What is a CCTV surveillance system?
CCTV (Closed-Circuit Television) surveillance system uses cameras to transmit signals to a specific set of monitors.
CCTV surveillance system is a closed one. Here, the footage collected is accessible only to authorized personnel. Whereas in public broadcasting systems, the footage is generally available to all.
It’s widely used for monitoring activities in areas that require high security and surveillance.
Different Types of CCTV Cameras
CCTV systems come in various types, each suited for specific needs. Lets dive in.
1. Dome Cameras:
- Used for wide angle views.
- Ideal for indoor use. Commonly found in retail stores and offices.
- Come in dome-shaped housing (hence the name); making it difficult to tell where exactly they point.
2. Bullet Cameras:
- The name comes from it’s recognizable cylindrical shape.
- Useful to get more focused, and distant views.
- Often used in outdoor spaces for long-distance surveillance.
- Weatherproof.
3. IP (Internet Protocol) Cameras:
- IP cameras come with IP(Internet Protocol) Addresses.
- Transmit data over the internet, allowing remote access.
- Offer high-quality images; advanced features like motion detection.
- Have IP address; allows control directly via IP without depending on DVR.
4. PTZ (Pan-Tilt-Zoom) Cameras:
- PTZ cameras are used in scenarios where fixed-view based cameras fail. That’s when surveillance area is large, and small areas within it need focus.
- In PTZ cameras the viewer gets wider angle views. Viewers can pan or tilt the view, also zoom in for detailed inspection.
- All these functionalities can be adjusted remotely.
- Ideal for dynamic surveillance, because viewers can zoom in to any portion of the footage and focus there. For example, if you want to focus on a particular object, person or pet in a bigger area, PTZ cameras come handy.
- Lately, PTZ cameras come in toned-down versions in consumer series, wherein they come in small sizes but offer the same features. One such example is Ring Pan-Tilt indoor camera.
5. Infrared (IR) Cameras:
- Equipped with night vision
- Capture footage in low-light or complete darkness; perfect for night-time security.
