Request for existing solutions on video frame|video detection

Hello everyone,
I am new for this community. I was looking for a community which would help me to grow in this field by sharing expertise with each other.

I am working on the request from a potential client to detect some object in video frame|video in general. At first I am looking for existing popular solution on the market. I found some, but unhappy with what they offer. Do you have any recommendation on this task?
