Where do you find one for purchase?
Not sure if you're posing this question to me?
But, purchased four units from one of the on line vendors on blow out sale for $95.XX each. Three came with the L30 (cylinder) lens and the forth came with the L20 flush mount lens assembly. All of them are the older generation (2 MP) which I believe were EOL as they transitioned to the newer 2 MP sensor a few years ago. I purchased these specifically as they used the newer style of RJ11 cable vs what I believe was some kind of barrel style?!?
I've been waiting for the ground to thaw out and build a brick wall under the front bay window as a combination flower bed, accent lighting, and this bird house. Three cameras will be installed in the bird house all with different lens from 1/1.8", 1/2.5", with 2.8 ~ 6.0 mm focal length and settings for Day Only, Auto, IR Only. The Day Only (1/1,8" will offer full time night time color)
The Auto camera will be one of the Bi-Spectrum dome cameras which will transition from Day to Night if required . . . The thermal will pick up what ever this camera can't see in Day vs Night using IR. The IR only camera will be scheduled from a very specific window of time to remain in IR mode. As this spot is very difficult to render good video as the environment has a whole bunch of artificial, natural, lighting that's been hard to dial in for just a single camera.
Right now, I'm waiting for 1000 foot reel of CAT6A Direct Burial double shielded cable, four sets of armored 300' of 50/125 OM3 Multimode LC / LC optical cable, and two GB 6 port POE+ / SFP hardened switches. Had to break down and buy a mattock pick as I'll need to trench all told 900+ feet of conduit / cable.
All of these ground mounted cameras will be running on a completely dedicated (isolated) PtP solar powered network that was put into production last year. Obviously given the massive runs fiber / shield CAT6A was the only choice to guard against electrical surges and lightning (induced EMF).
Still waiting this bird house to arrive and will need to see what has to be done to winterize the entire housing so it doesn't crumble and explode in the Canadian Arctic weather!
Trenching in clay is truly back breaking especially if you need to be at 24" in depth while the ground is frozen solid like steel.
