The FH8536A, FH8538A, and FH8556A are highly integrated coaxial HD camera ISP chips that support up to 4K high-definition image processing, meeting the requirements for high-resolution imaging. They feature a built-in Audio Codec supporting two-way audio transmission, and integrate various audio algorithms such as AGC (Automatic Gain Control), AEC (Acoustic Echo Cancellation), and ANR (Ambient Noise Reduction) to enhance the clarity of voice interactions. With significantly optimized power consumption, these chips reduce power usage by over 50% compared to equivalent products on the market, striking an excellent balance between performance and energy efficiency.
