The main purpose of the security video cameras is to record all possible invasions and use it for future investigation. But that is not possible if you do not have a good camera that is capable of recording every single thing you need in clear view along with audio signals.
There are several web sources like ryalex.com.au/solution/video-surveillance-cctv/ where you can buy quality video cameras. With the quality, the camera has to meet certain other qualifications before selecting it for personal use.

The first thing you need to consider is the price. Of course you cannot cross your budget and purchase the best available one within the range. However, it is not a very good idea to spend less on the security video cameras as it has direct connection with the safety matters for you, your family and your assets.
Both wired and wireless cameras are available and the later one it little better than the first one. But the price is the major concern here and the wireless system cost much more. So if you have the chance, it is better to use a wired security system.
Not all security video cameras are easy to set up and maintain. For a small indoor surveillance, you don’t need to keep an expert all the time near your hand. So what you need is to see whether the camera is easy to install and control before making the purchasing.
Before you make the final decision, always look for the review of the camera model you selected from the previous users. From the technical details, a camera may sound really nice; but it may not deliver the best in practical.
