I build my cameras in ammo cans so I remove the MS20 from the original housing. I'm wondering how important the white shield that came in the MS20 is. Is there a down side to just leaving it out? Or mounting it it upside down? I don't use the photocell feature so I don't need a sun shield.

It is my understanding the white shield helps direct and focus the PIR. I have read posts from  others here that order replacement fresnel lenses.  I am sure if you do a search on fresnel lense you will find them.

Hope this helps.

I found this in a search

Perhaps I should have been more clear. The shield I'm talking about is not the fresnel lens. I have that already in place. The shield is the molded white plastic piece that fits over the PIR and photo cell and covers all the other components on the board.

oh sorry .... I think the white piece is just to get the proper spacing between the frensel and the sensor.

Does anyone else find it hard to express or interpet things in written words like I do : )

I just toss them.  They may help fosuc the IRheat to the sensor, or they might be a light collector for the CDS light sensor.  Either I havn't found it necessary to use them

You can mount them upside down too it doesn't make a bit of difference and you can use the test switch for 2 delay times as well.

They spent money on it for some reason but I don't know if it's for the Light Sensor to sense day/nite better or to reflect the hot sun off the electronic components.

I use it tho
