Your home CCTV camera system will have around two weeks of storage as standard. However I recommend customers have some additional storage capacity so at least 30 days can be recorded, even more if you wish, its not expensive.
When the storage capacity does get full, the CCTV system automatically overwrites the oldest dated recordings and will repeat doing this unless you choose to save particular recordings for perhaps evidence.
We install full HD cameras, the same level of definition as HD television pictures. So if you ever do have an incident, the footage you have recorded is more likely to be able to identify what happened and who is responsible.
When you have a suspicious caller, the definition of the security camera recordings will be as such that he/she will be easily identifiable.
