Comparison
CCTV vs Outdoor Beams
CCTV and outdoor beams solve different parts of the security problem for South African properties: cameras provide visual recording and identification, while outdoor beams (infrared/photoelectric) detect perimeter intrusion early and trigger the alarm. They are often complementary rather than direct substitutes.
| CCTV cameras | Outdoor beams (perimeter detection) | |
|---|---|---|
| Primary function | Visual recording and identification | Early perimeter intrusion detection |
| Deterrence | Visible cameras deter; footage for evidence | Triggers alarm before entry; less visible |
| False alarms | AI cameras reduce nuisance; still scene-dependent | Can trigger on animals/vegetation if poorly placed |
| Response value | Verification of what/who | Fast early warning at the boundary |
| Cost | Varies; per-camera + recorder | Per beam pair; generally lower per point |
| Best use case | Identification, evidence, monitoring | Perimeter early-warning, especially at night |
The verdict
This is rarely either/or: beams give early perimeter warning while CCTV provides identification and evidence, and the strongest setups combine both with an alarm and (optionally) monitoring.
