How much should our condo be spending on building security?

My HOA in Massachusetts recently started installing new camera surveillance system without owner approval. Can we stop them?

Can HOA make me remove my fence?

Our security gate needs to be repaired.  The board want to just take it down. Do security gates increase property values or decrease insurance costs?

Security concerns about lost key to condo building and trespassing. Who is responsible?

Can condo associations and HOAs ban ring doorbells from recording conversations

Lately we have had non-residents somehow entering our condo building.  What can we do to prevent this?

Security - Doorbells and buzzers. We recently installed 4 new panels with 6 units per panel totaling 24 units. Each doorbell has a space for a label by it.

Someone suggested Ring by Amazon for my front door security. I can see if from my iphone and I was told its easy to install. Has anyone had experience with it? Or is there a better choice?

Does anyone have video surveillance rules/guidelines that you could share with us? We're putting in video at our pool & tennis courts and would like to see what others have formulated as guidelines, SOP, etc. Thank you in advance for your assistance.
