A good smart floodlight keeps an eye on your driveway and should last about five to seven years. Don't cheap out on off-brand sensors that lag or trigger every time a moth flies by. Look for last year's model from major brands when the new line drops in late summer. The hardware is basically the same, but the price drops fast.
If you are already doing exterior maintenance like painting or gutter cleaning, this is the perfect time to mount the camera. Instead of paying $250 upfront, you can spread the cost. The Citi Simplicity® Credit Card gives you 0% for 18 months on purchases and balance transfers from date of account opening. That brings your monthly cost down to $13.89.
Keep in mind that 18 months goes by fast. The intro window is a strict deadline, not free money. If you have any balance left when the promotional period ends, you will start paying regular interest on the remainder. Set up auto-pay for the monthly amount to stay safe.
