I've been browsing through the threads and really don't know where to start with home security systems. I just bought my house and installed multiple cameras and am looking for a security system that I can install.
Any recommendations?
Personally I am a fan of the Honeywell/Ademco Vista Series 15p or 20p. These are tried and true systems that have been out for a long time and are simple to install and program if you have basic electronics understanding. However, since this isn't new construction you may not want to spend the time hard wiring all your sensors so you may want to consider wireless. Be aware both these systems do have wireless modules available but you still will need to install the main box/panel, battery, controller board etc somewhere and hardwire one panel at the very minimum.
If you want to go with a wireless system look at the Honeywell/Ademco Lynx systems - it doesn't get more straight forward than these systems. The main unit/touch panel houses all the brains and the sensors simply link back to it. All you have to do is plug that touch panel in and you are ready to go. They have options for wifi adapters, GSM cell dialers, Ethernet comm modules all for monitoring if you want it monitored by an outside service (Alarm Relay is one of the more popular ones).
Also note that the majority of Honeywell/Ademco hardware will support Alarmnet which is the remote access/app you can access remotly via internet/phone and setup rules/alerts - so if you do get a monitoring company make sure they are alarmnet supported/certified. Also assure any monitoring company you go with is UL listed and certified. You will not be able to access alarmnet yourself or use the app unless you pay for monitoring - just as FYI.
Regardless don't get hung up on Sensors - some people go CRAZY with sensors.
Assure you have 1 keypad at the main entry, consider a second for the bedroom or another door if you have two heavily used entries.
Have contacts on your entry exit doors.
Utilize a few motion sensors on the main floor and or basement to cover the majority of your main living areas or areas where a window may be used as an entry point. To many times I see people pay for 12 window sensors or something crazy, when 2 motion detectors will do the trick. Sure a window sensor will assure an alarm sounds as soon as the window is opened, but a motion sensor will get someone as soon as they poke there head into the window. This will also allow you to arm the system and leave some windows open during the summer with out having to go into a "bypass" for that sensor prior to arming.
My personal opinion is glass breaks are over rated - I've seen to many false triggers with them, I'm not a fan.
Even though you have smoke detectors already, consider getting at least 1 smoke/co2 combo units for each floor that connect to the alarm.
Hope this helps some or at least will get you started in some research!
