About CCTV Security Cameras and HD CCTV Systems:
CCTV cameras (Closed-Circuit Television) have long been a foundational technology in the world of professional video surveillance. Traditional analog CCTV systems were developed over decades, pushing the boundaries of analog signal processing. Early systems typically used standard coaxial cabling and supported resolutions up to 600TVL, 700TVL, or 800TVL — always remaining below modern HD classifications. Digital Video Recorders (DVRs) matched this standard, often maxing out at D1 or 960H resolution.
In recent years, legacy analog systems evolved into HD CCTV systems, sometimes referred to as HD over Coax. Formats like TVI, CVI, and AHD enabled high-definition video — 2MP, 4MP, 5MP, even 8MP (4K) — over the same coaxial cables used by traditional CCTV, becoming the new standards. These HD systems allow users to retain existing infrastructure while upgrading performance, making them a preferred choice for many retrofit projects.
Today’s HD CCTV setups include a wide range of components such as dome cameras, bullet cameras, PTZ cameras, and specialized models like thermal and license plate capture (LPC) cameras. Most DVRs are now hybrid recorders, often called XVRs, capable of handling analog, HD, and IP camera formats simultaneously. These systems are widely deployed across commercial, industrial, government, and mobile applications.
About DVR Cards, PC-Based DVRs, and Other Legacy Solutions:
Before purpose-built DVRs became widespread and dominant, early analog CCTV systems often relied on time-lapse VHS recorders to store video footage. As digital recording technology advanced, DVRs began to replace analog VCR setups, and with that shift, PC-based DVR systems also gained popularity. These solutions used capture cards installed directly into computers and offered significant flexibility, customization, and performance advantages at the time. While highly capable, such systems have mostly faded from mainstream use in favor of more compact and reliable alternatives. Similarly, HD-SDI cameras were an early attempt to merge broadcast-quality video with coax-based CCTV infrastructure. Though they delivered HD resolution, limitations in cabling distance, cost, and standardization prevented broad adoption. Today, nearly all professional HD CCTV systems utilize dedicated Linux-based DVRs or hybrid XVRs, designed for scalability, integration, and dependable long-term operation.
About IP Security Cameras, NVRs, and VMS Software:
IP camera systems represent the modern evolution of video surveillance. These devices connect via standard Ethernet networks and often use Power over Ethernet (PoE) for simple, one-cable installation. IP cameras offer exceptional image quality in a wide range of resolutions, with many models supporting built-in analytics, edge recording, and advanced features like AI detection, facial recognition, and object tracking.
In IP systems, the traditional DVR is replaced by an NVR (Network Video Recorder). These come in two main types: pre-built Linux-based appliances, or either pre-built VMS appliances or custom PC-based units running VMS (Video Management Software). VMS platforms are ideal for enterprise projects, offering robust features, remote access, and integration with thousands of camera models across different brands.
Thanks to the flexibility of IP architecture, modern systems are used across everything from homes and small businesses to campuses, critical infrastructure, and city-wide surveillance. Popular camera types — including dome, bullet, PTZ, thermal, and license plate capture cameras — are available in both standalone and system-integrated designs.
Whether you're maintaining legacy infrastructure or deploying an advanced IP surveillance system, today’s security camera technologies offer the performance, compatibility, and scalability to meet nearly any requirement. Explore the categories above to find the best solution for your project.
