Why Wire‑Free 4G SIM & Solar CCTV Is Mandatory for Remote Sites
Rajasthan’s arid zones, scattered farms and sprawling construction yards lack reliable power and broadband. A 4G SIM‑enabled camera paired with a solar panel delivers continuous surveillance without trenching cables or leasing fiber. KAS Info Tech, ISO 9001:2015 certified and a trusted partner for Rajasthan Police (850+ stations) and Indian Railways, has rolled out over 1,200 such installations across Alwar, Jaipur and the NCR industrial corridor.
Zero‑Wiring Installation Blueprint
- Mounting pole: Galvanised steel, 2.5 m height, pre‑drilled for solar panel, 4G antenna and PIR sensor.
- Camera: 4G Solar PTZ (4‑MP, 30 × optical zoom) with built‑in SIM slot.
- Power: 100 W monocrystalline panel + MPPT controller.
- Connectivity: 4G LTE Cat‑4 modem integrated in the camera chassis.
- Grounding: Earth rod 2 m deep, copper‑clad for lightning protection.
All components are bolted, no trenching, no AC mains required. The entire kit fits in a single 30 kg crate, enabling a two‑person crew to finish installation within 2 hours.
Battery Backup Sizing for Cloudy Winter Days
Rajasthan’s winter can deliver <10 h of overcast conditions. To guarantee 24 h operation, calculate the required lithium‑ion capacity using:
Required Ah = (Camera Power W × 24 h) / Battery Voltage Example: 12 W camera × 24 h = 288 Wh Battery voltage = 12 V → Required Ah = 288 Wh / 12 V = 24 Ah Add 30 % safety margin → 31 Ah ≈ 1 × 40 Ah battery (single unit)
KAS Info Tech recommends a 48 V, 40 Ah Li‑FePO₄ pack (₹9,800) for a single camera, or a shared 48 V, 120 Ah pack (₹28,500) for up to three cameras on the same pole.
SIM Data Consumption & 4G Plans
Each 4 MP camera streams at 1.5 Mbps (H.265). Daily data per camera:
1.5 Mbps × 86 400 s = 129 600 Mb ≈ 16 GB per day
For motion‑triggered recording (PIR enabled) with 80 % idle time, average drops to ~3 GB/day. Recommended plans:
| Provider | Plan | Cost/Month | Data |
|---|---|---|---|
| Jio | ₹199 | ₹199 | 30 GB |
| Airtel | ₹249 | ₹249 | 40 GB |
Choose a plan with at least 30 GB/month per camera, or consolidate multiple cameras on a single SIM using a multi‑camera NVR that multiplexes streams.
PIR Motion Sensors – Power Saver & False‑Alarm Reducer
- Passive Infrared (PIR) module draws <0.5 mA at 5 V (≈2.5 mW).
- Configured to trigger recording only when motion is detected for >5 seconds.
- Reduces average data by 70 % and extends battery life by 40 %.
- KAS Info Tech integrates PIR directly into the camera housing, eliminating separate wiring.

All prices are as of Oct 2026 and include GST. KAS Info Tech offers a 10 % discount for bulk orders (≥5 poles) and a 24/7 helpline (+91 80581 22233) for post‑install support.
Implementation Checklist
- Site survey – confirm sun‑hours, pole locations and line‑of‑sight for 4G.
- Select camera model (2‑MP for low‑budget, 4‑MP for critical assets).
- Calculate battery Ah using the formula above; add 30 % safety.
- Order solar panel (≥100 W) and MPPT controller matched to battery voltage.
- Provision 4G SIM with at least 30 GB/month data.
- Mount pole, attach panel, battery, camera and PIR module.
- Configure camera: set motion‑triggered recording, data compression (H.265), and cloud storage schedule.
- Test live feed via KAS mobile app; verify backup runtime by simulating night mode.
- Document serial numbers, SIM ICCID and warranty details.
- Schedule quarterly performance audit – battery health, panel output, data usage.
Expert Advice: For farms larger than 5 ha, cluster three cameras on a single 48 V, 120 Ah battery bank. This reduces per‑camera cost by 18 % and simplifies maintenance.
Scalability & Integration with Existing Infrastructure
KAS Info Tech’s NVR software supports hybrid fleets – mixing 4G solar units with legacy analog cameras already deployed at DMart warehouses. The platform provides a unified dashboard, role‑based access and AI‑driven analytics (human detection, loitering alerts). Integration with existing ERP systems is achieved via REST APIs, enabling automated incident tickets.
Conclusion
Wire‑free 4G SIM and solar CCTV eliminates the high CAPEX of trenching and grid extension, delivering reliable surveillance for remote farmhouses and construction sites across Rajasthan. By sizing lithium‑ion batteries correctly, selecting appropriate 4G data plans, and leveraging PIR motion sensors, operators achieve up to 40 % longer battery life and 70 % data savings. KAS Info Tech’s proven track record, ISO‑certified processes and 24/7 support ensure a hassle‑free deployment from survey to handover.
