Proxima zero GHz is a good choice and what are the disadvantages

Hello, I usually installed the car anti-theft protection, some hidden switch, but recently I thought to make life a little easier and less work so I found something like immobilizer ignition lock "Proxima zero GHz"
I liked the fact that it is very small (I haven't found a smaller one), it has a built-in relay and literally 4 cables to connect to it bezlogeless with a remote control that detects my presence and automatically switches on the relay.
I have a small dilemma, I was usually against mounting ready-made protections or alarms, cutting my own cable in the right place
only weaves a tow truck or pushes a toy car, that's all.
I wonder the frequency at which this immobilizer works, i.e. 2.4 GHz, they did not write on the site whether it is with a variable code or not, what can I be afraid of mounting something like this, do professionals have the opportunity to copy the signal from such protection?
I would like to make my life easier and not make it difficult, I do not want to play in topping up the hidden switch, anyway, plug it in and hide much less work.

Not every car model can be "easily" installed Proxima zero GHz.
For this blockade to be effective - you need to know its operating logic well.

The car model is audi a4 B7 1.9 tdi
I just want to know the shortcomings of this security and of course, to make it effective. With this blockade, I would eliminate the buzzer and diode that would make the thief easier and the Proxima module would be in a place where the devil says good night, of course, given the ECU replacement, the car would not light.
Maybe a colleague would tell me if this is a good choice Proxima and maybe there are other similar modules on the market to protect a car with similar dimensions?
I would not just like to hear that such Proxime thieves deactivate their toys very quickly if they are

No input [15], i.e. + 12V after turning the ignition switch.

e.g. Noxon IM 100 Immobilizer
... go to Aliexpress and enter in the search engine the phrase: '2.4 GHz car immobilizer'
and you'll know immediately what you want to mount!

I read about the Proxima and Noxon specifications and took a look at aliexpres, it seems that they do not differ after having more goodies.
Each of them is to be connected to the power supply, plus the ignition switch, but one thing annoys me that after firing the car by a person without an identifier, the system is active for several to several seconds if I read the operating instructions correctly. This discourages me very much, if I'm wrong please correct me. When calling the person selling Proxime, the person told me that without the remote control the relay is open, while the instructions state that for several seconds the system is active

You read it right.
Therefore, the "effective" installation of this lock requires experience and is not suitable for every car.

in fact, given the ECU change, the car would not light up either

The ECU for replacement has its power supply unless you cut the shaft sensor, pressure valve cr. etc .. It is also better to secure ecu against substitution

The premise of this protection was that ECU substitution is a priority.
Unfortunately, I still have a dilemma regarding the choice of a small, maintenance-free Proxima nexus protection that comes from the same bag, which after each ignition is delayed from a few to several seconds after which the protection is activated.
I found some non-branded driverless driver but there is no description for it, and I don't buy anything in the dark so I don't smile

And isn't the sense of Proxima Zero that it is really an anti-robbery? After starting the car as it does not detect the signal a bit and the car goes out and then you can not restart. At least, I read how I was interested in this security. So the thief will drive a few, dozen or several dozen meters and then stay with the car in the middle of the road. Should this mode of action be treated as a minus or a plus? Of course, assuming that we operate in legal conditions that allow it. If the car is a normal key, it should be possible to mount it, worse for a card?

Proxima and other such inventions after switching on the ignition each time without identification, the blockage will only be completed after a few seconds, for this time you can go far. Probably it is dictated by regulations or standards, it certainly does not consider it a plus. It would be best to reprogram Proxime or look for another invention

My father-in-law once wanted to move my car. He only took the keys without the ID. The car started up nicely, drove a few meters and stood in the middle of the road. I also consider this delay to work. A thief, her stays in the middle of the road with a car that doesn't want to start.
