When you are buying outdoor cctv cameras, you will have to check several things before actually buying them. Most outdoor cameras that are available in the market these days are weather proof cameras. You need to understand the difference between weather proof and water proof—a distinction that most people have never been able to understand.
When cctv manufacturers say that their cctvs are weather proof, it means that they can be used in all kinds of weather. It also implies that all kinds of weather will have to affect on it. However, if you take that cctv and submerge it in water, it will stop functioning. No cctv camera is water proof hence it is important that you know the differences between the two terms.
Most modern cctvs can be used during the day and the night, in bright light and low light. This is because the modern cctvs have special technology built in called the infra red technology. When you are selecting your home cctv cameras, make sure that you look out for these features first. You will also have to select the cctv cameras depending on the desired video quality.
Each cctv camera will show the level of video quality represented by the TVL (TV line) number. The TVL is the measurement of the camera’s horizontal resolution. So, if you find that the cctv camera has a resolution of 350 TVL, that means the camera has 350 horizontal lines of resolution. You can use the aforementioned tips to get a better view of the cctv systems installation and will help you build a secure perimeter around your house.
