Eclipsing binary systems hold a central position within astrophysics in thatthe fundamental parameters of stars can be determined by direct observations.The simultaneous analyses of high-quality space observations, combined withground-based photometric data, have allowed more sensitive detection offundamental stellar parameters by multicolor photometry. In the paper, thefundamental parameters of the component stars for the V1175 Cas binary systemwere sensitively obtained by a simultaneous analysis of the TransitingExoplanet Survey Satellite (TESS) light curve, and new CCD observations in {\itBVRI} filters obtained with a 60 cm robotic telescope at the TUBITAK NationalObservatory. Following the analysis, the masses and radii of the primary andsecondary binary components were determined as $M_{1}= 1.64\pm 0.04\,M_\odot$,$M_{2}= 1.63\pm0.07\,M_\odot$, and $R_{1}=1.77\pm 0.05\,R_\odot$, $R_{2}=1.77\pm 0.25\,R_\odot$, respectively. Moreover, the distance of V1175 Cas wascomputed as $280\pm32$ pc. The photometric analysis reveals that the componentsof the system are in a similar evolutionary state. The primary and secondarycomponents exhibit nearly the same masses, while their radii are perfectlymatched. Additionally, the ages of the components are also consistent withinthe statistical uncertainties. Consequently, the system's overall age isassessed to be approximately $750\pm70$ Myr.
