Security cameras are a long-term investment for your peace of mind, so you want a setup that lasts at least five years. Buying a quality four-pack ensures your perimeter is covered without needing to add extra cameras later, which saves you money in the long run.
Tech companies often refresh their camera lineups in the late spring, which makes fall the perfect time to find the previous year's model at a steep discount. You get the same reliable hardware without paying the premium for the newest box on the shelf.
Remember that the 0% offer is a deadline, not a gift. If you still have a balance after the 18 months are up, the bank will charge you interest on the remaining amount.
