Installing a CCTV security system is one of the best ways to protect your home, office, shop, or warehouse. However, many people are confused about whether they should choose a DVR (Digital Video Recorder) or an NVR (Network Video Recorder) system.
Both systems record surveillance footage, but they work differently and are suitable for different environments.
At Lasani Hi Tech, we provide complete CCTV installation, maintenance, and repair services, helping customers choose the right surveillance solution for their needs.
What is a DVR System?
A DVR system works with analog CCTV cameras.
The cameras send video signals through coaxial cables to the DVR, where the footage is processed and stored.
Advantages of DVR Systems
- Lower installation cost
- Reliable performance
- Suitable for small businesses
- Easy maintenance
- Compatible with existing analog cameras
What is an NVR System?
An NVR system works with IP (Internet Protocol) cameras.
Each camera processes the video itself and sends digital footage through a network cable (Cat6/Cat5e) to the NVR.
Advantages of NVR Systems
- Higher image quality
- Easy remote access
- Better scalability
- Smart AI features
- Simple network integration
