Video surveillance is a broad domain that encompasses various technologies and systems designed to monitor and record activities in a specified area. CCTV and VSS are terms often used interchangeably, but there are subtle differences between them.
1. CCTV Systems (Closed-Circuit Television Systems):
CCTV stands for Closed-Circuit Television. This term refers to a private video system where the broadcast is not publicly distributed but instead, is shown on private monitors for surveillance and security purposes. Traditional CCTV systems were analog and required direct cable connections from the camera to the monitor or recording device.
2. Video Surveillance Systems (VSS):
VSS is a broader term that encompasses various surveillance technologies, including modern digital systems and traditional CCTV. It refers to any setup where cameras capture and transmit video for monitoring or recording purposes.
Modern VSS, especially IP-based systems, transmit video over the internet, allowing for remote access and monitoring. Footage can be stored on-site (on NVRs or Network Video Recorders) or off-site in cloud-based storage solutions. Highly scalable as new cameras can be added to the network with relative ease. Comes with advanced features like motion detection, facial recognition, and analytics.

Frequently Asked Questions on Video Surveillance
Choosing the Right CCTV:
There are many new CCTV features now. People might get confused about which one to buy for safety. Some companies only pick the cheapest options which may not be the best for security. Before buying or upgrading, it's important to know what you really need.
What is CCTV?
CCTV is just a tool. It needs security guards to use it properly. CCTV can be used to scare off bad people, watch areas in real-time, or look at something that happened in the past. A basic CCTV system has:
Purpose of video surveillance/CCTV
Deterrence: If people know about the CCTV and think they'll get caught, they might not do bad things. But someone who doesn't care, like a person who wants to harm themselves and others, might not be scared off by the camera.
Live Monitoring: CCTV can be watched in real time. But, staff needs to be alert and trained. Some systems can spot changes and help staff, but nothing is perfect.
After Something Happens: CCTV is very useful to look back at what happened. Moving cameras sometimes don't capture useful info, but cameras that don't move and are placed in the right spots do. It's important for the picture to be clear and not too grainy.
CCTV Quality: There are guidelines to help use CCTV properly. But not everyone knows these rules. When setting up a CCTV system, think about what it will mostly be used for, like spotting a car or a person, and set it up the right way.
What are the most common issues with video surveillance systems?
When was the term CCTV coined and what does it mean?
