Answer:
Mode Name: RS-485, half duplex, 2 wire based for serial data transmission
Reason 1: less noisy
Reason 2: around 32 receivers allowed, and that is enough for the requirement mentioned in this question.
Explanation:
Serial data transmission is of two types, which are synchronous data transmission and asynchronous data transmission. However, here continuous transmission is required, and hence no stop is required. Hence, it's the Synchronous data transmission. Also, you need to only transmit at a time from one transmitter, and no receiver or the screen is going to respond in that time, considering AI surveillance is not in progress meanwhile. However, we have 4 wire, full-duplex RS-485 also available, though here we need only 2 wire half-duplex RS-485. And this will certainly cater to our requirements. And we can but should not use RS-422A as the number of receivers, in that case, is limited to merely 10.
