It is typical and expected to see and capture non-Perseid meteors in these types of shots. In addition to the Perseids, there were also meteors coming from the North delta Aquarids, South delta Aquarids, South Iota Aquarids, Piscis Austrinids, alpha Capricornids and sigma Capricornids, kappa Cygnids, all active on the same night. And those are just the active pre-identified showers with radiant points named and located on the Starwalk app; there are also sporadic meteors, with no named radiant.
On the second best night of the 2021 Perseid meteor shower, one night before peak, we had some luck in this location in Nevada, despite some wildfire smoke. This is a composite of a dozen of the brighter meteors.
