Kallos tapped his discretionary funds to buy five security cameras for the northern blocks — each with a live 24/7 feed to the 17th Precinct — and Powers dipped into his Council funds to purchase two more for the culs-de-sac as far south as Beekman Place and 50th Street.

They don’t come cheap: Each camera will cost $35,000 for an overall tab of $245,000. It wasn’t immediately clear when they will be installed.

“Soon, the 17th Precinct will have eyes on the park — and it will be able to respond instantaneously and even proactively,” Kallos said in an Aug. 3 press conference at the river-facing dead end on East 54th Street.
