Which do I choose-Home security system

I purchased Piper system with door/lamp sensor shown last week or so and then tonight saw this Peq system. Would like Joe Harrison to explain which is/would be best …for possible future use, adding additional cameras, etc. they seemed so excited about the product…so I thought when they presented the Piper it would be perfect until I saw the new presentation tonight. Now I’m totally confused and not much time left before I need to return the first one…if I need to exchange it for the Peq one. Please Help Mr. Harrison! The Peq has night vision, allows extra cameras, monitoring,…I would truly appreciate your input and advice. Thanks so much!
