Introduction

Electro-Optical/Infrared (EO/IR) bullet cameras are advanced devices critical for modern surveillance. These cameras excel in environments where traditional cameras might fail, offering visual and infrared imaging capabilities.

Principles of EO/IR Bullet Cameras

EO/IR bullet cameras operate using a combination of electro-optical sensors and infrared technology. These cameras detect and convert light and heat energy into electronic signals, which form images even in low-light or no-light conditions.

Key Components and Technologies

Electro-Optical Sensors

Electro-optical sensors in these cameras capture visible light and translate it into a digital format. Their sensitivity is often measured in Lux, with high sensitivity cameras detecting light levels as low as 0.01 Lux.

Infrared Imaging

Infrared imaging captures heat emitted by objects, making it possible to view objects that are obscured by darkness or camouflage. Typical wavelength ranges for near-infrared sensors are between 0.7 to 1.0 micrometers, and for thermal infrared, 3 to 14 micrometers.

Lenses and Optics

The lens system is crucial for focusing light and infrared onto the sensors. Key specs include focal length, typically ranging from 4mm to 100mm in bullet cameras, determining the field of view and zoom capabilities.

Data Processing and Analysis

Advanced algorithms and processing units in EO/IR cameras facilitate image stabilization, target tracking, and automated detection. Video data is often compressed using codecs like H.265, reducing bandwidth usage while maintaining quality.

Parameters and Performance

Performance criteria for EO/IR cameras include resolution (typically 1080p or higher), dynamic range, signal-to-noise ratio (above 50 dB preferred), and frame rates (up to 60 fps).

Savgood Company Solutions

Savgood specializes in advanced surveillance technology, offering EO/IR bullet cameras equipped with state-of-the-art sensors and analytics. Models such as the SG-ZCM2030N support features like 30x optical zoom, auto-tracking, and intelligent video analytics.

Conclusion

EO/IR bullet cameras provide unparalleled surveillance capabilities, ensuring visibility across diverse conditions. With companies like Savgood leading innovation, these devices continue to evolve, pushing the boundaries of security technology.
