| Controllable versions available | Yes | Yes |
| Integration Options | Basic | Advanced |
Lifespan and Maintenance
In-ground barriers last longer and require less frequent maintenance due to their sturdy construction. Surface-mounted barriers, on the other hand, need more upkeep because of their simpler, less durable design.
Cost Breakdown
In-ground barriers come with a higher initial price tag, ranging from $7000 to $10,000 (including installation cost), but they’re more cost-effective in the long run, with annual maintenance costs of $200 to $400 and a lifespan of 10-15 years. Surface-mounted barriers are cheaper upfront, costing $2,000 to $5,000 (including installation cost), but they require more frequent maintenance and last 5 to 7 years.
Appearance
Surface-mounted barriers are more noticeable and can clash with existing architecture. In contrast, in-ground barriers are designed to blend in, with most of their structure hidden below ground.
However, there are many color options for both styles of spike strips which are suitable to just about any design layout.
Flexibility and Adjustments
Surface-mounted barriers are easier to move or modify, making them a good choice for sites with changing security needs. In-ground barriers, require excavation and careful planning for any changes, making them a better fit for long-term security setups.
Best uses for surface-mounted barriers:
