Close Focus distance IPC-T5442TM-AS 6mm (IPC-HDW5442TM-AS)

Hi All

Does anyone who owns a 6mm variant of the above know how accurate the specs on the spec sheet are in relation to the Close Focus Distance? From playing with IPVM calculator, the 6mm seems to give me the reach to get people coming towards my car on the driveway. Start of driveway is about 10m, but the close focus distance value of 3.8m leaves a large part of my car in a zone that i assume will be out of focus. Front of car sits about 2.5m from where camera will be mounted.

Does anyone know how severly out of focus people become when entering closer than the close focus distance?

I have a 6mm version and find there is still very good focus at 1m. You will probably have difficulty with IR at this distance.

thanks @handinpalm . Does the smart/auto IR not back off when a person gets closer to the camera?

There are various FW versions out there for smart IR. I do not use smart IR because the latest versions of smart IR do not illuminate my areas enough, or I have multiple cameras crisscrossing IR light paths in one area and I don't want to blow out those cameras with the others IR.

Excellent response. Thanks for your help

SmartIR isn't all that smart. I do use it on some but don't think that it really works all that great on any of my cams. Especially at close distance. Still blows out faces without compensating in other ways. Some cam/scenes better than others. That's one thing that I think my Hikvision cams do much better than my Dahua cams. But between image settings and adjusting IR in various ways you can get things to work well in most all cases.
