In modern vehicle surveillance and security applications, in-vehicle cameras play a vital role in helping drivers and vehicle managers improve safety and surveillance efficiency. Two common in-vehicle camera technologies are AHD (Analog High Definition) and CVBS (Composite Video Baseband Signal), which differ significantly in terms of video transmission and image quality. This article will cover both technologies to help you choose the right camera for your needs.
AHD Car Camera
AHD car cameras are an analogue video transmission technology that has been widely used in vehicle surveillance systems. Here are the main features of AHD car cameras:
High resolution: AHD cameras usually support 720p, 1080p or higher resolution, providing excellent image quality and enabling surveillance systems to capture images with rich details. This is important for identifying vehicles, pedestrians or other objects.
Good performance: AHD cameras typically perform better in high-speed motion and low-light conditions, ensuring that the surveillance system can provide clear images even in poor weather conditions.
Audio transmission: AHD systems usually support audio transmission, which is useful for recording sound or for two-way communication.
The high resolution and performance of AHD car cameras make them the preferred choice for applications that require HD surveillance and more sophisticated applications.
CVBS Car Camera
CVBS in-car cameras are a traditional analogue video transmission technology and although the image quality is not as good as AHD, they still have their uses in certain situations:
Low resolution: CVBS cameras typically offer lower image quality for applications that do not require high image quality.
Affordable: CVBS cameras are usually less expensive and are suitable for surveillance solutions with a limited budget.
Legacy connections: CVBS use standard video connections, which makes them easy to integrate with older vehicles and existing surveillance systems.
Conclusion: Choose according to your needs
When choosing between AHD or CVBS in-car cameras, you should base your decision on specific needs and budget. If you need high resolution, excellent image quality, and stable performance in a variety of conditions, then an AHD car camera is an obvious choice. However, if your needs are lower, your budget is limited, or you’re considering an upgrade on an older vehicle or existing surveillance system, then a CVBS car camera may be a more appropriate choice. In any case, understanding the pros and cons of both technologies will help you make an informed decision to ensure that your vehicle surveillance system will meet your needs.
