Hi Maggie
Regarding your question, I have installed approximatly 70 sets of electronic shutters on the CDS site, at present to the best of my knowledge, NOBODY has gained access to ANY apartment via electric shutters that I have installed, there has been some attempts but to no avail as they are motorised, I admit one set has been damaged but the apartment was still not accessed, and they were repaired immediately, of course a fee was incurred.
Window and Patio door bars are popping up over the CDS site and are coming in various colours and designs, it is up to Presidents to keep the Urbanisation into some sort uniformity.
I would suggest you also consider installing window locks as this seems to be the only point of entry for the burgulars, especially via the bedroom windows.
Please feel free to contact me for any further advice.
