I need to find an alternate to using full height turnstiles for 100% access control.
My client needs to verify that all persons entering a door/portal has badged in to the door's access control reader.
My idea was to have an access control reader door followed by a short vestibule and a second access control door (similar to a mantrap/interlock, but with free egress out). Each person must present their access badge to the reader. The analytics would count the number of people that entered the first door, and compare that to the number of authorized access badge reads.
Example - If 1 person badges in, and 2 people enter through the door, the 2nd set of doors would remain locked unless the 2nd person goes back and presents their valid badge to the reader (the number of badge reads have to match the number of people that enter through the door before the second door will unlock.
We have tried IR and Photoelectric beams, but these have been troublesome, particularly if someone is carrying something large or pushing a trolley or are in a wheel chair.
My client is using Lenel OnGuard and Axis IP cameras. They are currently using Lenel VMS, but are searching for a new platform.
Your suggestions and SME knowledge would be appreciated.
