Personally I'm looking at Hikvision and AJAX system. For a terrace house, it's about 3-4k for Hikvision, 5-6k for AJAX, both DIY, the vendors are charging too much for installation and a big margin over every devices.

If hikvision, will be a combination of Lazada + Taobao.

If Ajax, cheaper to ship directly from EU, but of coz I've not tried the website, so there's risk involved.

is this based on personal exp? care to share?

My renovation will start end of this year, I'm just at the stage of deciding which company to go with. I think wireless system is matured enough, definitely more expensive than wired option, but can do away with all the messy wiring.

I will probably get AJAX, seems like the easiest option to DIY, unfortunately the most expensive. One of the HK's official distributor I've contacted is using AJAX for their own office, and they have good review for AJAX.

In terms of security, AJAX a lot more convincing, as they are more like a tech company as compared to the other older brand which started out as security company and now ventured into tech to keep up with time. These company normally know nth about cyber security, but they offered things like remote access via app and stuff, i am not very convinced they know what they are doing.

Not thinking that wireless is better, just hoping that it's a decent choice. No way that wireless can be more stable than wireless right. My CCTV i've sourced it myself, I buy Reolink directly from their website. Again, because the installation is a bit brainless so I source myself.

For ajax:
1. battery is built in the hub, can provide up to 16 hours, only concern is how long can the battery last in useful life span over many years
2. don't know about 433 mhz interference
3. True, but will get notified if any devices drop from the hub, and for battery, will get notification to change the battery when low batt, so should not be a problem, just troublesome for some
4. For commercial maybe lacking la, but for residential, mostly we need door contact sensor, and a few more other sensor like motion, glass break etc. If you look at AJAX, their product line quite comprehensive: https://ajax.systems/products/
5. In fact this is 1 big reason why i did not go with wired option. To upgrade or add sensor, you need to worried about wiring issues. Whereby for wireless option, you simple buy or replace your devices and you can easily DIY

Why don't you go for a mixed option? Can older brand like blugard, paradox allow wired + wireless option? You just need to replace the controller and sensors that are wired, then add more wireless sensors you needed where there's no wire.

HK, Dahua, Tuya, everything is china product. But again, HK and Dahua is both the world leader in this industry.

Ethernet cable can transmit power and data. All the new IP cameras are POE (power over ethernet) so nth new about this already. But for your case i think you are using analog which is diff.

I think it's outdated. They make new analog product probably just to cater to certain big corporate client, but it's pretty obvious that the main focus is IP camera. Yes, it's true to say they will continue to support analog for many years, but you probably wont get all the new improvement and technology lo.

Just like car, still got manual, but most of the manual is just the basic spec, you want all the high tech feature you go buy the top spec auto one lo. Will manual go away anytime soon? nope, not at all, manual will be there forever and ever. but your choice is limited and will get worst.

I just bought my AJAX system, 1 hub, 2 key fob, 1 keypad, 7 door magnet, 1 motion sensor, 1 indoor siren, 1 outdoor siren for 3.7k++. For your reference.

AJAX is wireless. For wired option, why dont you just message the company directly they will refer you to a local partner near you and they can advise.

No, just the price of equipment. I planned to DIY, since it's wireless, all the sensor you kinda just need to stick to the wall, for siren, i'll just get the renovation company to help me with the wiring. The hub just plug and play kinda. I watched some of the video of the AJAX setup, seems like pretty idiot proof. Anyway, I have one vendor quote me 1800RM to install and set up AJAX for me, another company quote me 300RM. So if all else failed, and I can't set up myself, i still have a backup to get the vendor to do it for 300RM.

Sorry my bad, just went to check the quotation, it's RM350, 50 more than i remember but should be ok la.... but this company is in Johor, Skysonic Technology.

If you are not in a rush to set up the alarm system you probably can wait a bit, my house should be ready in Jan, by then I will try to set it up myself and provide feedback / guide here. Else you can just go ahead and get a set, i feel that it should be really easy.

From Locks n more in shopee, and ATO via their website. Some item is cheaper in diff shop.
