Jeffrey Brennan from Sentry Security Systems Inc., in Havertown, Pennsylvania is not to be trusted.  He kept my cash deposit of $4000, and did not follow through with our previously agreed upon contract. When I won a judgment against him for not following through with the contract, he wrote a check from his Federal Credit Union in front of Judge Elisa C. Lacianca, it bounced, and I collected nothing. You work too hard for your money to be conned by this unscrupulous individual.
