Most CCTV problems don’t show up until someone needs the footage. The front camera caught a figure at 2am, but the side gate they came through never made it into frame. That gap is a blind spot, and most properties have at least one.
When you’re comparing the security cameras Perth installers offer, the camera count matters less than where each one points. Blind spots come from walls, fences, trees, poor lighting and cameras mounted too high or too far away. Here’s how to find them and close them before they cost you.
Walk the Property Before Choosing Cameras
Start outside, not with a product brochure. Walk the boundary and note every way in: front door, garage, side gates, back door and any shed or granny flat. Businesses should add loading bays, staff doors, stockrooms and car parks.
For each spot, decide what the camera needs to capture. A doorway camera should show a face, while a yard camera only needs to show movement across the space. Writing this down stops you buying six cameras that all watch the driveway.
Get the Angle and Height Right
A high-resolution camera in the wrong spot records less useful footage than a modest one placed well. Mount it too high and you get the top of a cap instead of a face; too low and someone can knock it out of position. Around 2.5 to 3 metres suits most homes.
Lens choice matters too. A wide 2.8mm lens covers a driveway but shrinks distant people to a few pixels, while a narrower lens gives detail at a gate or doorway.
Cover Corners With Complementary Views
Walls, pillars and building corners create the most common blind spots. A camera on the front of a house usually can’t see along the side path, so a second camera on the side wall, looking back towards the front, closes the gap. At key entrances, a little overlap helps: one camera gives the wide view while another captures faces at the door.
That’s why it pays to judge the CCTV camera systems Perth suppliers sell by how the cameras work together, not just the number in the box. Four well-placed cameras often beat six installed at random. For large yards and car parks, a 180-degree panoramic camera can replace two or three fixed ones, though detail drops towards the edges.
Fix the Blind Spots Light Creates
A spot can be in frame and still be a blind spot if it’s too dark, or too bright, to read. Unlit side paths, deep shadow under carports and a west-facing camera staring into the afternoon sun all leave gaps.
Infrared night vision handles darkness in black and white, colour night-vision cameras keep detail in low light, and wide dynamic range (WDR) balances bright and dark areas in the same shot. Check footage at dusk and after dark, not just at midday.
Use Smart Detection, But Don’t Lean on It
AI detection can tell people from vehicles and alert you when someone crosses a virtual tripwire at a gate or enters a yard after hours. It’s useful at boundaries and entrances. What it can’t do is see through a shipping container or a parked ute: detection only works on what the lens can see, so placement still comes first.
Re-Check Coverage After Changes
Blind spots creep back. A new fence, a growing hedge, a stack of pallets or a car parked in a new spot can quietly block a view that was clear on installation day. Every few months, scroll through each camera’s live view and some night footage, and confirm every entrance is still visible and recording.
How VP Security Solutions Plans Coverage
VP Security Solutions builds CCTV security systems Perth homes and businesses can rely on, starting with a free, no-obligation site check. A technician assesses camera locations, coverage areas and cabling before you receive a fixed quote.
Its Dahua packages use 6MP AI cameras with smart detection, and the TiOC PRO kit adds a built-in light and siren for active deterrence. For bigger sites, the team designs around the coverage needed rather than a set package, including a recent 16-camera warehouse and a 24-camera grocery store installation in Perth.
Frequently Asked Questions
How much does it cost to install security cameras in Perth?
At VP Security Solutions, a four-camera Dahua system costs $1,499 fully installed, a TiOC PRO four-camera kit $2,049 and a six-camera kit $2,449 (October 2026 prices). Each includes the recorder and hard drive for a standard single-storey home; larger or commercial jobs are quoted after a site check.
What are the best security cameras in Perth, Australia?
Wired IP cameras from professional brands such as Dahua, Hikvision, HiLook and Uniview suit Perth properties best, recording locally to an NVR. To cut blind spots, prioritise strong night vision, WDR for harsh sun and the right lens for each position over raw megapixels.
What’s the best security camera for the money?
A wired 4MP to 6MP turret camera with AI person detection, recording to an NVR with no subscription, is the best value for most homes. VP Security’s $1,499 four-camera kit works out to under $375 per camera, recorder and installation included.
What security system do burglars hate?
Burglars tend to avoid visible, layered security: an alarm, outdoor cameras, motion lighting and solid locks. In a University of North Carolina at Charlotte study of 422 convicted burglars, about 60% said they would look for another target if they found an alarm. No setup is burglar-proof, but layers make yours the harder target.
How high should security cameras be mounted?
Mount most outdoor security cameras 2.5 to 3 metres high. That keeps them out of easy reach while still capturing faces rather than the tops of heads. Doorway cameras can sit slightly lower; cameras covering wide yards can go higher.
How many security cameras do I need for my house?
Many Perth houses are well covered by four cameras: front door, driveway or garage, side access and backyard. Corner blocks, larger lots and homes with sheds or granny flats often need six or more. A site check confirms the right number for your layout.
Final Thoughts
Blind spots are rarely about the cameras themselves. They come from placement, lighting and changes around the property. Plan coverage entrance by entrance, test it at night and re-check it every few months. To have your property assessed, book a free site check with VP Security Solutions.
