Abstract : Active Galactic Nuclei (AGN) are distant, luminous and compact, and it is not possible to resolve spatially their central engine by current and future technology. However their variable nature, and the echo of the continuum radiation from their different component, in conjunction to the high temporal resolution, has allowed us to decipher the great amount of details to understand the structure and emission mechanism of the AGN as well as to estimate the Black Hole mass of Central Engine of AGN. In this context, we will highlight the importance of 1-2 meter class telescopes firstly based on our past and ongoing monitoring for various sub-classes of AGNs using 1-2m class telescopes in India. Secondly, we will summarize our few key programmes based on statistically large samples of archival photometric data such as of ZTF, to probe the emission mechanism and environment of the Central Engine of different types of AGNs.
