Access control systems allow you to manage who can enter your building using keycards, fobs, or mobile credentials. These systems can track activity, restrict access to certain areas, and provide better security than traditional keys.
Video surveillance systems help deter theft, monitor activity, and provide recorded evidence when needed. Modern systems also offer remote viewing, motion alerts, and high-definition video
No. In many cases, existing DSC Power Series and Ademco Vista systems can be upgraded with cellular communication and remote access without replacing the entire system. This allows you to keep your current equipment while adding modern functionality.
Costs vary depending on the size of the system, number of devices, and level of functionality. EST Systems provides customized solutions based on your needs and budget.
Yes. With a cellular upgrade, you can arm and disarm your system remotely, receive real-time alerts, check system status, and manage users directly from your smartphone.
No. Modern systems use secure cellular communication, eliminating the need for a landline and improving reliability.
Absolutely. We regularly design solutions for multi-residential and mixed-use environments, including shared entrances, tenant-specific access permissions, visitor management, and scalable camera coverage for common areas and parking. Our goal is to provide security that supports day-to-day operations while allowing for future expansion as occupancy and needs change.
We start with a site review to understand entry points, lighting conditions, high-traffic areas, and any known security concerns. From there, we recommend camera placement, resolution, storage/retention, remote viewing options, and any supporting hardware (networking, power, mounts) to meet your operational needs and budget while maximizing usable video evidence.
Yes. EST Systems offers ongoing support and maintenance to help keep your security systems operating reliably. We can provide scheduled service, troubleshooting, and system updates as needed, and we’ll recommend monitoring options based on the type of system and your property requirements.
Yes. We offer professional monitoring services with reliable communication options, including cellular and internet-based connections.
In many cases, yes. Depending on your equipment and configuration, we can enable remote features such as arm/disarm, event notifications, user management, and live or recorded video viewing through secure mobile and web applications.
Yes. Preventive maintenance plans are available and are designed to reduce downtime and extend equipment life. Plans can include periodic inspections, testing of devices (doors, readers, sensors, cameras), firmware/software updates where applicable, and documentation of system health and recommended improvements.
Yes. We design systems with scalability in mind, so you can add doors, cameras, users, or new buildings over time without starting over. We’ll recommend equipment and licensing options that support growth and keep your system consistent across the site.
We follow security-focused configuration practices such as strong credential management, role-based user access, secure remote access options, and network segmentation recommendations when appropriate. We can also work with your IT team to ensure devices, firmware, and network settings support a secure deployment and responsible video retention/access policies.
Yes. We can schedule a site survey to evaluate entry points, existing wiring and equipment, network readiness, and operational needs. Based on what we find, we provide a clear scope of work and recommendations tailored to your property, along with an itemized proposal.
In many cases, yes. We can often integrate security systems with existing door hardware, select locking devices, network infrastructure, and certain third-party platforms depending on compatibility and your objectives. During the site review, we identify what can be reused and what should be upgraded to ensure reliability, cybersecurity, and long-term supportability.
After confirming the system design and scope, we schedule installation based on site readiness and equipment lead times. Most projects include on-site prep, device installation, wiring as needed, system programming, and verification testing. We also plan work to minimize disruption to occupants and business operations whenever possible. At closeout, we provide system walkthroughs, basic operator training, and documentation so you can confidently manage daily use.
We can set up role-based access levels, schedules, and credential policies that make onboarding and offboarding straightforward. For commercial and multi-residential properties, we can help you establish an administrative structure (property manager, office staff, or security roles) so authorized personnel can add or remove users, deactivate lost credentials, and generate access reports without disrupting other tenants or departments.
Yes. We provide responsive support for urgent security system issues, including trouble conditions, communication failures, and critical hardware problems. If you experience an alarm or access control outage, contact our service team and we’ll prioritize troubleshooting and dispatch as appropriate for your site and service arrangement.
Yes. Where appropriate, we can design an integrated solution so access events, alarms, and video are connected-such as pulling video clips by door event, associating alarms with camera views, and consolidating user management. Integration options depend on existing equipment, site requirements, and desired features, and we’ll recommend a configuration that balances usability, security, and budget.
