Question 4

How much does CCTV camera installation cost in Nepal?

Accepted Answer

Contact E3 Nepal in Teku for an official site survey and customized quotation.

Question 5

What is an AI CCTV camera and how does it work?

Accepted Answer

An AI CCTV camera uses deep-learning algorithms to detect human faces, classify vehicles vs pedestrians, read license plates (ANPR), and prevent false perimeter alarms. Dahua WizMind and WizSense series cameras sold by E3 Nepal feature edge AI analytics built directly into the camera processor.

Question 6

What is the difference between IP cameras and traditional analog cameras?

Accepted Answer

IP cameras encode digital video at high resolutions (4K UHD) right at the camera level and transfer data via Ethernet or fiber cables. They support smart AI analytics (face detection, line crossing, vehicle plate recognition) and allow single-cable Power-over-Ethernet (PoE) deployment, making them standard for enterprise setups in Nepal.

Question 7

Can CCTV cameras record video without internet connection or electricity?

Accepted Answer

Yes. CCTV cameras record locally to a Network Video Recorder (NVR/XVR) hard drive without requiring internet. Internet is only required for remote mobile live viewing. During power outages, CCTV systems remain fully operational when connected to an Uninterruptible Power Supply (UPS) or solar backup power system.

Question 8

What is DJI Enterprise and where can I buy official DJI drones in Nepal?

Accepted Answer

DJI Enterprise is the commercial, industrial, and agricultural drone division of DJI. E Three Sales & Services Pvt. Ltd. (Teku, Kathmandu) is an official Authorized DJI Supplier in Nepal, providing Matrice 400 RTK, Mavic 3 Enterprise, M3T Thermal, Dock 2 autonomous stations, Agras T50 agricultural sprayers, and Zenmuse L3 LiDAR payloads with genuine warranty.

Question 9

Can drones be used for land surveying, mapping, and engineering in Nepal?

Accepted Answer

Yes! Commercial survey drones like the DJI Mavic 3 Enterprise and Matrice 350/400 RTK with Zenmuse L3 LiDAR achieve centimeter-level 3D spatial accuracy. They are widely used across Nepal for hydropower site inspection, road construction mapping, geological hazard assessment, and agricultural land surveying.

Question 10

How accurate is drone mapping compared to traditional ground surveying in Nepal?

Accepted Answer

Drone photogrammetry combined with RTK/PPK base station positioning delivers 1-3 cm horizontal accuracy and 2-5 cm vertical accuracy over large terrain areas in a fraction of the time required by traditional GPS ground survey teams.

Question 11

What is an access control system and can face recognition replace fingerprint attendance?

Accepted Answer

An access control system regulates electronic door entry using RFID cards, biometric fingerprints, or face recognition. Touchless facial recognition is fast (0.2-second authentication), prevents attendance fraud ('buddy punching'), and ensures hygienic contactless entry for offices, banks, and hospitals in Nepal.
