We report the experimental setup and overall results of the AARTFAAC wide-field radio survey, which consists of observing the sky within 50 deg of Zenith with a bandwidth of 3.2 MHz at a cadence of 1 s, for 545 h. This yielded nearly 4 million snapshots, two per second, of on average 4800 square degrees and a sensitivity of around 60 Jy. We find two populations of transient events, one originating from PSR B0950+08 and one from strong ionospheric lensing events, as well as a possible single extragalactic transient. We also set a strong upper limit of 1.1 all-sky per day to the rate of any other populations of fast, bright transients. Lastly, we constrain some previously detected types of transient source by comparing our detections and limits with other low-frequency radio transient surveys.
