Backdoor Protection, How does it work ?
As the title says, how does it work exactly. I know that it is supposed to give your buildings regen in no creeps nearby but it doesn't seem to work like that always. Some times even when there are no creeps nearby you can take out a tower or barracks without BD protection coming into play.

So, can anyone shed some info about it ?

All buildings except for the Tier 1 Towers possess the passive ability backdoor protection. Backdoor protection activates when there are no nearby enemy creeps, and causes the building to take 25% damage from illusions and 75% damage from other units. If a backdoor-protected building is damaged by an enemy, it will regenerate the lost health at a rate of 90 HP per second. It is still possible to destroy protected buildings with sufficiently high damage. Backdoor protection will not regenerate damage dealt by friendly units.
On the Tier 2 Towers, backdoor protection is independent for each tower. The faction base applies backdoor protection as one single unit, e.g. if there are enemy creeps near one Tier 3 Tower, all the other Tier 3 towers and barracks will drop their backdoor protection as well.

Is there a known value on the radius ?

Also do creeps controlled by your character counts ? or does it have to be the lane creeps ?

Backdoor protection activates when there are no enemy team creeps within a 900 radius of the tower.
As for your second question it looks like you could before it was patched out.

it also said "Once deactivated, it takes some time for the protection to activate again."
So, if I do this:
- I attack Ancient with BD protection only once (meaning 1 hit)
- Waiting for the aura gone
- I attack the Ancient once again

Does it still have BD protection ?

Lets says if I already destroy both of Mid Rax. What is the minimum distance of the creeps to disable the BD protection ?
