Reliable wireless access with excellent range and performance, future-proofed for growing device demands.


Surveillance System

Cameras Installed:

  • 3× G5 Bullet
  • 1× G4 Bullet
  • 5× G6 Bullet

Coverage Strategy:
Camera placement was designed to provide comprehensive exterior and entry-point monitoring, with high-resolution video and night vision across all key areas.

Result:
Clear, dependable video surveillance with remote access and intelligent motion alerts—boosting both security and peace of mind.


Access Control

Streamlined access control that’s easy to manage and integrates directly with the building’s broader network infrastructure.


Cabling & Backbone

Case Study

Gillette Church of Christ AV Overhaul: Projection, Audio & NDI Integration

Project Overview

To improve visual clarity and audio capture in the worship space, we replaced aging projection and audio systems with modern, network-connected solutions tailored for both in-room experience and livestreaming.

Visual Upgrade

  • Old System: A 12-year-old bulb-based projector with dim, uneven output.
  • New Installation: A bright, energy-efficient laser projector, delivering significantly improved clarity, contrast, and long-term reliability.
  • Result: Crisp, vivid visuals that remain clear even in ambient lighting—ideal for worship lyrics, video content, and scripture slides.

NDI Video Distribution

  • Device Installed: BirdDog Play connected to the projector.
  • Functionality: Allows any NDI video signal on the network to be sent directly to the projector.
  • Use Case: Easily display live video, pre-recorded content, slides, or even camera feeds—wirelessly and with low latency.
  • Result: Flexible content distribution with no need for physical HDMI rerouting or manual input switching.

Audio Capture Enhancement

  • Installation: Two ceiling-mounted drop microphones positioned to capture congregational singing and ambient room sound.
  • Purpose: Designed to enrich livestream audio and recordings by including the full worship environment, not just the pastor’s mic.
  • Result: Natural, immersive audio that brings the online audience closer to the in-person experience.

Outcome

This AV upgrade not only modernized outdated equipment but also created a future-ready foundation. With network-based video distribution and improved audio capture, the church now has the tools to elevate both in-person worship and online engagement.
