I would highly recommend multi-tenant properties to have such a system. But I would never recommend my supplier... in fact, I would tell everyone not to use my supplier. Typically the basic system costs about RM500 for each door, including installation. So, at that time I found a supplier who advertised extensively in the newspaper called SECUROF. They were at least RM100 cheaper than their competitors. But what I didn't realize was the maintenance costs. Typically access controllers don't fail. It is a very simple logic board with buttons. However, this supplier used very low quality cables. Just after the initial 1-year warranty ended, the system failed. We couldn't lock our doors. This happened to all the 4 properties that I installed this system although they failed a few weeks apart from each other.
SECUROF charges a very high on-site visit rate which is RM150. Each time you call them, they will charge you RM150. So, the 1st round they came and the technician showed me the metal inside cable practically disintegrated. It has become powder! I got charged to replace the cable. But that's not the end of it..... Throughout the next 1 year, I had to call them out a few more times because each part of the 4 to 5 sections of cable began to fail. 1st it was the main source, then it was the push button, the battery pack etc etc... So, the cost of a RM500 system suddenly became almost RM1000! And I can tell you every single one that I installed had the same problem. SECUROF blamed their installation contractor but I told them they should not charge me the visit fees because all it seems to me, that's how they make their money.
I don't think I have defamed SECUROF in this case as I am just relating to all of you my exact experience. As a consumer, in Malaysia we have little rights, the only thing I can do is to warn others to be more careful. If you choose other suppliers, ask them lots of questions about the cables that they use and also cost of the spare parts after warranty.
