End-to-End CCTV & Biometric Access for Entebbe Office Park
Client: Commercial real estate complex
End-to-end IP CCTV and biometric access control deployment across a 4-building commercial office park in Entebbe — 120+ 4K cameras, RAID-5 NVR, biometric readers at all access points, and centralized monitoring.
Project
Design and deployment of IP-based CCTV surveillance and biometric access control across a 4-building commercial office park in Entebbe.
Client Environment
A commercial office park in Entebbe comprising 4 separate buildings with shared parking and gated entry. The park houses multiple tenant organizations with varying security requirements. Common areas include lobbies, corridors, stairwells, parking lots, and a central server room.
The Challenge
What We Walked Into
Security across the 4-building complex relied on a patchwork of legacy analog cameras, most of which were non-functional or producing unusable footage. Remote viewing was not possible — footage could only be reviewed on a local monitor in the security office. Physical access was managed through handwritten gate logbooks, providing no audit trail and no verification of identity. Unauthorized entry incidents had been reported across multiple buildings, with no video evidence available for investigation. The existing analog infrastructure could not be extended or upgraded — it had reached end of life with no replacement parts available.
Existing Environment
What Was Already In Place
Approximately 30 analog CCTV cameras of varying age and condition, connected via coaxial cable to a single DVR with 500GB storage. Many cameras had failed CCD sensors producing washed-out or black-and-white images. No remote viewing capability. Gate access controlled by manual logbooks with no electronic verification. A basic intercom system at the main gate. No structured network infrastructure dedicated to security systems.
Assessment
What We Discovered
A security audit identified that only 14 of the 30 existing cameras were operational, and of those, only 8 produced footage of sufficient quality to be useful for identification purposes. The DVR had no redundancy — a single disk failure would result in total footage loss. The analog cabling was routed alongside data and power cables in shared conduits, with several coax runs showing physical damage. The gate had no electronic access control — vehicles and pedestrians entered without verification. The server room had a standard door lock with no access logging. There was no dedicated network segment for security equipment — the few IP-capable devices shared the general office network.
Design
Architecture & Decisions
The security infrastructure was redesigned around a fully IP-based architecture with 4K cameras connected via Cat6 to a dedicated surveillance VLAN, completely isolated from tenant network traffic. A 64-channel NVR with RAID-5 storage was specified, providing redundancy against disk failure and sufficient retention for 30+ days of continuous recording. Biometric fingerprint readers were specified for building entrances, the server room, and parking gate access points, with all access events logged to a centralized platform. A centralized monitoring dashboard was designed to provide real-time camera feeds and access event logs from a single interface, accessible from the security office and remotely via encrypted VPN.
Implementation
What Was Deployed
- Installed over 120 Hikvision 4K IP cameras across all 4 buildings — including lobbies, corridors, stairwells, parking areas, and building perimeters — connected via Cat6 to dedicated surveillance switches
- Deployed a 64-channel NVR with RAID-5 configuration and sufficient storage for 30+ days of continuous 4K recording across all camera channels
- Installed biometric fingerprint readers at all building main entrances, the central server room, and parking gate access points, with each reader connected to the surveillance VLAN
- Created a dedicated, VLAN-isolated surveillance network with managed PoE switches in each building, fed by fiber backbone to the central NVR and monitoring station
- Deployed a centralized monitoring dashboard in the security office with multi-screen display, supporting real-time camera viewing, playback, and access event review
- Configured encrypted remote access for security management via VPN, enabling off-site monitoring and incident review without physical presence
Testing
Verification & Validation
- Camera coverage verification — walked all perimeters, lobbies, corridors, and parking areas confirming each camera field of view meets the specified coverage requirements with no blind spots
- Image quality verification at night and in varying lighting conditions, confirming 4K resolution provides usable identification footage at all access points and perimeter locations
- NVR recording and playback testing across all 120+ channels simultaneously, confirming continuous recording without frame drops or storage errors over a 7-day period
- RAID-5 redundancy testing by simulating a disk failure — NVR continued recording without interruption and rebuilt the array upon disk replacement
- Biometric reader testing with 200+ enrolled fingerprints, confirming authentication accuracy and access event logging to the centralized platform
- VLAN isolation testing confirming surveillance traffic is fully segregated from tenant networks, with no cross-segment communication possible
- Remote VPN access testing confirming encrypted off-site access to camera feeds and access logs with acceptable latency
The Result
Outcome
The office park now operates over 120 4K IP cameras across 4 buildings with centralized recording, monitoring, and remote access. Biometric access control is enforced at all building entrances, the server room, and parking gates, with every access event logged and auditable. The surveillance network is fully isolated from tenant traffic. Footage retention exceeds 30 days with RAID-5 redundancy protecting against disk failure. Security personnel have real-time visibility across the entire complex from a single dashboard.
