Introduction
The landscape of video surveillance technology has evolved significantly, offering a diverse range of equipment tailored to different security needs. This article provides an in-depth analysis of the various types of video surveillance equipment available, characterized by their unique features, advantages, and applications.
Analog Cameras
Analog cameras, also known as traditional cameras, transmit video signal in an analog format via cables to a digital video recorder (DVR). With resolutions typically ranging from 420 to 700 TVL (TV Lines), these cameras are suited for basic surveillance tasks where high definition is not a primary requirement.
IP Cameras
Internet Protocol (IP) cameras capture and transmit video data over an IP network, providing higher resolution options, often from 720p to 4K. They support advanced features such as remote viewing, video analytics, and easy integration with digital networks.
Network Video Recorders (NVRs)
Network Video Recorders are used with IP cameras to record and manage video footage. NVRs support multiple high-resolution channels, typically 8 to 32, and offer remote access and integration capabilities with other security systems.
Digital Video Recorders (DVRs)
Digital Video Recorders convert analog signals from analog cameras into digital format, offering storage and retrieval solutions. DVRs typically handle 4 to 16 channels and are a cost-effective option for upgrading existing analog systems.
Closed-Circuit Television (CCTV)
Closed-Circuit Television systems employ video cameras to transmit signals to a specific set of monitors. They are widely utilized in premises with higher security requirements and can be configured for various resolutions and storage needs.
Wireless Cameras
Wireless cameras offer significant installation flexibility, transmitting video data via Wi-Fi. They support various resolutions, typically from 720p to 1080p, and often include built-in features such as motion detection and cloud storage.
