The combo Optex cameras/PIRs "pieces" have never failed in over 10 years of use. The combos are DC-300 series older gen combo Optex cameras. Purchased a "few" of these over 10 years ago. Kind of "firesale" like so I purchased the entire "lot" that the vendor was selling. Around the same time bought the vendor's lot of PIR's with pinhole cameras in them.
I don't think they are being sold anymore anywhere these days?
Very well built devices, very discrete and a very nice footprint. Unless you stare at it some you don't even know its a camera.

The newer Optex combo outdoor camera/PIR are not as discrete looking. (kind of has a mobotix look) http://www.optexamer...?l1=2&l2=&id=31

I just wanted better optics and more features so did a "hot" swap of all of the Optex camera boards going to same size boards (except better resolution, optics (going to a 3.6 lens), etc ($200 camera board which I purchased for less than $100 each).
The next update to the Optex camera board will be a major mod/hack as I am adding a network cable to the connection. I am now at the analog limits of the cameras so moving them to IP (still keeping the analog connection though) IE: today there is an RG6, Power and 2 pair alarm cable going to them. With the update adding a network cable to each of them.
