In my opinion one of the greatest advances for home security systems is the development of very affordable high-resolution night-vision-enabled CCTV systems. Growing up, only banks and other places that had a lot to protect along with having a lot of money to afford security were able to get surveillance cameras. The neat thing about electronics is its continued miniaturization and easier mass production which greatly reduces cost. Another factor that goes into affordability is the continued progression of generations of electronics. The cutting-edge designs are always the highest priced. If you can afford them, go for it. However, I am on a budget and choose to buy one or two generations back. It is still fantastic stuff that will have a long service life.
For example, you can buy 4K and higher resolution cameras for surveillance. If you are a casino owner or the security manager of a government installation, then such high resolution is probably what you want. At my house a 1080P surveillance camera with infrared-emitting night-vision LEDs works perfectly.Top
