Someone was taking pictures of my home- should I be concerned?

My boyfriend was waking by our front door and noticed a car parked in the middle of the road, taking pictures of our home. When he opened the door to go ask them what they were doing, they drove off. He said the driver was an older man and there was a passenger he couldn't see from the house. He said the car was older and not very well kept, but the camera was a big, expensive looking Nikon. I'm not sure if I should be alarmed. We have owned our house for over a year now. It is a fairly small house, with little aesthetic value. We also in a small town (6,000 people) and our neighborhood is on the less nice side of the town. There are a few abandoned homes nearby. I can't think of a reason anyone would want to take pictures of our home. There should be no reason to take pictures for appraisal, and it isn't much to see (very plain, no decor, and the yard is is muddy and slushy with the weather.) I know it isn't illegal to take pictures of someone's house, but should I be concerned about this? We drove around after and did not see any similar cars taking pictures of any other homes. Thank you in advance for your answers.

Guide me to buying my first dslr or mirrorless camera?

Hi guys I'm going to buy my first dslr or mirrorless camera and I am going to be very specific on what I'm looking for so you guys can help me decide on which one to get.

What I'm going to use it for:
Landscape/City
Not really going to do videos.

Features I'm looking for
Built-in Wifi (mandatory) (or eyefi compatible)
Weatherproof(kinda optional)
Image Stabilization (optional)
Compact(I can handle weight, just don't want it to be bulky)

Cameras I've been searching up
Mirrorless:
Olympus e-m5 or e-m5 mark ii
Olympus e-m10 or e-m10 mark ii
Sony a6000

DSLR:
Pentax K50
Pentax KS2
Pentax K3-II
Canon t5i or t6i
Nikon D5300 or D5500(but this is kinda too bulky for me)

Feel free to add more that would be suited for me.

Now I know lens is just as important as the body. The kind of lens that captured my interest are the wide angle lens. Any suggestions for those are much appreciated. I think I saw a cheap one(Rokinon 12mm f2.0)

Price range:
I don't mind using second-hand so I don't think price is an issue.

Any opinion/comment is appreciated.

Thanks
John

Bring camera while snowboarding?

I'm going snowboarding and I want to bring my Nikon d5500. I've snowboard a couple times so I probably won't fall a lot but I'm still worried because I just bought the camera for my birthday. How do I reduse the risk of breaking it? I'm thinking of putting it in a small backpack but if I fall I feel like it would break because the backpack is small and thin.
