Technical guides written for security installers, integrators and low-voltage contractors.

• Warehouse Surveillance Blueprint: Camera Layout, PoE & 30-Day Storage — A practical warehouse security camera planning example: separate aisle detail from wide-area coverage, build a camera schedule, and calculate power, bandwidth and recording storage before quoting.
• Turret vs. Dome IP Cameras: Vandalism Resistance, Glare, & Night Vision — When to spec a turret and when to spec a vandal dome: how they differ on IR glare, impact resistance, upkeep, and aiming, with a quick chart for picking one.
• NVR Storage and Bandwidth Sizing Guide for Commercial Camera Systems — How to calculate terabytes for a 30-day retention requirement, estimate camera bitrate by resolution and codec, and size recorder and network throughput before the job ships.
• NDAA Compliance Guide for Security Contractors and Integrators — What Section 889 of the NDAA actually bans, how it reaches private integrators through federal contracts, and how to document compliance so a camera package survives a bid review.
• LPR Camera Sizing Guide: Getting Readable Plates Day and Night — Pixels per foot, shutter speed, mounting angle, and lighting — the four numbers that decide whether a license plate recognition camera actually reads plates, and how to get them right before the truck rolls.
• PoE Switch Buying Guide for IP Camera Installations — How security integrators should size PoE switches for IP camera systems — power budgets, PoE standards, uplinks, VLANs, and the mistakes that cause site call-backs.
• How to Build a Complete Talk-Down Surveillance System — The system and operations blueprint for talk-down surveillance: architecture, analytics triggers, escalation workflow, operator scripts, and relay integration.
• Why a Custom-Built Wisenet WAVE Server with NorthStar Cameras Outperforms Off-the-Shelf NVRs — A purpose-built Wisenet WAVE server paired with NorthStar IP cameras delivers higher channel density, longer retention, and better forensic search than any off-the-shelf NVR. Here is why integrators are making the switch.
• IP Horn Speakers for Talk-Down: Coverage, SIP Setup and Wiring Guide — A hardware and setup guide for IP horn speakers in talk-down security: coverage math, 15W vs 30W selection, SIP vs VMS audio paths, and an installer checklist.
