The crime landscape in Mountain Ash is predominantly shaped by social and economic factors common to many Welsh valleys. The area has historically experienced challenges relating to employment and opportunities, which can contribute to issues such as anti-social behaviour and petty crime. The close-knit community structure also means that incidents, even minor ones, can be widely felt and discussed. The presence of local businesses and a relatively dense population also presents opportunities for certain types of crime, like shoplifting, although these are often linked to broader issues of deprivation and opportunistic theft. Understanding these underlying factors is key to addressing the root causes of crime within Mountain Ash.

Crime rates in Mountain Ash have demonstrated a degree of stability between January 2025 and December 2025. While monthly fluctuations occurred, with peaks in March and July (reaching 8.8 and 9.4 per 1,000 respectively), the figures generally remained within a narrow range. The lowest monthly rate was observed in December (6.5 per 1,000).

Traditional CCTV systems often only record footage after a crime has occurred. While useful for investigations, they don't prevent incidents. scOS offers a proactive approach. Imagine a burglar approaching your property – traditional systems record them; scOS detects them at the boundary using AI-powered multi-camera intelligence, instantly activating lights and speakers to deter them. The DVLA vehicle verification feature can identify cloned or stolen vehicles, and the system learns your routines to distinguish genuine activity from threats. This visible deterrent and immediate response significantly reduce the likelihood of a successful crime. Reading crime statistics is one thing; actively protecting your property is another. scOS provides that level of protection.
