Security Cameras Systems

Installing the cameras, sensors, wires, etc and then connecting it all to a main computer and then set up the wireless alerting devices - notifying you and then the police department? Is this a difficult project but worthwhile since there is no need for a monthly fee that you pay with other security systems?

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.

I already have an alarm system at home. Should I still install a home security camera?

Recently moved in to a newly built home in a rural area, right next to a busy road.

Recently I’ve noticed weirdos stopping in front of my home and taking photographs of my property. When I go outside to let them know I can see them, they take off.

At nights, there are strange cars parked on the road with their headlights on near my home.

I have expensive new cars parked on my property so I am thinking they are planning to carjack them or rob my home.

So far I’ve:

Installed a fence around the property.
Got a large dog that bark at strangers and will bite if they happen to jump the fence

Which is the best wireless security camera that works in the total darkness (there are no street lights here) and that can be broadcast on the Internet?

I have a chain linked fence only, so what can I do so they can’t see throught it?

Any other ideas?

Which is better? Alarm Systems or Home Security Camera Systems?
