This adorable video showing two US kids talk to their working dad through a security camera as they enter home has blown up on TikTok.

Five-year-old Jameson and Griffen, who is almost two-years-old, have been greeting their dad like this for almost a year now.

Their mum Candace told Newsflare: "It happens more frequently now that the baby can talk also. They do it daily.

"My husband is gone for weeks at a time for work so my kids do it every day so he can see them. It’s hard on them to have their dad gone all the time."

My husband travels for a living, so my kids have made it a habit to say “hi dada” to our security system every time we get home.

My kids are Jameson, 5 and Griffen, almost 2. It’s been going on for almost a year now, but more frequently now that the baby can talk also. They do it daily.
