Security for Northcliff homes on the ridge

Northcliff was established in 1934 on part of the old farm Waterval and named after its ridge. Northcliff Hill, also known as Aasvoëlkop, rises to about 1,807 metres, the second-highest point in Johannesburg after Observatory Ridge. The suburb's large homes are built around the steep slopes of that hill, with views to the north and south, and the Northcliff Ridge Ecopark on top.

That terrain is a big part of Northcliff's appeal. It is also why a standard security quote often doesn't fit. A flat suburban stand can be covered by a fence on the wall, a motor on the gate and a few cameras. A Northcliff property might have a driveway that climbs from the street, a house on two or three levels, terraced gardens and a back wall far below the house that nobody can see from inside. Each of those needs its own thought.

On a sloping property, the parts you can't see from the house are the parts that need covering. We walk the whole property before we suggest anything, usually from the bottom boundary up, and plan around three questions:

• What can each camera actually see? A camera mounted high on the house looks down over the terraces but can miss the foot of a retaining wall. On ridge properties, a camera at the lower boundary looking back up the garden often makes sense, with infrared or lighting so the night picture is usable. See CCTV installation.
• Where do the alarm zones start? Outdoor beams on each garden level mean the alarm can tell you where someone is, not only that something triggered. Inside the house, splitting the alarm into zones by floor lets you arm the downstairs at night while you're upstairs. See alarm systems.
• Does the fence follow the wall? Boundary walls on steep stands step up and down. An electric fence has to follow every step and corner without gaps where the wall changes height, and zoning by section shows which part of a long boundary was touched.

Link the cameras and alarm to 24-hour off-site monitoring, and someone is watching the lower garden when you can't.

On a hill like this, plenty of driveways climb or drop from the street. A gate motor on a sloping driveway needs more care than one on a flat one: the gate has to run true on its track, the motor has to suit the gate's weight, and the safety beams have to be set at the right height for a car that's on an incline.

Battery backup matters too. A heavy gate that won't open during a power cut leaves you waiting in the street or pushing it by hand. We check the battery and the charger as part of every gate job, and we look at a garage door motor if you still have to get out of the car at the top of the driveway.

Already have a motor? Tell Marco the make and send a photo of the gate and driveway. He'll tell you straight whether it's one we work on.

Some Northcliff streets have been secured with boom gates by residents. In Johannesburg, a closure or access restriction on a public road is governed by the City's Security Access Restriction (SAR) Policy of 2018. In May 2026 the City's Transport Department reminded residents that applications must be approved before any installation work starts, and that approved closures must stick to the conditions attached to them.

If your association has, or is applying for, an approved access point, we can quote the parts that are ours to do:

• Guards at the boom, working to an access procedure that fits the City's approval conditions. See estate security.
• Cameras at the access point that capture vehicles and faces clearly, day and night.
• Criminal background checks on guards and contractors who will have access to the street.

Send us the City's approval and its conditions with your enquiry, so our quote matches what the City has allowed.
