Recommendations for 2.8mm 4MP Cameras for a New Install - Interior Hallways - Wall Mounted

[Bionic]

I'm planning a new security camera install and could use some recommendations for a specific setup. I'll include a photo of the floor plan, highlighting where I intend to mount 3 cameras.

Requirements:

• Camera Type: 2.8mm, at least 4MP
• Power: POE 802.3af
• Audio: Built-in microphone
• Location: Hallway B & Hallway E (3 cameras total)
• Mounting: Wall Mounted. Ceilings are around 13 feet high, but I'll mount the cameras on the walls at about 8 feet. I'm looking to direct mount these without using any additional wall mount accessories. Similar to how this turret camera on the bottom left is mounted in this photo.
• Aesthetics: All cables will be hidden inside the walls, unlike the example photo I'll provide, which shows a turret-style camera mounted vertically on a wall with exposed cables.

I'm using BlueIris for the NVR, so compatibility is a must. If anyone has experience with a setup like this, I'd love to hear your thoughts. Any specific features I should be sure the camera incorporates? Since this is a hallway, I am not sure if I need the AI stuff. Any specific models or brands that you’ve had good experiences with?

Thanks in advance!
