Would like to draw experience from those who have experience living in condominiums or apartments particularly high floor units. It is quite a norm to install iron grille at the main door and the small balcony area at the air well just outside the kitchen of condominiums or apartments. However, it is necessary to install iron grilles at the main door of the balcony at the living room and the windows of the bedroom that are all located at the facade of the building? For the burglar to enter through these doors or windows he/she would need to be like a spiderman just like the infamous Frenchman (forgotten the name) who used to scale tall skyscrapers using his bare hands including the Petronas Twin Towers before getting caught by the authorities or police.

Back to some seriousness, are there any owners living on condo units who have had someone breaking into your units? If yes, where is the access point that the unwelcome visitors use in gaining entry into your units? Is it through the main front door, the air well area through the kitchen or, just like Spiderman, through the balcony area or windows of the building? Do you have iron grilles installed at all these areas prior to the uninvited visitors gaining access into your units?

Any experience would be appreciated.

Didn't see your post coming in when I replied to the earlier post. Yes I agree it is a good assurance to install these iron grilles as there is just a full sliding glass door at the main balcony area. Just trying to see if there is anyone who has had their units broken into through this access at the high floors, with or without iron grille.

As for the main door, similarly I would think that iron grille and padlock is the way to go. However as I have mentioned earlier, even if there is an iron grille or solid padlock, an experienced locksmith will be able to open the padlock within seconds. Having said that, the iron grille and padlock at the main door will still be useful as a form of assurance.

Is the CCTV inside the apartment or outside? If outside, is there a power socket to power the CCTV?

Similarly I plan to install a CCTV in the apartment, though a cheap one such as the Xiaomi Dafang. However, I was thinking that even though there are all these security measures in place, the thief or burglar may have got smarter throughout the years with all these technological advancements. Even though there is a CCTV, the intruder may wear a face mask and for this reason people may not be able to identify the culprit. I have received few Whatsapp videos from friends and some of the break-ins captured by videos, the intruders were wearing a mask or a cloth to cover the face.

Similarly I am in agreement with few comments on iron grille. It is surely true that the padlock, I mean any padlocks low-end or high-end can be easily opened by a locksmith in several seconds. Few years ago I hired a locksmith to open a padlock and to my amazement he opened it in a blink of an eye, probably in less than 5 seconds. It's like child play to him. Seeing him unlock the padlock just makes me wonder the man can enter through any locked gates without any problem. Though he is earning a living but with the skills he possesses, he can have access to basically any home if he has bad intentions.

Now coming back to this iron grille. If the main door iron grille and padlocks are breached by the intruder, the second tier would be the CCTV and most importantly alarm. Personally I think CCTV is important but it is just a tool to record videos. That's all. It will likely not prevent the thief from carrying out his work. However, the alarm will surely cause some panic and somehow disrupt the activity. Better still if the alarm is connected to the main security system of the condominium or apartment so that the security guards will be alerted once the alarm goes off, but this connected system is usually available only in high-end condo or apartment.

In summary, it is clear from this thread that iron grille is necessary for high floor condo units, not only for break-ins but to prevent a young child from falling 10 or 20 storeys down. The second point is if the 1st tier security in iron grille at the main door or pad locks are breached, the 2nd tier security which I believe is the last tier will be the CCTV + Alarm.
