Technical answers about CCTV and installation in Riyadh
Concise answers with a transparent calculation method. Final design depends on the site, camera count, lighting and required retention.
How many days can a 2 TB CCTV drive record?
Example: four cameras averaging 2 Mb/s each, recording continuously.
After file-system overhead and bitrate variation, a practical estimate is about 20–22 days. Higher resolution or frame rate reduces retention; motion recording may extend it. Confirm with the recorder manufacturer's calculator.
What is the difference between IP and analog CCTV?
| Point | IP | Modern analog |
|---|---|---|
| Transport | Digital over Ethernet/PoE | Coaxial cable to XVR |
| Expansion | Flexible with network design | Bound to recorder channels and cabling |
| Analytics | Broader model-dependent options | Depends on camera and recorder |
| Typical fit | New projects and expansion | Reusing existing coax |
How much does CCTV installation cost in Riyadh?
A precise price cannot be derived from camera count alone. Model, recorder, retention, cable routes, height, network, accessories and configuration all matter. Modern Monitor therefore confirms line items in a quotation and does not publish unverified prices or stock.
What camera is best for a warehouse?
The best camera matches the scene: resolution for the distance, WDR at entrances, the correct lens and field of view, suitable environmental protection, and lighting or night performance. Long-detail views may need a varifocal or corridor-specific camera.
Do CCTV cameras need internet?
Local recording can continue without internet when power, the recorder and LAN remain available. Internet is required for off-site viewing, alerts, updates or cloud recording.
Hikvision or Dahua: which is better?
Compare specific models, not brand names alone: resolution, lens, WDR, codec, analytics, recorder compatibility, local warranty and regional suffix. The right answer depends on the site's requirements.
