Hi, you can determine the resolution of the images yourself. And it also depends on whether something runs in front of your lens. Constant movement triggers a recording.
Without a lock, everyone has free access to the camera settings, batteries and data. Unless you protect the system with a password as described above.

Hello, I can't answer the first question. Our camera has been running continuously for many weeks, so that's not a problem. And secondly, there is a strap on the camera, so you can attach it to trees or pipes or something similar. But there is no safety device.

I only need the camera to take photos. I have a 64 Giga card in it and the camera has been in use in the same place since 4.9.25. As can be seen in photo three, the camera could be secured with a small maggot lock.

Hello, I have 128 GB. Since you only record short videos anyway, less storage space is enough. Anyone can open the device without a padlock. However, you can also enter a password so that nobody can access the system
