You can also call Spectrum Security and ask for a recommendation for a reliable installer

Having been in the Security business amongst others for the last 30 years the following.

Spend all your money on outside alarm detection. Indoor alarms are useless as when they detect the intruder it's already too late as they are inside your house !!!

Unfortunately outside beams are expensive but worth it .
 
So I recommend 3 to 5 outdoor detectors and maybe 3 to 5 indoor passives to cover indoors should you want to deactivate the outside beams (gardener etc).

My weapon of choice in RSA in most applications are the Optex VX Infinety wireless outdoor detectors.

Feel free to PM for any free advice  ;)

I haven’t been in this space for a while. What wireless protocol do these Optex detectors use? Still the unidirectional DSC-type? How are battery lows and wireless interference communicated?

All wireless alarms use 400 to 900 MHz for better penetration of buildings (including DSC) . Depending on the make and model you have , low battery and interference can be reported to the panel. Nearly all wireless alarms use encrypted wireless protocol today, some even using code hopping / rolling so that no one transmission is the same. (same technology used in car keys) The other subject that is rarely mentioned is the fact that the sensor communication is very brief and so very hard to intercept including varying communication frequencies ( 400 401.1 401.2 all the way up to 900 MHz).

A +1 from me, too.

One wants to know at the earliest possible point when intruders are around so as to maximise both self-preparedness and time for the cavalry to respond.

Only problem is that the wireless beams are now the targets of thieves! Do they steal the beams solely for the purpose of reselling them or to make it easier to come back the next day/night to "finish the job"?

If I recall the two frequencies allowed for security use are 433MHz and 868MHz.

My experience with DSC wireless is dismal in literally hundreds of test cases. The issue is the lack of supervision of devices which, as far as I know, is still the case.

Paradox outdoor wireless detectors have supervision.  Range is never what is specified, of course it depends on how many walls are between the tx and alarm panel

Putting the alarm panel as high as possible helps

I really like the NVR780 dual side outdoor PIR.  Very very few unwanted alarms and if set up correctly can easily cover 10m either side

Agree, Paradox is far superior, and I also enjoy the NVR780, I actually have about 15 of them in long range mode in my perimeter with no false alarms.

I was wondering if the optex/dsc wireless had progressed. Seems not. When I was more involved in that part of our business installing DSC wireless was a dismissible offence, remembering most of the work was on very large homes.

That is quite the random statement. Some Optex beams also have supervision, depending on model as with Paradox , not all Paradox detectors have supervision. Optex detectors see 12 meters and in real life up to 15. The Paradox you are bragging about does not even have Dual Technology quad circiuts (x 2 Infrared x 2 Microwave) so also not the greatest detector out their! I guess it depends how much one is willing to pay .
I have installed thousands of outdoor detectors. Risko (formely Rockonet) Israeli  and Optex (Japanese ) are the two most stable and reliable systems I have worked with, and a couple of other brands I would use before considering Paradox. The main reasons I stopped using their outdoor detectors was the South African sun would have their mounting brackets break of after a couple of years , some of their outdoor detectors are easy to bypass and the complexity of their alarm panels. As for DSC , I don't know why you associate DSC with Optex . We marry Optex with various makes of alarm panel , IDS as an example.
For interests sake both Paradox and DSC are Canadian products and I don't use them at all anymore ;)

One reason for my using Paradox products when I worked full time is because the local agent is far more forthcoming with advice and assistance.

The DSC and Optex agents are Elvey.   I was in the branch once asking, amongst other info, about battery life in an Optex HX-40, their outdoor PIR.  I heard the manager ask the accounts lady how much I had spent in the past quarter buying their products.  Whatever the answer was, he told the sales person he thought me a time waster and not to bother

When the sales person came back to the counter, I told her that if they exhibited a better attitude, I might buy more from them, and to cancel the order I had come to collect.   She blushed and started crying.   The following day I got a call from Elvey head office apologizing for a "misunderstanding".   I never went back there again.  I understand this manager was reassigned some time thereafter
