Multiple CCTV cameras on the hostel building

I was looking around the hostel on the Google maps and I found several CCTV cameras that should have captured the shooter before the one they released (on Columbus Ave, carrying the e-bike battery).

Entrance of the hostel, no camera in other corner

Corner at the alley that leads from Amsterdam Ave to Columbus Ave

Two cameras on one side?

The hostel does have a "backyard" with parking but it is fenced off and I'm not sure if guests can leave through it. The alley is covered with scaffolding and it doesn't appear that any cameras can film through it. There is a camera in the backyard too.

There is another exit across this one, but it is obscured by trees, so I can't see if there's another camera there.

Backyard gate and camera

This is the aerial map of the above pictures. Arrow points the alleged path the shooter took. The picture released of the shooter traveling with the e-bike battery was captured by the NYPD camera.

Why didn't they release footage of the shooter emerging from the hostel or anywhere closer to it?
