We present narrow band photometric reverberation mapping time-delays for three nearby active galactic nuclei (AGN). Using the Stella robotic observatory we obtain continuum and emission line light curves for NGC 3227, NGC 4051 and NGC 4151. The continuum is measured through the broad Joohnson-Cusin \(V\) band and the H\(\beta\) emission line through the narrow \(hbw\) band. We find time-delays for NGC 3227 of \(X.X^{+0.0}_{-0.0}\) days, NGC 4051 of \(4.5^{+2.6}_{-1.0}\) days and NGC 4151 of \(11.8^{+3.2}_{-2.9}\) days. In addition to time-delays we measure absolute luminosities and add these new measurements to radius-luminosity relation for AGN. The results are in good agreement with previous studies, and demonstrate that accurate AGN broad emission line time delays can be obtained using narrow band photometry and short exposures on smaller telescopes. Future reverberation mapping surveys for measuring AGN time delays may save significant observation time by applying photometric reverberation mapping.
