Why not call a friend and ask them to check in on your place to see if it is secure.

When you get home buy an IPcam and install it where you can see your rig, so that you can log onto it from your phone to look in your place to see if all is ok for when you are away next. You can set them up to record and have motion detection also.

Buy and install a motion detection alarm that calls you from a cheap mobile phone if anyone enters your home while you are away.

Order yourself a pizza for delivery and wait to see if they call back to say no answer, whats going on ? If after an hour there is no call you should call the pizza place back and say where is my pizza. If they say it was delivered and paid for then some one is in your home eating a pizza probably.

You can do the same with a taxi / cab,

Call your landlord to say you had a call saying you had been broken in to, you have called the police could he go and wait for them to arrive .

May be your rig is just malfunctioning, or the place is on fire because it overheated and the building is burning down.

I would not worry too much if you had been broken in to I am sure you would of had a call by now, and the insurance will pay for you a brand new rig in that event or if there has been a fire.
