laser focusing deliver improved zoom and picture quality as this feature enables nearly immediate focusing via laser. Infrared technology also improves visibility in dark conditions (much like night-vision goggles).
