CS SD NAND in Smart Video Doorbell Products
Since 2016, smart video doorbells have seen significant growth in both volume and profitability, with the primary market still being overseas. However, domestic sales have also started to rise steadily.
Recently, we’ve received some inquiries from customers in the video doorbell industry. They mentioned the need for a local, large-capacity storage chip. We had previously known that NOR Flash was sufficient for this type of product. So, why is there now a need for a larger storage chip?
We summarized the issues and found the following reasons:
Wi-Fi Connectivity Issues: Since smart video doorbells connect to backend systems via Wi-Fi, when the Wi-Fi connection is unstable or the signal is interfered with, they need to locally cache a short video. In this case, NOR Flash's capacity is insufficient.
Fast Startup Speed Required: Smart video doorbells need to start up extremely quickly. The time between pressing the button and capturing the first frame of video should be as short as possible. The system prioritizes enabling the camera and capturing the video signal, followed by encoding. This requires a large-capacity local chip to store the video.
Outdoor Use: Smart video doorbells are typically installed outdoors, so they need to be waterproof, stable, and resistant to theft.
Previously, customers used some T-cards, but they encountered the following issues:
Insufficient Waterproofing: The product did not meet waterproof standards, and the customer rejected it.
Prone to Contact Issues: This led to problems with the device's performance.
Easy to Steal: The T-card was vulnerable to theft.
Inconsistent Quality: The quality of T-cards varied, resulting in a high return rate.
The CS Brand SD NAND with 128MB and 512MB capacities is pin-to-pin compatible, offering customers more flexibility in their choices. Therefore, we believe that as smart video doorbell products continue to grow in popularity, the use of SD NAND in these devices will increase significantly.
