We present the results of a deep near-infrared (NIR) imaging survey searching for very low mass young stellar objects (YSOs) in the embedded cluster associated with the Perseus molecular cloud. Our observations cover an area of ~5'x5' in the NGC 1333-S region at J-, H-, and Ks-bands. The 10{sigma} limiting magnitudes exceed 18mag in all three bands. Based on NIR color-color diagrams, embedded YSO candidates were identified using NIR excesses.
