Inter-Stellar meteors?

I have an automated meteor detection camera. It works fine, but few times I have detected possible meteors that enter Earths atmosphere at very high speed. The software I’m using classifies anything with velocity over 72km/sec as flash and takes just snapshot of such an event, not the movie as it does with slower moving objects. It is reasonable to expect that inter-stellar object may enter Earths atmosphere faster then 72km/sec limit imposed on solar system meteors by solar system escape velocity and the Earths orbital speed.
Question. Do you think that inter- stellar objects hit the Earth occasionally, at what speed and is there any evidence of it?

Image of very fast object burning in the atmosphere. It is not any kind of electrical discharge – too straight for that. It is not reflection of light from an insect flying close to camera lens, again too straight for that. Laser pointer beam, possible but unlikely that someone would streak beam across the sky just once and switch it on and off in 0.08 sec. Exposure time of this image is 0.08sec.
