According to Paradox website:
1. SP4000 is 4 zones panel with support for doubling. Mean 1 physical input wire become 2 zones. (Total 8 zones).
2. K636 has 1 zone on the keypad. Not sure if support doubling.
3. K636 keypad looks old school. I think the K10H looks better. lol...

Belco price for SP4000 come with K10H, 5x shock sensor, 3x magnetic sensor. RM700
1 shock sensor = RM8
1 magnetic sensor =RM4.50

I think KedaiCCTV dare throw price coz they will most likely charge for after sales service (when they visit your house). If do lousy job, they keep coming back, have to pay again and again?
If do good job, then can have a peace of mind.

It really goes down to picking a good installer whom may charge a bit more, but can do proper job and after sales service. If after sales service jialat, call Paradox distributor to complain about installer?
