I'm going to start by saying that I'm NOT a professional installer or reseller.
I'm just a homeowner that has researched and built my own system with the help of information that I found here.
I'm not an expert, nor do I play one on TV. At the same time, I figured it wouldn't hurt to provide some of the thinking behind my choice of a wedge camera as part of my overall camera system.
I'm planning on using a Starlight wedge dome right next to my front door at eye level. I'm using an exiting hole, where a really old video intercom was mounted. There is more than enough light on the porch that I'm planning on turning the IR Off completely. I agree that there could be IR issues with a dome outside unprotected, And I agree that external illumination is a better way to go if you do use on outside. I don't agree that a turret is a better option for every situation though. Turrets are quite a bit bigger than the wedge cam with the small dome. The starlight sensor and the specs are the same as the turret so the performance should be similar.
The way I look at it, the Wedge that I'm putting in at my front door fits MY specific needs better than any of the other options.
- It's a supplemental camera to begin with. To get there you have to pass at least 2 other cameras. So I'm going to know you are there way before you get to the dome.
- Its mounted well back on my porch, so sun glare on the dome is a non issue.
- The layout of the porch is funneling you right to the camera, so I'm not dependent on high PPI at a long range.
- You are going to be 10' or less from the cam, which gives me well over 100ppi anyways.
- It's a starlight, so I can run it without IR and still make a decent ID even if the porch light isn't on.
- And its got a smaller footprint, so its less noticeable on my porch where it needs to be mounted. I can tell you that with the size of the turrets, mounting one at eye level next to the front door would not fly with the wife. (And she is fine with the other 11 cams I have up.) I want to cover the house as fully as possible, but I'd also like it to blend in a bit if at all possible. The wedge at a quick glance almost looks like a doorbell camera, the turret looks like a giant security camera.
These little wedge cameras should not be the first choice for your main camera locations outside. I agree that the primary layer of camera coverage would be better suited to the starlight turrets. These little wedges DO have ligitimate uses outside though. And since its an IP67 rated unit, I can only assume that Dahua figured that it would be used outside at times.
The bottom line is we each have to figure out what our specific needs are. And we have to choose equipment to meet those needs, whatever they are.
I figure that it really doesn't matter if there is a "Better" option available if that better option never gets installed because its too big, the wife hates it, or it just doesn't fit the desired location. I see it with clients all the time in my job. There is a piece of equipment that would be perfect for their needs, and they don't approve it for any number of reasons. Sometimes we need to find a product that's right for the specific situation, not the best product overall.
