Types of Security Cameras By Location

Indoor Security Cameras

Designed for monitoring the inside of buildings, indoor cameras often feature sleek designs and advanced functionalities like two-way audio and high-definition video. They are used for keeping an eye on pets, kids, and overall home security.

Outdoor Security Cameras

Outdoor cameras are built to withstand harsh weather conditions. They typically feature robust housings, infrared night vision, and motion detection capabilities to monitor property perimeters effectively.

Doorbell Cameras (Video Doorbells & Intercoms)

Doorbell cameras integrate with existing doorbells, providing video and audio communication with visitors. They are excellent for enhancing home security and monitoring entry points.

Different Types of Security Cameras By Transmission Technology

Analog Cameras

Analog cameras are the traditional form of CCTV cameras that transmit video over coaxial cables. While they are more affordable, they offer lower resolution compared to their digital counterparts.

IP Cameras

Internet Protocol (IP) cameras send video data over a network, providing higher resolution and advanced features like remote viewing. They are suitable for modern security systems and can be integrated with other smart devices.

PoE Cameras

Power over Ethernet (PoE) cameras receive power and transmit data through a single Ethernet cable, simplifying installation. They offer high reliability and are often used in commercial settings due to their robust performance.

Types of Security Cameras By Form Factor

Dome Cameras

Dome cameras are named for their dome-shaped housing, which makes them discreet and vandal-resistant. They are commonly used in retail stores and public areas for wide-angle coverage.

Bullet Cameras

Bullet cameras have a long, cylindrical shape and are known for their high visibility and deterrence factor. They are typically used outdoors and provide a focused field of view.

Pan-Tilt-Zoom (PTZ) Cameras

PTZ cameras can pan, tilt, and zoom, offering extensive coverage and detailed monitoring. They are ideal for large areas like parking lots and can be controlled remotely for precise surveillance.

This state-of-the-art camera is equipped with a powerful 25x motorized zoom lens, AI autotracking, and LightHunter illumination technology, providing crystal-clear images even in challenging low-light environments.

Fisheye Cameras

A fisheye camera is equipped with a lens that captures an exceptionally wide-angle view, frequently surpassing 180 degrees. This type of camera can produce hemispherical or panoramic images. Fisheye lenses tend to distort straight lines near the frame’s edges, creating circular or bubble-like effects, mimicking the way a fish perceives its environment.

Turret Cameras

Turret cameras, also known as eyeball cameras, combine the benefits of dome and bullet cameras. They offer easy adjustment and installation, making them popular for both indoor and outdoor use.

Types of Security Cameras By Storage and Recording

DVR Security Systems

Digital Video Recorder (DVR) systems use analog cameras and convert video to digital format for storage. They are cost-effective and widely used but offer limited scalability and resolution.

NVR Security Systems

Network Video Recorder (NVR) systems work with IP cameras and provide higher resolution and easier scalability. They offer advanced features like remote access and integration with other security devices.

Cloud-Based Security Cameras

Cloud-based cameras store video footage on remote servers, allowing for easy access and management. They provide robust data security and are ideal for users who prefer not to maintain physical storage.

Types of Outdoor Security Cameras

Weatherproof Cameras

Weatherproof cameras are designed to operate in extreme weather conditions, including rain, snow, and heat. They come with IP ratings that denote their resistance to water and dust.

Night Vision Cameras

Night vision cameras use infrared technology to capture clear images in low-light conditions. They are essential for 24/7 surveillance and can deter nighttime intruders.

Thanks to 2 integrated white light LEDs, the camera provides vivid color video even in low-light conditions. For environments with pitch-black darkness, 2 infrared LEDs offer traditional black-and-white night vision capabilities.

Motion Detection Cameras

 These cameras trigger recording and alerts when motion is detected within their field of view. They help conserve storage space and ensure that critical events are recorded.

New Innovations in Security Camera Types

AI-Powered Cameras

AI-powered cameras use artificial intelligence to enhance surveillance capabilities. They can recognize faces, detect unusual activity, and reduce false alarms by distinguishing between humans and animals.

Thermal Cameras

Thermal cameras detect heat signatures, making them effective in total darkness and through obstructions like smoke or fog. They are often used in critical infrastructure protection and perimeter surveillance.

4K Ultra HD Cameras

4K cameras provide ultra-high-definition video, offering four times the resolution of standard 1080p cameras. They are ideal for areas requiring detailed video capture and forensic zooming capabilities.

Smart Home Integration Cameras

These cameras integrate seamlessly with smart home ecosystems, allowing users to control them via voice commands and automate actions based on smart home triggers.
