Telescopic meteors are just meteors seen through a telescope or binocular. That is irrespective that some are sufficiently luminous to be visible to the unaided eye. Most are the result of micro-meteoroids with masses in the range 10-4 to 10-10kg. They are exceedingly numerous. They make up the bulk of the meteor particles entering Earth's atmosphere. For example, the hourly rate of +9m meteors is about 10000.
Through the small field of a telescope or binocular only a minute fraction of these will be seen. An experienced observer using a suitable instrument, will see typically 6 to 8 sporadic meteors per hour. That's only a little less frequent than for a visual watcher would expect. That rate may seem surpringly high based upon common experience. Most telescopes are used with magnifications which are too high, and fields which are too small to capture meteors. Even where this is not the case, you would be correct that rates are still lower than 6 to 8. Casual meteor sightings, even with suitable low-power, wide-field instrument, for example while comet hunting or looking at deep-sky objects, only yields rates of about 1 or 2 per hour. Actively looking for meteors makes a big difference.
The majority of telescopic meteors are sporadic. This is even true during major showers. The prominent visual showers have relatively fewer meteors than the sporadics progressively to fainter magnitudes. Showers giving peak activity greater than the sporadic rate are not too common. One noteable one was the alpha-Lyrids of mid-July, which in 1957 had a peak about three times the sporadic background. The Geminid shower is probably the most active currently giving rates comparable to the sporadic background. Contrast that with visual observations where the best regular showers are about ten times more numerous than sporadics.
