Security Industry Regulation Agency (SIRA) provides recommendations on how to effectively maintain CCTV systems in extreme heat conditions.
With the increase of temperatures during summer, maintenance of CCTV systems becomes vital to ensure continuity of its function efficiently.
Cameras and devices get exposed to harsh weather conditions that may impact their performance if no correct measures are taken.
Below is a guide to maintaining CCTV systems in extreme heat, according to recommendations from SIRA.
Protection of external cables
Selection of proper cables
Weather-resistant cables – it is necessary to use cables specifically designed to withstand extreme heat.
Protection of cables from weather
Metal pipes or channels – to protect cables from direct exposure to sun rays and humidity, you may use metal pipes or channels. Such protection shall prevent damage that may lead to poor CCTV system performance.
Inspection and maintenance
Regular check – you may inspect cables regularly to detect any signs of damage or fractures.
Replacement of damaged cables – in case of any damage, use damaged cables immediately to avoid any difficulties with the CCTV system.
Selection and maintenance of cameras
Selection of the right camera
IP66 classification or higher – ensure that selected cameras are within IP66 classification or higher, which means they are water-and-dust-resistant.
They must also be designed to maintain extreme temperatures to ensure good performance.
Inspection and maintenance
Cleaning lenses – keep your lenses clean regularly to prevent accumulation of dust and dirt, which will contribute to the enhancement of image quality.
Regular maintenance
Inspect your cameras regularly to ensure they are working correctly and to detect any possible malfunctions.
Protection of NVR
Selecting the right location
Cool and well-ventilated place – place an NVR device in a cool and well-ventilated place, away from direct sunrays. Use shelves with good ventilation that may help in maintaining device temperature.
Clean ventilation gaps regularly to avoid dust build-ups which may lead to high device temperatures.
High temperature management
Cooling fans – you may use small fans of cooling devices to maintain a proper temperature of NVR.
Preventing power shortage
UPS usage – to ensure the continuation of CCTV system operation in case of power shortage, use UPS (Uninterruptible Power Supply) devices.
Such devices provide back-up power and contribute towards protection of registered data.
General maintenance
Regular maintenance
Scheduling maintenance – organise periodical maintenance of security systems each three months, especially during summer, to ensure there are to issues and to maintain the efficiency of the CCTV system.
Inspecting power connections
Safe connections – ensure that electricity/cable connections are properly and safely connected to avoid any issues that may affect CCTV system performance.
Conducting periodical tests
CCTV system test – regularly test the CCTV systems to ensure it is working properly and that all devices are connected and efficiently working.
Conclusion
By following such advice, you can ensure continuity of your CCTV system and the highest level of performance.
Regularly maintain devices to avoid issues and to ensure effective protection.
