Review on 🔒 Enhanced Security and Convenience: Crimestopper SP-502 2-Way LCD Paging Combo Alarm, Keyless Entry & Remote Start System with Rechargeable Remote by Jacob Fish

As an electronics technician it was quite easy to install as the installation book is really helpful well explained easy to set up over the range it gives me about 1km an open range (no obstacles) with a signal line of about 300m in buildings with not very thick walls and 120m with very thick walls, I can be in the mall 3-4 floors above my car, and the signal still rotates well, not very well, the walls are much too thick the battery lasts about 3-5 weeks depending on use but charges in half an hour so you can charge and work, but in general a good alarm clock is easy to set up
