text: kal raat jab main soyi thi,mujhe laga kisi ne ghar ka doorknob touch kiya, soch rahi hoon ki ek smart doorbell install kar doon, kya tumhe yeh idea acha lagta hai?definitely, smart doorbell se hum kisi bhi visitor ko dekh sakte hain aur bina khulte hi jaan sakte hain ki koi hai ya nahi, bahut convenient hoga!
