Can you not run the Hikvision's in hallway mode? They should support it, depending on firmware.
Also: what's in the hallway? Do you need every inch covered or just key points in it?
David, why would higher or lower end cameras make a difference in a hallway specifically? Is there some specific feature tradeoff?
Here are 240+ cameras that support corridor mode. Btw, are you using Avigilon's VMS? How else are you going to get their cameras to do hallway / corridor mode otherwise?
The bigger question for those 2 options would be does the customer want to do pixel search on these hallways or can they get away with just doing a regular search to pull video as the hik cameras cant do pixel in avigilon but the avigilon camera can obviously. But the Hikvision cameras do work well with Avigilon, I have a system I am putting in next week with 11 of the turrent style cameras (3mp 4mm) using Avigilon ACC5 for an industrial client that was on a tight budget and we gave them both options on cameras and they picked hik
I don't get why Avigilon would need specific support for hallway mode... I've been doing it for a couple years now with both Dahua and Axis cameras on Vigil recorders, I just use the function in the camera to rotate the image 90 degrees, and Vigil sees and records it as it would any other stream, it's just tall and narrow - 1080 x 1920 rather than 1920 x 1080, for example.
One thing with hallways, unless there are a lot of side doors you need to cover, you should generally be able to get away with one camera at either end - you should have good enough image to see what happened along the length of it, and anyone in there will have to pass the camera to get out. 250' long, you may need to add one or two spaced along the length of it just to fill in, but identifying people shouldn't require massive coverage, you just need to get them at the choke points.

Just my opinion, but I would look into staggering 180 degree wall mounted panoramics, similar to this:
We have tried to make 360 and 180 cameras work in school hallway applications but it never results in a good solution so we always go with 2mp recessed domes in the drop ceiling and turn the image 90degrees(hallway mode) to get the best result -- 2mp is the best because of the 16:9 aspect ratio so you can flip it and get the best result just be aware of ceiling mounted exit signs and soffits when doing your walk-through design as those can get in the way of the best shot - good luck
You do get top of heads when they are directly under the camera but they are walkign down the hall so at most points you have a face shots so they can id students for incidents very easy
I see a lot of installations where the cameras are at both end of the halls. Although the camera at one end may be able to see the door at the other end, the long distance may not yield a very clear view. Try ceiling or wall mounted cameras directed toward each other (more toward the middle of the hall). This should cut the distance to target and minimize blind spots (i.e. under the cameras). You may be able to cut the number of cameras as well.
We have used the Mobotix Dual dome technologies for hallways for many years. It is not a cheap solution but if you factor in less network drops, less install labor, less VMS licensing it is an attractive option. I've been asking other camera manufacturers for years to provide another dual dome option but for some reason they resist or perhaps the request never reaches the right ears. Or maybe we are on an island liking this solution. The quad sensor options are overkill for hallways in my opinion.
