Since we are already a tad off topic:
Personally, I layer my security, and it does not stop at the structure.
I also don't make things obvious.
Bsmt windows all have those cheap burgular bars- easily bypassed with a hacksaw or screwdriver, but still there, and still a deterrent. Bsmt windows also have a plexiglass additional window added on the exterior to delay easy break in attempts. (all windows still function/ appear normal)
Some main floor windows not easily viewable by public have those cheap bars (and plexiglass) as well.
All hedges, shrubs are trimmed away/below from windows, giving a open clear view. Rose bushes are also planted with the shrubs, as another deterrent (who the heck wants to get thorned to get near a window??) There is also other plants that are very useful for this application. (and I know its quite common in England, I call them thorn bushes, and they have about a 1.5" spike all over- and hurt)
Alarm- yes. Properly installed, and basically false alarm proof. (no false alarms in over 6 years now) Bright flashing strobe light mounted on the front and REAR of the house, (unnoticeable until activated) along with interior and exterior siren boxes. (also all hidden) Interior siren is of a very loud, uncommon disorienting noise. (in other words, it actually causes nausea, and balance issues and causes a flight or fight response.... And well, you cannot fight what you cannot see.. so... flight is the only other option.)
Locks- Yes, I have good locks, and no, it does not look like fort knox. Only two keyed locks on exterior doors. All locks have nightlatch feature- which is used. Locks appear to be common locks, but with some special internal additions which would lessen the probability of a successful pick. (unless your a member on this site, or squelchtone)
Door frames- Thankfully made out of solid hardwood. Tied in and reinforced to the house frame- including some additional 2x4's to beef it all up. smallest screw used in/around the door and/or frame is 5"- most are 6" and some are 8". Even a few lag bolts thrown in for good measure.
Lighting. I have low voltage lighting in security specific places around the residence where the common street lamp does not cover. Standard outdoor house lighting is also used, with LED bulbs for cost effectiveness, and life span over CFL bulbs, which suck/die in Canadian winters.
CCTV- Is installed, but it not obvious. If you look for it, you will see it, but if your just walking down the street looking, it does not stand out.
One thing to remember, discrete is elite. You don't want to have a place that stands out as this would only bring more attention to your place. (people wondering what you got to lock up in there) My residence does not look any different/more secure/more security than any other on the street.
Cost of all this? Not that much actually:
Locks: $150.00
CCTV: $500.00
Door reinforcement: $ 60.00 each
Plexiglass/burg bars: $200.00 (I got a really good deal)
Alarm- $200.00 with a $120 year monitoring fee. (I own the alarm, and designed the layout)
Lighting: $100.00
Plants: $50.00 in rose bushes. (the shurbs were already there, I just trimmed them)
Looking at those numbers is slightly daunting when its all added up- but remember- this was not all paid out at once, this was done over a 4 year period. I'm sure I will be adding to it in the near future. Also considering on plans for a strong room for my lock collection to display-but this will be when I own property, not just rent.. (appropriate, no?)
When I move, most of the installed equipment comes with me- less the door frame reinforcement. (and some alarm sensors) Thats behind drywall. Basically the stuff I bought thus far is a lifetime investment. (less plexiglass, it has a shelf life thanks to mr sunshine)
Oh and the best security feature? Retired friendly neighbours on BOTH SIDES of my residence. They are the BEST security measure by far. (heck they called me once when my gf dropped by unannounced in a rental car when no one was home- the neighbours called me to warn of a strange car before she even had a chance to dial my number on her cell!)
Thats my two cents on this topic, even thou its slightly off topic.
