Certainly such a biometric system of facial recognition could very well be considered as a security element. Individuals who are already approaching or already in the designated and monitored area are detected and thus anyone who is not allowed to go there is quickly and effectively detected. This could also be a factor influencing the overall amount of downward security measures.

But I think like any face recognition technology is unquestionably facing promises and challenges. It will not be long before these technologies are so advanced that they will no longer encounter problems in terms of treatment of expressions, the fight against different angles and treatment of changes in appearance of the face with beards, hats, glasses sun and others.
