I have an old brinks bhs-4000a system in my house and I was think of taking that out and put a system in where i can hook up all the door/window/PIRS/smokes/ etc. up and then hook up relays to lights, A/C, mag locks, dorr latches and other devices to turn on and off. I would also like to get a mic and speaker to do 2 way and ptz cameras and record temperature or if there is flooding (inputs that are digital for sure but analog would be nice but analog is NOT a must). I want a system that can hook up to my computer or the network/internet so I can control devices via the web and get text messages (or emails about troubles and alarms) and have many zones like 40 to 100.
What would be the best way to do this? What brands and products would work best? Cheaper the better but I do under stand that I may have to pay $$$ to get what I want. I'm an experienced electrician and just started in the electronics systems industry. I can program about anything (may take me some time but I'm a fast learner and can figure out about anything (with some help of people I know))
Thanks in advance.
