This is not a standard security camera; it is an industrial-grade surveillance unit with on-board AI capabilities. It features 25x optical zoom, infrared night vision up to 200 meters, and AI-powered auto-tracking of vehicles or pedestrians. The AI can detect traffic anomalies, such as accidents or stopped vehicles, and automatically alert the central command center. The unit is housed in an IP67-rated weatherproof dome, ensuring reliable operation in all conditions. The market price for such a camera is approximately $1,200 - $1,800 [7].

4.2. Environmental Sensor Suite

To provide valuable data for smart city management, a comprehensive environmental sensor suite is included. This module measures key atmospheric parameters in real-time:

• Air Quality: PM2.5 and PM10 particulate matter, CO2, NOx.
• Meteorological Data: Ambient temperature, humidity, and barometric pressure.
• Acoustic Data: Noise levels in decibels (dB). This data, transmitted via LoRaWAN or 4G, enables authorities to monitor pollution hotspots and manage environmental compliance. A professional suite with these capabilities costs between $1,000 and $1,500 per unit [8].

4.3. LED Information Display

Communication with drivers is enhanced via a high-brightness, full-color P5mm LED display. This IP65-rated outdoor screen is used to broadcast real-time traffic alerts, weather warnings, travel time information, or public safety announcements. Its 5000+ nit brightness ensures readability even in direct sunlight. The estimated cost for a pole-mounted display of this type is $3,000 - $4,000 [9].

4.4. WiFi 5G Connectivity

As a connectivity node, the pole is equipped with a WiFi 6 (802.11ax) outdoor access point, providing high-speed internet access for travelers and serving as a communication backbone for other IoT devices. The system is also 5G-ready, with the option to integrate a 5G small cell to densify cellular network coverage along highways, a critical step for enabling autonomous vehicle communication (V2X). The WiFi 6 AP costs approximately $400 - $500 [10].

4.5. Public Address (PA) System

For emergency broadcasts, a weatherproof IP66-rated PA system with a horn speaker is integrated. This allows the traffic management center to issue clear, audible instructions to drivers during emergencies, accidents, or evacuations. The system can be activated remotely and is a vital tool for public safety.

4.6. Electric Vehicle (EV) Charger

Supporting the global shift to sustainable transportation, the pole base incorporates a 7kW Level 2 AC EV charger. It features a universal Type 2 connector and is compliant with the Open Charge Point Protocol (OCPP), allowing for integration into any public charging network. This provides a convenient charging point for electric vehicles, generating a potential revenue stream and encouraging EV adoption. A smart commercial charger of this class costs between $2,000 and $3,000 [11].

5. ROI and Economic Viability: A Data-Driven Case

The initial investment in the 12m Highway 7-in-1 Premium, priced between $28,000 and $38,000, is justified by substantial long-term returns.

Example ROI Calculation (per pole):

1. Energy Savings: A 200W LED light replaces a 450W HPS lamp (including ballast draw). Operating 12 hours/day (4,380 hours/year) at an electricity rate of $0.15/kWh:
   • HPS Annual Cost: 0.45 kW * 4,380 h * $0.15/kWh = $295.65
   • LED Annual Cost: 0.20 kW * 4,380 h * $0.15/kWh = $131.40
   • Annual Energy Savings: $164.25 (A 55.6% reduction)
2. Maintenance Savings: HPS lamps require replacement every 3-4 years at a cost of ~$300 (lamp + labor). The LED luminaire's 12+ year lifespan eliminates at least three replacement cycles, saving approximately $900 over its lifetime, or $75 per year.
3. Revenue Generation (EV Charger): Assuming 2 hours of use per day at a net profit of $1.50/hour, the EV charger can generate: 2 h/day * 365 days * $1.50/h = $1,095 per year.

Total Annual Value: $164.25 (Energy) + $75 (Maintenance) + $1,095 (EV Charging) = $1,334.25 per pole.

This calculation does not even include the immense societal value derived from improved traffic flow, faster emergency response, public WiFi access, and valuable environmental data. The consolidation of seven functions into one installation dramatically reduces capital expenditure compared to deploying seven separate systems, saving an estimated 40-50% in installation and civil works costs.
