Fundamental Parameters of Surveillance Cameras

Video Signal Standards: Surveillance cameras operate on various video signal standards, including PAL, NTSC, and SECAM. These standards play a crucial role in ensuring compatibility and optimal performance.

Our OHWOAI Surveillance brand offers a wide range of high-quality surveillance cameras, including IP cameras and PoE cameras.

Our PoE NVR (Power over Ethernet Network Video Recorder) systems provide efficient and convenient solutions for home security.

For those seeking a reliable and secure camera system for their homes, our hardwired PoE cameras offer enhanced protection and peace of mind.

Our outdoor cameras are specifically designed to withstand various weather conditions while delivering exceptional security performance.

With our advanced PoE (Power over Ethernet) technology, our security IP cameras ensure seamless connectivity and power supply.

The OHWOAI Surveillance Home Camera System combines the latest technology and robust security features to protect your home and loved ones effectively.

Scanning Methods: Surveillance cameras employ different scanning methods, including interlaced scanning and progressive scanning.

Interlaced scanning, represented by the "I" in specifications like 1080i, involves scanning odd and even lines in alternating fields.

Progressive scanning, represented by the "P" in specifications like 720p and 1080p, scans each line sequentially, resulting in smoother and flicker-free images.

Our surveillance camera systems utilize progressive scanning to ensure superior image quality and optimal viewing experience.

Minimum Illumination: The minimum illumination refers to the lowest level of light required for a surveillance camera to capture clear images. It is often referred to as "sensitivity" and is measured in lux (LUX).

Our range of surveillance cameras includes models suitable for various lighting conditions:

Standard cameras: Ideal for environments with an illumination range of 1-3 lux.

Starlight cameras: Designed to capture exceptional details even in extremely low-light conditions, with sensitivity below 0.01 lux.

Infrared cameras: Equipped with infrared illumination for zero lux visibility, ensuring reliable surveillance in complete darkness.

Super Starlight cameras: Offering exceptional sensitivity below 0.0001 lux, enabling clear and detailed images even in the most challenging low-light situations.

Signal-to-Noise Ratio (SNR): The signal-to-noise ratio measures the ratio between the desired signal voltage and the background noise voltage, expressed in decibels (dB). A higher SNR indicates better image quality with reduced noise interference.

Our surveillance cameras are engineered with high SNR performance, ensuring superior image clarity and minimal noise artifacts in low-light conditions.

Automatic Gain Control (AGC): Automatic Gain Control (AGC) is a feature in surveillance cameras that adjusts the amplifier's gain to maintain a consistent and standardized video signal under varying lighting conditions.

Our surveillance cameras incorporate advanced AGC technology, allowing for dynamic adjustments to optimize image brightness and clarity in different lighting environments.

At OHWOAI Surveillance, we offer a comprehensive range of security camera solutions for residential and commercial applications. Our PoE camera systems, NVRs, and IP cameras are designed to provide reliable and high-quality surveillance for your home or business. Explore our selection of home security camera systems and experience the peace of mind that comes with advanced security technology.
