Moving new business into an industrial unit. Will be valuable machinery (large, heavy, harder to move/steal) and inventory (easy to move/steal) on site we want to protect. Area is a fairly remote industrial area, not alot of people around. Not much criminal activity I'm aware of but also nobody around if a criminal wanted to get in at night, and response time of police once notified is probably 15-30 minutes I'm guessing (I will find out further).
Three potential points of entry to bad guys (from right to left in the following photos):
- Windows on right-side garage bay doors (two sets of identical retracting bay doors both with windows)
- Centre solid door going into the industrial area (has a small window with embedded wire)
- Left-side door goes into a small office and then through another door (no lock) into industrial area

The windows on the garage bay doors are protected by some metal rods installed on the inside of the doors. Pretty flimsy, I feel like I could bend or rip them off with bare hands or maybe some simple tools. Glass is just single pane, someone could break easily.



Central door has metal frame, feels sturdy. The lower half of the frame is connected to concrete on the left and right sides, upper half and above are corrugated metal, all looks and feels pretty strong but what do I know. There is an upper Schlage deadbolt and a lower Dorex key/handle (the Dorex says UL and F on it, don't know what that means in terms of certification).
You will see from the image of the front of the door there is a wire-glass window. Also note there is a large gap between the door and the frame, almost a centimeter wide, so you can actually see the deadbolt and keybolt going into the frame, I assume that's a security risk?
Also, there are three hinges on the outside of this door, took photo of one for example, I read somewhere this may be a big security risk, better to have a door with hinges inside?







Lastly, the glass door. There is alot of glass with the door and surrounding windows looking into office area. Luckily the windows are tinted quite dark but not 100%, hard to see in, easy to see out.
They key mechanism says "Adams Rite - Assa Abloy".
Door has two hinges at top and bottom of the door, took photo of one. Is this a risk also?




Questions:
- Are these deadbolts / key-handle mechanisms decent?
- Are the outside hinges on the doors a big problem? Do I need to replace doors with inside-hinge versions?
- Any ideas on most cost-efficient way to protect the glass door and surrounding glass windows? Is it cheaper to install bars on windows inside or replace windows more break-resistant versions, I'm guessing the former?
- Are these metal frames good enough?
- What about the gap between door and frame for the centre door?
- Is the wire-embedded window in the centre door a big risk? If I had to replace the whole door I would probably go for a solid door with peephole instead
- How about protecting the garage bay door windows?
Any ideas would be appreciated.
Budget say couple hundred dollars, but could go up to $1,000 if necessary
Thank you
