Bullet 2MP security cameras use a visible, directional housing that suits wall or exterior mounting, while dome cameras use a compact, low-profile housing that can provide a more discreet installation. Turret 2MP security cameras use a ball-style housing that makes aiming and repositioning straightforward, making them useful when installers need flexible coverage.

When choosing 2MP security cameras, consider the required 1080p image quality, camera form factor, viewing angle, low-light performance, and whether features such as motion analytics or local storage support your project. For outdoor installation, select a model with a weather-resistant housing, such as an IP66 or IP67 rating, and review mounting, power, and network options, while indoor installations may benefit from low-profile dome or turret designs.

2MP security cameras can connect through Ethernet, often using Power over Ethernet (PoE) for both network communication and power, or through Wi-Fi on supported models. Many network cameras also support ONVIF, allowing integration with compatible network video recorders, video management platforms, and control systems, while some support local microSD storage for standalone recording or backup.

When comparing 2MP security cameras, review low-light technologies such as infrared or color night vision, wide dynamic range, and image sensors designed to maintain detail in changing or limited light. For motion detection and event recording, compare analytics that distinguish people, vehicles, packages, or animals, along with local microSD storage, network video recorder support, app access, and notification options.
