Security4U LHLCDGSM + LHPIR + LH1DS Burglar Alarm

Relatively easy to install, used a SIM card and it does what is says on the tin. The remote fob is great, there’s no need to go near the main panel after set up

Ok. A litte tricky to set up due toI nstructions. However when i got my head round them all workind fine and is great to have the remotes.

I ordered 2 different product. One with Wifi and other only GSM. Product with wifi and app is very easy install and check function. However this product little bit tricky as you have to use manual and codes to configure menu. Without manual you will not be able to change any configuration. Furthermore, while activating alarm with remote control, arm delay was not activating which makes things difficult. You have to get out from home and then arm system. Where you can not verify that it was activated or not if you not hear the sound )). One more disadvantage is delay beep could not be changed to silent mode which will attract burglars attention, where it can be broken and sim card taken out easily.

I accidentally bought two and only needed one. I installed the one into my daughters home and all is working which is great. Very easy to install the products on the doors and corners. You need to read the manual very carefully to understand coding and linking the products to the controller. It is user-friendly and not difficult to do. A great product.

The product worked well with regards to the connection with the door sensors and the PIRs. As for the connection with a mobile phone SIM, there was no way to make it work. I contacted the seller who only replied that the system works better with O2 and EE. Now, first of all such a thing would have had to write it in the product specifications before selling it, second is a completely ridiculous answer, because for example in my area both EE and O2 have little signal coverage and so I don't know how could have worked better. I have written to the seller again, but I have received no advice whatsoever. Good at selling, discreet product, bad and insignificant after-sales assistance.

I like this and it does the job very well. Very easy to fit and set up.

As with the previous review the instructions are not very clear, particularly the functional specifics. However it is pretty much plug and play. The arm and disarm function with the remotes is great and even better is the arm and disarm by SMS. The only thing I was disappointed with is that you can't isolate zones for entry/exit. So the way around this putting an alarm delay across all zones to give you time after opening the front door to disarm it manually

This is my fourth alarm I have purchased in the last two moths, the others I have had to return though two of the unites worked fine one did not. it seem the main issues with the relatively cheep alarm kits, is the sellers.Every lard I have purchased so far, all have been shipped with faulty, parts ie three bad Magnetic contacts, two with faulty PIR units I and solar siren which was also faulty. Its seem because you are not spending a lot of money the sellers have seem to have thrown quality checking before shipping. This is frustrating, as if you ask the seller to just replace the item that is not working they all seem to insist you pack the whole kit up and return it. now you have to go through the whole process again, wasting time and effort.Security4U, is my latest seller who has sent me a working unit with, two faulty parts, it is nearly a whole week now since bring this to their attention with no resolve, not even an offer to replace the faulty ones, or even to return the whole item. They have just gone silent on me. So once again I will have to disconnect all that I have put up, Good job I kept the box, then request Amazon to ask the seller to refund me. NOT IMPRESSED at all.RWalmost an expert in fitting these
