How to Avoid Blind Spots with Your CCTV Coverage
CCTV or the closed-circuit television is proven to deter burglaries and opportunist thieves across both residential and commercial properties. Success in reducing would be thieves is however underpinned by the efficiency of the CCTV installation. Within this article, Adeva talk about how to avoid blind spots that could make your CCTV and other home security null and void. Key to full protection is a full audit and professional installation and maintenance.
Audit and Map Out Your Property
We suggest reverting initially to old school pen and paper as the initial start point. Draw the outline of the property and very simply draw in where the points of potential access are to include doors and windows, driveways and any other potential entry point onto and into your property.
The above will give you a clear view of how many CCTV placements you may need and start to map out any external features such as trees and hedges that may obscure the full range of CCTV coverage – always bear field of vision firmly in your mind.
Buy Linked CCTV Systems
CCTV is great but should ideally not be working in isolation. Look to procure CCTV systems that will link into your alarm system and trigger the alarm based on movement. This naturally needs professional calibration and in line with identifying any blind spots, should also look at any external features such as trees that, if within the field of vision, could trigger off the security systems spuriously.
Understand the Field of Vision
With all CCTV products, there should be clear documentation that highlights what is termed the field of vision. This refers to the range (distance) and angles – both horizontal (width) and vertical (height). Documentation should show how far the coverage extends and what angles are covered. Again, we would recommend a simple mapping of the horizontal coverage and by drawing the simple layout you can see what areas could potentially be covered. The vertical field of vision is a little trickier but can be determined with more ease when potential placement is determined.
CCTV are typically wall mounted or on a pole so testing the final placement can be hard for those going it alone and may involve all manner of improvised means to test the field of vision. Professional CCTV installers will have an arsenal of tools to test placement with temporary poles and fixings so in many cases going it alone can be both time consuming and futile if final placement fails to give your property full coverage.
Once you have determined where the CCTV cameras are to be placed, be sure to have a very strong final fixing. This is often one of the shortcomings of DIY CCTV installation as the fixtures are placed too loosely and can be moved either manually by a would-be burglar or by the elements – wind, rain and other weather can over time cause the CCTC camera to swivel. Once moved, the once perfect field of vision is redundant and placing CCTV away from easy reach is critical.
Light, Lighting and Seasonality
As the property owner you will hopefully have some insight as to where the sun rises and sets. This should also be a key consideration when planning placement, as blinding sunlight at any given point may obscure the CCTV view and create a coverage blind spot. The same should be applied to any artificial lighting that comes on automatically or is permanently on – hard to believe but CCTV lights are often placed near outdoor floodlights (that trigger on movement) that can obscure CCTV viewpoints. While seasonality may not be such a huge consideration in Australia, do try and consider if there are any seasonal shifts in wind and rain patterns that may block CCTV coverage.
Clean and Maintain CCTV Equipment
This should not need mentioning but is often overlooked. External CCTV equipment in particular, will over time, be exposed to the elements. Leaves, dust, water spots from rain, spider webs and other things could gather on the CCTV lens and camera so well planned periodic cleaning and maintenance is essential. Mind however that you have the secure placement discussed earlier as any movement while cleaning could displace your perfect placement leading to CCTV blind spots.
