It depends on the specific situation and purpose. A camera is typically used to capture images or videos, while a dummy is a replica or imitation used for various purposes such as training, testing, or display.

However, if the intention is to simulate a scenario or provide a physical representation without the functionality of a real object, a dummy may be more suitable. **

Above your rental apartment door, there may be a door frame or lintel, which is a horizontal beam that supports the structure above the door opening. There may also be a transom window, which is a small window above the door that allows natural light to enter the space. Additionally, there could be a decorative molding or trim, such as a crown molding or a decorative pediment, to add visual interest to the doorway. **

To build a round arch for a wooden door leaf, you will need to first create a template of the desired arch shape using a flexible material like cardboard or hardboard. Next, transfer the template onto the wooden door leaf and carefully cut along the outline using a jigsaw or a bandsaw. Sand the edges smooth and apply a finish to the wood to protect it from moisture and wear. Finally, install the wooden door leaf with the round arch into the door frame using appropriate hinges and hardware. **

If the door lock of an old door in a rental apartment is not functional, you can try a few things to make it work. First, try lubricating the lock with a silicone-based lubricant to see if that helps it turn more smoothly. If that doesn't work, you may need to tighten or adjust the screws and hardware on the door to ensure that the lock is properly aligned. If these steps don't work, it's best to contact the landlord or property manager to have a professional locksmith come and repair or replace the lock. **

Additionally, there may be additional costs for any necessary permits, materials, and finishing touches. It's best to consult with a contractor for a specific cost estimate for your particular project. **
