Beyond the sole usage of blocking at least one of the two vents, alongside blocking the ability for Vents to be disabled, it is possible to beat Sadmin Night cameraless to 6 AM.
Theoretically, it may be possible for Yes Face to always target disabling the Ventilation System - thus avoiding camera usage entirely, but the odds are very unlikely.
For anyone needing to know how the three main threats work:
Sadmin will roam around on the ground, appearing between Cameras 1-5, and occasionally appearing at your door. On Cam 2, he will either head straight to your door, disabling it in the process, or go to Cam 1, and disable your cameras.
Yes Face will sleep, but once awake, will head up to the vent cameras (6-8). If he's on Cam 6 or 8, he will attempt to reach your office, requiring the respective vent to be blocked, else resulting in a instant loss. If he targets Cam 7, he will attack the Ventilation System, requiring it to be repaired in order to block any vents. Once repaired, your previously locked vent will be unlocked, requiring it to be unlocked again.
G-Poo does nothing until 3 AM. At 3 AM, similar to FNAF 1 Foxy, will go through several phases, before charging to Cam 3, where your front door is. In order to stop him from destroying your Maintenance Panel (and eventually you), you need to stare at him when he's at your front window for the Poo to back off. Closing the door will not save you.
There's also the Cryptid, but it cannot hurt you in any way, solely acting as a distraction if you mind its existence. In my experience, you'll almost always encounter it at least once, possibly twice in a single night.
If I missed anything important for further questions, please let me know in the comments.

It feels so surreal to me how much effort and analysis you've put in for a game that was designed to be a joke, but I love it haha. Nice work

Even for games made as a joke, there's always something to appreciate or look into. I was originally trying to see how high I could keep my power by the end of the night (wanting to give myself a harder challenge), but I thought about seeing if I only had to use cams a single time, and turns out it was possible. There's always something new to try, and if not, a second look can bring in new ideas after a break.
