Closed System CCTV-Wired Home Security Cameras

Using a system of CCTV security cameras is an excellent way to maintain a secure location all hours of the day or night. With CCTV designs that can broadcast a live feed over the internet, it's now possible for owners to use their CCTV system to keep an eye on their property from anywhere in the world that has an internet connection. Setting up a CCTV system takes some planning, but a little forethought goes a long way to having a working system that can help to give you peace of mind.

What kinds of CCTV cameras are there?

There are a wide variety of CCTV cameras available, with designs using variations in shape, size, or camera type to achieve a particular goal. Some security cameras come in dome shapes, while others use the more standard rectangular shape that is widely recognized. One important factor to consider is whether the security camera uses visible light or infrared to capture images, as the two are used in drastically different scenarios. IR designs are great for keeping a location secure at night, or in low-light conditions, because they don't use visible light to create an image, they use the infrared radiation given off by a person's body to detect and build an image of their surroundings. Some CCTV systems use what are called IP cameras, which can broadcast their feeds over the internet, making it possible to see what's going on from all over the world.

What should you know before buying CCTV cameras?

Know where you want your security cameras to be positioned and what you want them to be for. There are a number of factors to consider before choosing a CCTV camera, and each question should be fully answered in order to make the most educated decision possible for your applications.

  • Position - Consider whether your CCTV cameras are going to be placed in an obvious position to deter thieves or more inconspicuously so that they can catch people unaware. The design of CCTV camera that you ultimately decide upon will be influenced by this decision.
  • Surveillance zone - Think about what you want your CCTV cameras to keep an eye on, like an entry point or long hallway. Different cameras are designed for use at different ranges. Some come with zoom capabilities so that a security team watching the cameras can zoom and pan the camera to keep watch over a much wider area than a static camera.
  • Recording versus real-time monitoring - Some cameras are designed to be used as after-the-fact evidence, and as such they record everything they see and back it up onto a data storage system of some kind. Others are intended for more real-time purposes and should be used alongside a security team that is watching the cameras for any illicit activities. Some models of camera are capable of doing both of these things, they can record everything they see to a disk or the cloud, while at the same time being monitored from a security station where they can be remotely operated to keep an eye on an ever-changing scene.
