Introduction

With the rapid advancement of technology and increasing concerns for safety and security, surveillance cameras have become an integral part of various industries and environments. Initially used predominantly in high-demand sectors like banks and law enforcement, surveillance cameras have now become commonplace in households, making them an essential component for ensuring security and peace of mind.

The Evolution of Surveillance Cameras

As the industry has evolved, traditional analog surveillance systems have been replaced by digital IP video surveillance systems, with IP cameras taking the forefront. The deployment of surveillance transmission lines has transitioned to IP networks as well. Consequently, almost all modern cameras, around 99.9%, are IP cameras.

Different Types of Cameras for Different Needs

Depending on the specific requirements of various scenarios, surveillance cameras come in several primary types:

1. **Dome Cameras (PTZ Integrated Dome Cameras)**

Typically used in forest fire monitoring, sea-level observation, and water management systems, heavy-duty dome cameras are designed to withstand challenging environments. They feature built-in fixed-lens cameras, telephoto lenses, infrared or laser illuminators, and advanced pan-tilt-zoom (PTZ) mechanisms. They are suitable for long-distance surveillance and are favored for their high level of specialization and functionality.

2. **Bullet Cameras**

Resembling DSLR camera bodies, bullet cameras offer flexibility in functionality by allowing interchangeable lenses. These cameras can be paired with various lenses, infrared illuminators, floodlights, and radar-based triggering systems. Bullet cameras often feature I/O expansion interfaces, making them suitable for demanding applications like road surveillance.

3. **Dome Cameras**

With the ability to rotate horizontally by 360 degrees and vertically by 90 degrees, dome cameras are suitable for comprehensive surveillance of a specific point. Large 6 or 7-inch dome cameras are ideal for vast landscapes such as factories, agriculture, and water management. Smaller 3, 4, or 5-inch dome cameras are used in compact environments like shops and homes.

4. **Turret Cameras**

Turret cameras, equipped with integrated infrared illuminators, offer a compact solution for outdoor surveillance. With excellent waterproof capabilities and cost-effectiveness, turret cameras are recommended for a variety of environments, including factories, buildings, and residences.

5. **Dome Cameras (Half Sphere)**

Half sphere dome cameras integrate features like infrared illuminators and audio capabilities. Designed for indoor use, these cameras are visually appealing and compact, making them suitable for environments like retail shops and indoor spaces.

6. **Mini Dome Cameras**

Perfect for home use, mini dome cameras feature infrared illuminators, audio capabilities, and a compact design. These cameras are widely used in households due to their small size, aesthetic appeal, and versatility.
