Components of The Security Camera System

Prior to purchasing a security camera, it is important to understand its components: there are four integral parts to every security system: the camera, the recording system, the monitor, and the software.

Camera

The camera is the main part of any security system. There are two types of cameras: internet protocol (IP) and analog. Most systems today use the IP camera.

Video Recording System

There are two types of recording systems, an NVR-network video recorder and a DVR-digital video recorder. DVRs are more popular these days, but NVRs tend to be more compatible with IP cameras, so they are the better choice.

Monitor

A camera’s features are worthless without a monitor to view the security footage. For cameras that have 1080p or 4k resolution will require an HD monitor to fully take advantage of this feature and see all the details recorded.

Software

VMS-video management software is the brain of your security system. It will allow you to manage your recordings. It is important to choose software that is compatible with your NVR or DVR technology and that it is user-friendly.

Wired vs. Wireless Security Cameras

Wired security cameras transmit signals using wires connected to a local hub. These wired cameras are connected to electrical power sources via cable. The footage can then be viewed locally in real-time or after the fact. The footage can also be sent out to a specific network to be viewed from there. This makes these cameras more reliable, their picture clearer, and nearly impossible to hack.

Wireless

Analog security systems are more affordable and reliable. However, with the Wi-Fi system, you can view your footage in real-time, your picture is clearer, and you can store the footage for later viewing on a cloud.
