Security cameras are fast becoming the must have item if you value your home and personal security. Their visible presence alone is a fantastic deterrent by presenting a simply ‘too hard’ target for would-be thieves. Here are some considerations to Building a Better Home Surveillance System.
When considering a home Surveillance system its generally a good idea to get back to basics, and by that, we mean the property as a whole should be assessed for the best possible outcome.
Practically, there is no 100% guaranteed security solution- if someone wants in to your property bad enough, it will generally happen, but by making your property the most unappealing target, we can drastically reduce and even stop this happening in the first place.
To start, first assess your property and its surrounds are fences, gates and common access areas secure? Can they be secured? If you’ve answered no, these area’s are your points of egress and should be a priority for your CCTV camera’s and possible further reinforcement. Higher fences, sturdier gates and less cluttered spaces are what we’re after.
Moving from the surrounds and to the home itself, it’s now time to check all locks on your doors, windows, skylights and garage. Make sure they’re key lockable and functional. Not only do most insurance companies require this, they may possibly offer better premiums. Make note of all external doors and windows as these are normally the most common points of ingress a would-be criminal will enter.
Now we move into the premises as its time for a stocktake. Make note of all valuable items and electronic equipment. Note down serial numbers and take some high-resolution photos and upload to a cloud service provider like Dropbox for safe cleaning. While not explicitly security related, having these items on file can make recovery easier is they end up at your local Pawn shop and provide evidence to your insurer and assist with your claim. Also be sure to mark these valuables with your drivers licence number in an inconspicuous spot, this too will aid in their recovery.
Now we can plan our CCTV system with confidence. Start with a rough diagram of your block and floor plan. Here you should aim to have complete coverage with some slight overlap of your points of ingress. While it can be tricky and costly to get a complete, effective 360-degree view, taking the time to get it right reaps benefits should an incident occur. Make note of your the FOV required. Cameras come in many configurations, so make sure the FOV (and range) are up to the task. Here’s a rough guide of what to expect.
- 2.8mm = 90° horizontal field of view
- 4mm = 60° horizontal field of view
- 12mm = 25° horizontal field of view
Make sure your chosen cameras suit your intended purpose. Do you require excellent night viewing resolution? Is the camera facing direct sunlight? Is there adequate mounting space? This questions will need to be addressed prior to purchase as there is a camera to suit almost any application.
