The woman’s children, aged 15, 16, 18 and 21, were removed from the house in Handsworth as locals watched on.
Officers swooped on the property in Pretoria Road, Bordesley Green, at around midday.
A number of officers, police dogs and a force helicopter can clearly be seen in the video.
West Midlands Police later revealed they were acting on a tip-off, adding they were working with “good intent”.
The youngsters were lined up in the road covered by officers with machine-guns, forced to lie down and handcuffed.
She said: "They were absolutely petrified and hadn't got a clue what was going on. To think they were led into the road like criminals breaks my heart.
"They are in shock at the moment and are receiving support from our wider family.
"The police broke the fence at the bottom of my garden, left my home a mess and haven't even had the decency to apologise."
The mum said she believes the call was "malicious", but said she has "no idea" who could have made it.
