“Will currently installed SimpliSafe sensors, etc. work with this new base unit, or will they all need to be replaced? Thank you.”

• The two systems are completely incompatible, Nothing on the old works on the new, nothing on the new works with the old. (I saw in a forum that the camera MAY work with both. Check before buying.) Best Buy is currently selling both the old and the new systems. I believe the old are SS2 (second generation) and the new are SS3. In addition you can tell the two apart because all the new components are smaller than their earlier counterparts. If you care which you get, check carefully before you buy. I think it is unconscionable for Best Buy to sell both systems side-by-side without a very clear indication that one is the newer model, incompatible with the old. (If the difference is indicated in the descriptions, I missed it.) The fact that they are different systems should be clearly stated and obvious to the consumer.

• I believe they need to be replaced with the new sensors. I saw that someone asked this very question on Facebook and simpisafe responded that the new unit only works with the new sensors.
