Video surveillance devices appear to be ubiquitous these days. Individuals, companies, institutions, and businesses can use it to monitor, document, and account for what happens on their property even while they are not present video security companies.

It used to be that installing a video surveillance system and hitting record on a VCR to record what the cameras saw was standard procedure. If something goes wrong, you can go back and check the video clip to see what happened. If a criminal is apprehended, the video recording may be used to identify and prosecute them.

Today, there is a better way, which is known as Video Surveillance System Monitoring. It goes far beyond a standard surveillance system by allowing trained staff to monitor your cameras in real-time, 24 hours a day. This allows you to react quickly to a crisis and has a big impact on the outcome.

1. What is a video surveillance system?

Surveillance involves closely watching people or activities to prevent or detect crime. Video surveillance systems serve as electronic tools to monitor individuals or environments in real time or record events for later review.

A video surveillance system typically includes one or more cameras that send video and audio to a central location. The footage isn’t broadcast to the public but can be viewed live or stored for future use. Basic components include cameras, recording devices, or monitoring services. Many systems also feature one- or two-way audio, adding extra functionality for monitoring companies. You’ll need cameras, speakers (optional), and recording tools—along with other installation supplies common in A/V setups.

What is a CCTV camera?

A CCTV (Closed-Circuit Television) camera system uses coaxial cables to transmit footage from cameras to a DVR (Digital Video Recorder). This setup remains one of the most cost-effective methods for video monitoring, relying on traditional radio frequency (RF) technology.

Types of Video Surveillance Cameras

There are two main types of surveillance cameras: analog and IP/digital. Each offers different advantages depending on the use case.

Analog Cameras

Analog cameras are more affordable but offer lower resolution. Each camera requires separate coaxial and power cables connected to the DVR, limiting placement options. Because of their narrower field of view, you may need multiple cameras to cover large areas. Enlarging analog footage often results in distortion.

Despite these limitations, analog cameras are popular due to their variety and low cost. They also don’t consume network bandwidth, making them ideal for non-digital setup video security companies.

IP/Digital Cameras

IP cameras offer better resolution, clarity, and features compared to analog models. They connect through a PoE (Power over Ethernet) switch, using a single cable for power and data transfer. These cameras can be placed far from the NVR while maintaining image quality. You can digitally zoom footage without losing clarity, and many IP cameras include advanced features like motion detection and object recognition.

However, IP cameras are more expensive, require more storage, and use additional network bandwidth. Wireless-enabled models allow remote access but pose security risks, making robust encryption essential for video security companies.

How Does Video Surveillance Work?

Video surveillance footage can be monitored in several ways. Security guards traditionally watch live feeds on connected monitors. Analog systems use coaxial cables to transmit footage to DVRs, with displays often in black and white or HD color.

Modern IP cameras provide more flexibility. Their feeds are accessible through networks and can be viewed on computers, smartphones, or tablets. Many systems offer motion detection alerts, notifying authorized personnel when unusual activity occurs.

CCTV vs. Surveillance Cameras

CCTV systems transmit footage from multiple cameras to a monitor via coaxial cables. These systems are often used to secure industrial facilities or public spaces. CCTV networks focus on specific properties and sometimes integrate with intrusion detection systems for added protection.

Surveillance cameras, especially IP-based models, connect through internet protocols. These setups allow remote monitoring from different locations, enhancing security operations. CCTV cameras monitor locations continuously, while surveillance cameras offer smarter control, alerting users to potential threats.
