Question 1

What is the difference between card, mobile credential, and biometric access, and how do we choose?

Accepted Answer

Card and proximity fob systems are the most common starting point, because they are cost-effective, easy to manage and familiar to most employees. Mobile credential systems use smartphones instead of physical cards, which eliminates the cost of issuing and replacing cards and works well for organizations where most staff carry phones on-site. Biometric access ( fingerprint, facial recognition or retinal scanning) is appropriate where you need higher assurance that the credential belongs to the person presenting it, such as server rooms, pharmacy areas or government facilities. The right choice depends on your security level requirements, your willingness to manage physical credentials and whether your workforce is likely to have phones available at access points. Diego Tech will make a recommendation based on the specific doors, the user population and your compliance requirements.

Question 2

What happens when an employee leaves or a credential is lost?

Accepted Answer

This is one of the core operational advantages of electronic access control over physical keys. When an employee leaves or a card is lost or stolen, that credential is deactivated in the system immediately. Most systems allow administrators to deactivate a credential from any web browser in under a minute. For organizations using mobile credentials, the access is revoked remotely and the phone effectively becomes useless for entry. Diego Tech configures administrative access so that your HR or facilities team can handle routine credential management without needing to call us for every change.

Question 3

Can access control be retrofitted onto an existing building, or is it mainly for new construction?

Accepted Answer

Retrofitting is very common and Diego Tech does it regularly in occupied commercial buildings. The primary consideration is how you route wiring from your access hardware at the door to the controller and head-end equipment, because existing buildings often require more creative wire runs or wireless readers to avoid major disruption. Door frames, strike plates and electric hardware also need to be assessed and sometimes replaced to accept the access hardware. New construction is easier because conduit can be placed before walls close, but it is not a requirement. Most commercial buildings, including older ones with hollow metal frames or wood-frame interiors, can be converted to card or mobile credential access with a thorough site assessment.

Question 4

How does access control integrate with cameras and alarm systems?

Accepted Answer

Integration means the systems communicate so that an event on one triggers a response on another. A common example is camera-to-door linking: when a specific access point is opened, the associated camera automatically records and a clip is tagged to that event, so you can pull up the footage for any door entry without searching through hours of video. When a door is forced open or held open too long, the alarm system can receive that signal and respond accordingly with a local alert, notification or dispatch depending on your monitoring setup. Diego Tech designs these integrations at the system level so the camera, access control and alarm infrastructure work together rather than operating as three separate data sources.

Question 5

How do you manage access for a business with employees working across multiple locations?

Accepted Answer

Multi-site access control is handled through a centralized management platform where all locations are administered from a single interface. An employee's credential can be granted access to specific doors at specific locations. For example, a regional manager might have access to all facilities while a warehouse worker is limited to one building and one shift window. When that employee's status changes, the update applies across all locations simultaneously. This is significantly more manageable than maintaining separate systems at each site. Diego Tech installs and configures the platform, trains your administrative users and sets up the site hierarchy so permissions are structured in a way that matches how your organization actually operates.

Question 6

What audit and compliance logging does access control provide, and how does it support regulated industries?

Accepted Answer

Every access event, whether it's a successful entry, failed attempt, door forced open or credential deactivated, is logged with a timestamp, credential ID and door location. That log is exportable and can be retained for whatever period your compliance requirements specify. In healthcare settings, this supports HIPAA requirements around access to areas where patient records or medications are stored. Government and DoD facilities use audit logs to demonstrate that only authorized personnel accessed controlled areas. Schools can document after-hours access and respond to incidents with a clear record of who was where. Diego Tech configures retention policies and reporting tools during installation so the logs are actually accessible when you need them, not buried in a system only an integrator can query.
