Quick take: ADT and Blink target different buyers. One is stronger on structured monitoring, the other on camera-first DIY flexibility. Run full 36-month math before locking into a plan.
At-a-glance verdict
- Pick ADT if you prioritize formal monitoring workflows and predictable escalation handling.
- Pick Blink if you want lower-friction DIY setup and flexible camera expansion.
- Best-value move: compare both with no-contract alternatives before checkout.
What to model over 36 months
- Monitoring and cloud subscription totals.
- Equipment bundle pricing and add-on device expansion.
- Contract obligations, cancellation terms, and early-exit costs.
- Notification reliability, live-view latency, and app stability.
Where each option tends to win
ADT strengths
- Works for households that prefer structured monitoring and guided support.
- Can fit buyers who want a more traditional alarm-service model.
Blink strengths
- Flexible camera-first rollout with lower setup friction.
- Good fit for households that want DIY control and lighter commitment.
Bottom line
Choose based on your risk tolerance for long-term lock-in versus flexibility. The cheaper-looking option upfront is not always cheaper over three years.
