Surveillance Cameras: Live Monitoring And Setup Guide

Closed-circuit television (CCTV) monitors are typically used to monitor conventional security cameras. However, CCTV monitors are more expensive than computer monitors. It is possible to use a computer monitor, but you will need some extra hardware and the connections are not usually the same. Wireless webcam security systems are designed for use with computer monitors, so connectivity is streamlined.

Wired vs wireless cameras

Running surveillance cameras on a monitor can be done in a few different ways, depending on the type of camera and monitor you have. One common method is to use a digital video recorder (DVR) or networked video recorder (NVR) as a base station, connecting the cameras to the DVR/NVR and then using HDMI or VGA cables to connect the DVR/NVR to the monitor. This allows you to view the camera feeds in real-time on the monitor.

Now, when it comes to choosing between wired and wireless cameras, there are several factors to consider. Both options have their advantages and disadvantages, and the best choice for you will depend on your specific needs and preferences.

Wired security cameras are known for their reliability. They provide a constant power supply to the cameras and a stable connection, ensuring that the video and audio signals remain clear and uninterrupted. Wired cameras are also less susceptible to hacking attempts since they are not connected to the internet. However, the biggest downside of wired cameras is the installation process. Setting up wired cameras can be time-consuming and expensive, as it often requires drilling and running wires through walls, ceilings, or crawl spaces. Wired cameras are also less portable and may not be suitable for renters or those who plan to move frequently.

On the other hand, wireless security cameras offer greater flexibility and ease of installation. They don't require hardwiring, making them a more convenient option, especially for renters or those who want a quick setup. Wireless cameras are also scalable, allowing you to easily add more cameras to the system. However, wireless cameras rely on a stable internet connection, and their performance can be affected by network issues or interference. Additionally, wireless cameras may require frequent battery changes or access to power outlets, which can limit their placement options.

In summary, wired cameras are ideal if you prioritise reliability and don't mind a more complex installation process. Wireless cameras, on the other hand, offer convenience and flexibility, making them a good choice for those seeking an easy-to-install and scalable solution. Ultimately, the decision between wired and wireless cameras depends on your specific needs, budget, and how long you intend to use the system.
