What is the basic information about CCTV cameras?
Thinking about getting a security system for your San Jose property can bring up a lot of questions. The technology can seem complex, but the basic information you need to get started is actually quite straightforward. This guide will provide a simple, foundational overview of CCTV cameras.
First, what does CCTV stand for? It means Closed-Circuit Television. The “closed-circuit” part is key: it means the video signals are not broadcast publicly. It’s a private system where the video is sent directly from the cameras to a dedicated recorder, intended only for you to view and review for security purposes.
The Four Basic Components
Every complete security camera system is made up of four essential parts that work in harmony. While it is possible to ask, “can we install a CCTV camera on our own?”, understanding these professional-grade components is the key to a reliable system.
1. The Cameras
These are the “eyes” of your system. They capture the video and come in many shapes (like dome or bullet) and capabilities. Their main job is to see what’s happening in the areas you want to protect.
2. The Recorder (DVR or NVR)
This is the “brain.” It’s a special box that all the cameras connect to. The recorder manages the cameras, processes the video, and saves it for you to watch later. It’s the central hub of your entire system.
3. The Hard Drive
This is the “memory,” located inside the recorder. It’s a special type of hard drive built to record video 24/7 without failing. The size of the hard drive determines how many days or weeks of footage your system can store.
4. The Cables
These are the “nerves” that connect everything. In modern systems, a single Ethernet cable connects each camera to the recorder, providing both video and power in one simple, reliable wire.
Three Key Features to Know
Almost all modern CCTV systems come with these three essential features that make them so powerful and easy to use.
- Night Vision: Using built-in infrared (IR) lights that are invisible to our eyes, the cameras can produce a clear black-and-white image even in total darkness.
- Remote Viewing: This allows you to securely connect to your system from anywhere using an app on your smartphone, tablet, or computer to view live video or watch recorded clips.
- Motion Detection: This smart feature can send an instant alert to your phone when a camera detects movement, and it makes finding important events in your recordings quick and easy.
Frequently Asked Questions
Do these systems record all the time?
They can be set to record 24/7, only when motion is detected, or on a specific schedule. The professional standard is to record 24/7 for a complete record, while using motion detection to create event markers and send alerts, giving you the best of both worlds.
Can I view my cameras on my phone?
Yes, absolutely. Remote viewing on a smartphone, tablet, or computer is a standard and essential feature of any modern CCTV system, whether it’s a DVR or an NVR.
Are all security cameras the same?
Not at all. There is a vast difference in quality, reliability, and features between cheap, consumer-grade DIY kits and professional-grade systems. Professional systems use higher quality components that provide clearer video (especially at night) and are built to last.
