Cove is an alarm system — door sensors, motion detectors, keypad, 24/7 professional monitoring at $18-25/month. Blink is a camera system — $30-100 cameras with $3/month cloud storage, no alarm, no sensors, no dispatch. They solve different problems. Cove detects and responds to break-ins. Blink records video after the fact. Over 3 years: Cove costs $648-900 (monitoring only). Blink costs $108-360 (cameras + storage). Abode ($6/mo) gives you both — alarm system with camera support — for $415 total.

Wyze sells $20-50 cameras with $0-10/month plans and no contracts. ADT charges $29-60/month with 3-year contracts, $100-200 install fees, and $500-1,500 in equipment. Over 3 years: Wyze runs $100-500 total vs ADT at $1,544-3,660. But Wyze has no real alarm system — no entry sensors, no siren, no cellular backup on the free tier. ADT has all of that but charges 10-30x more than DIY competitors for the same Alarm.com platform. Abode ($199 kit, $6/mo monitoring, no contract) gives you ADT-level protection at Wyze-level pricing.
