There are a couple of options that I can think of, both of which would require access to your property in Spain, so would need you to visit, or could be faciltated by a keyholder in Spain if you have one.
Securitas offer a monitored alarm system where you can have an alarm and cameras installed and then Securitas will notify you if the alarm goes off. I believe that they can also view and record what the cameras see, if the alarm is operated. They can then also either send a guard and/or call the Police on your behalf. I don't know the cost for installing the system, bu I believe it costs about €50-€60 per month for the monitoring.
Alternatively, you could self-install a doorbell, cameras, alarm, etc. using something like 'Ring' www.en-uk.ring.com which allows you to view the doorbell camera and other cameras installed inside or outside your house via an app on your phone. I know some people who use this in the UK, but I don't know if it would work from a property in Spain to the UK (I see no reason why it wouldn't, but you should check). Ring also offer monitoring services.
Hope this helps!
