The growing numbers of intruders and thieves have made security systems upgraded. From the security guards team to the CCTV camera systems, it guarantees security measurements of the establishments. Is an analog indoor camera system best for a home security camera?

Brief history of CCTV

CCTVs have been around for decades. The invention and first use of CCTV was in 1942 in Germany. CCTV captures live video footage and is used by operators, as the early forms of CCTV in wartime to monitor the V-2 rockets.

After seven years, CCTV became a device for commercial use until today. Even residents are using CCTV systems to secure their properties while not around. These security systems will serve as their eyes while not at home.

Analogue indoor camera

Analog cameras can record images and then transfer them for analysis and storage through wired connections, such as:

  • coaxial cable
  • recording device

These cameras require a different wired power supply. Several features make analogue indoor cameras the best option for a security system:

  • Image quality. The analogue indoor camera has great picture quality with 420 TVL resolution. With quality images, it is great for analysis and probable evidence in times of security breach. Analog camera technology has a high-definition resolution, capable of up to 4 to 5 megapixel resolution. An analog camera is a perfect indoor surveillance camera with a higher frame rate.
  • Bandwidth. The Analogue indoor 420 TVL resolution is an upgraded type of analogue to the standard ones. It offers image quality and motion detection offers better quality.

    • Pan
    • Tilt
    • zoom
  • Power and connectivity. Analog cameras have separate cabling for connectivity and power.

The connectors and electrical security camera cables supply power and connectivity through twisted-pair cabling and coaxial cable. The camera provides the following:
    • audio feeds or incorporate pan
    • tilt
    • zoom

Analog cameras transmit photos wirelessly, providing a strong signal.

  • Intelligent monitoring. Security professionals can make decisions quickly to lessen the risk in case of an incident. The current video security trends will offer smart camera systems that provide valuable support and rapid response times. It triggers the alerts when detecting events that don’t comply with the pre-set specifications.
