How Wired Security Camera Systems Work
What is Security Camera
Security Cameras are also known as Surveillance Cameras. They are designed to monitor our movements in order to keep us safe, including our properties.
Security Cameras do not necessarily invade a person’s privacy, the main aim is to protect the public by monitoring and deterring criminal activity such as providing material evidence when a crime is committed.
The Two Types of Wired Security Camera Systems
The first step of this article is to cover the two main types of wired security camera systems.
1. The Traditional Wired Camera Systems uses analog coaxial cables and offers a relatively lower quality image.
2. The Modern Wired Camera Systems use cameras that transmit data digitally over Ethernet cabling.
Both types of cameras receive power over their respective cable types, so you don’t need to worry about their Typical Components in a Wired Security Camera Systems power at the point of installation.
Typical Components in a Wired Security Camera System
1. The actual cameras and their mountings.
2. The cables run from the individual cameras.
3. A hub device that connects all the cameras.
4. A recording system, frequently integrated into the hub device.
5. A hard drive to store recordings, and lastly
6. A monitor to view the ongoing feed from the camera system.
7. A computer to manage and control the system is required.
While most wired camera security systems have these components, the individual capabilities of each component can vary significantly. For instance, the hub device might have the ability to connect to the internet or it may just be a simple video switcher.
A Closer Look at Wired Cameras
The cameras themselves can vary. Almost all the wired security camera starter kits will give you a few identical cameras, but it’s important to match the different types of cameras to the environments they’ll be expected to operate in.
For example, if you’re going to use a camera outdoors, you should certainly look for a model that’s been designed to work in the rain, sleet, snow, and other environmental hazards.
The same goes for low light environments. In those cases, you want cameras that can see well when there’s not much light. Some cameras are sold as having “night vision”, which generally means that they are diplomatic to infrared light.
Cameras can have various fields of view and focal lengths. Make sure you keep that in mind when selecting which cameras to use for your specific surveillance spots.
Wired Security Camera Installation Overview
So what does it take to install a wired security camera system? It can be pretty difficult but the basic work includes:
1. Mounting the cameras in their correct locations. Generally by drilling holes and then screwing the mount into place.
2. Drilling holes through which to route cabling. This can be opposition because you may have to drill through a wide variety of materials.
3. Pulling and routing cable between the cameras and hub device.
4. Join the connectors for each respective type of cable.
5. Connecting the cameras to the hub device.
6. Connecting the hub device to a monitor.
7. Fixing a hard drive in the hub device or attaching the video output to a computer with a capture card.
8. While mounting the cameras and setting up the video receiver hub, video recorder, computer and monitor are all relatively easy, it’s the cabling that offers a real challenge.
