Security Cameras vs Surveillance Cameras: Key Differences

In-Depth Discussion of Technical Details

In addition to core functions and application scenarios, security cameras and surveillance cameras also differ in some technical details.

Image Sensors and Resolution

Both rely on image sensors to capture light and convert it into electronic signals. However, surveillance cameras often place more emphasis on high resolution, such as Full HD (1080p), 4K, or even higher, to ensure that recorded details are clearly visible. Security cameras, while ensuring a certain level of resolution, may focus more on other features such as low-light performance and wide-angle views.

Lens Types and Field of View

Both can be equipped with different types of lenses, such as fixed lenses, varifocal lenses, and fisheye lenses. Security cameras, to achieve a wider monitoring range and reduce blind spots, may be more inclined to use wide-angle lenses. Surveillance cameras, on the other hand, may choose lenses with different focal lengths depending on the specific monitoring needs to capture details in particular areas.

Night Vision Capabilities

Night vision is crucial for 24/7 monitoring. Both types of cameras commonly use infrared (IR) LEDs to achieve night vision. However, some more advanced security cameras may employ starlight sensors or color night vision technology, which can provide clearer and richer images even in low-light conditions.

Network Connectivity and Protocols

Modern security cameras and surveillance cameras usually support network connectivity and can connect to the internet via Ethernet or Wi-Fi. They may support different network protocols, such as TCP/IP, HTTP, RTSP, etc., for remote access and management.

Storage Methods

Security cameras often support multiple storage methods, such as local SD card storage, cloud storage, and connection to a network video recorder (NVR). Surveillance systems typically rely on digital video recorders (DVRs) or network video recorders (NVRs) for centralized storage and management of large amounts of video data.

Smart Features

In recent years, artificial intelligence (AI) technology has been increasingly applied to security and surveillance cameras. These smart features include:

• Human Detection: Accurately identifies human figures in the video, reducing false alarms.
• Vehicle Detection: Identifies vehicles in the video.
