With the continuous advancement of technology, surveillance cameras have evolved to offer a wide range of functionalities, bringing convenience to our lives. Below, we will introduce the various types of surveillance cameras and their features, including bullet cameras, dome cameras, integrated cameras, infrared day-night cameras, PTZ cameras, and network cameras.

**1. Bullet Cameras:**

Bullet cameras are cost-effective and easy to install. They lack the zoom and rotation capabilities but are suitable for fixed-angle monitoring over a specific distance. They may not provide the best concealment.

**2. Dome Cameras:**

Dome cameras offer a certain level of concealment due to their compact and sleek design. They are ideal for offices and high-end settings, as they can be discreetly suspended from ceilings.

**3. Integrated Cameras:**

Integrated cameras feature built-in lenses with autofocus capabilities, making installation and adjustment straightforward. They are commonly used in government projects, upscale buildings, malls, schools, and hotels.

**4. Infrared Day-Night Cameras:**

Infrared day-night cameras combine the camera, protective housing, infrared lights, and power dissipation units into a single device. They excel in night vision, offering advantages like extended night vision distance, strong concealment, and stable performance.

**5. PTZ (Pan-Tilt-Zoom) Cameras:**

PTZ cameras are higher in price and are suited for complex and high-density surveillance scenarios. These devices integrate cameras with pan-tilt mechanisms and can perform quick tracking, 360° horizontal rotation, eliminate blind spots, and mask privacy areas.

**6. Network Cameras:**

Network cameras process and compress captured images digitally. They transmit compressed video signals over an IP network to servers or clients. Remote viewing of real-time images can be achieved through software at the server or client end.
