For a home security setup, 16GB RAM may be enough only if the system duties stay within the existing PC capability described.
Kingston 16GB current-gen SODIMM at R741 suits a modest home security setup that records a few camera feeds, keeps the dashboard responsive, and does not need heavy multitasking. A 16GB RAM kit can be enough for a light monitoring PC or laptop, but a busier setup with browser tabs, camera software, and local playback will feel safer on 32GB memory.
Kingston 16GB current-gen SODIMM at R741 is the practical entry upgrade when the machine is mainly used for live viewing, basic alerts, and checking clips from a small camera system. It is also the cleanest fit when the host device is a laptop-style system that uses SODIMM memory rather than a desktop kit.
TEAMGROUP VULCAN 32GB current-gen 6000 at R1,460 is the better value step-up for a desktop monitoring box. The 32GB capacity gives more headroom if the system keeps camera software open all day, stores thumbnails, and runs a browser dashboard beside recording tools.
For a small PC tucked near a fibre router cupboard, Kingston FURY 32GB current-gen 6400 at R2,300 makes sense when the system is expected to stay quick while handling more feeds, playback, and occasional exports. The 6400 speed is not the main reason to buy it for security, but the 32GB capacity helps the machine avoid feeling tight.
Kingston FURY 32GB 5600 at R5,100 is harder to justify for a simple home setup when TEAMGROUP VULCAN 32GB current-gen 6000 is R1,460. KLEVV CRAS V 32GB 7200 RGB at R6,400 is more enthusiast-focused, with 32GB capacity and 7200 speed better suited to a showpiece gaming room PC than a tucked-away monitoring machine.
Ready to choose the right memory? Use its listed spec as the filter for the 16gb upgrade enough brief, with TEAMGROUP VULCAN 32GB current-gen 6000 speed at R1,460 as the first listed match.
For home security use, decide whether the PC is handling simple monitoring or heavier continuous recording tasks.
RAM helps when monitoring software and normal desktop tasks run together, but it must suit the full security workload.
Check the memory choice against the ASUS Prime B850M-F WiFi platform before building around a 16GB target.
A security setup should be judged on steady operation first, with the RAM upgrade supporting the monitoring role it actually performs.
If the machine is only viewing feeds and running light tools, 16GB is more defensible than for heavier recording demands.
If monitoring remains unstable after memory is adequate, investigate storage behaviour, software settings and overall PC condition.

A 2700RPM pump spins its impeller 2700 times a minute to push coolant round the loop. Faster flow moves heat from the CPU block to the radiator, though a quicker pump can be a little louder. The Antec Omni Matrix 360 at R999 pairs it with an ARGB head.
Plug the three pre-connected 120mm fans into one PWM fan header, since they run from a single cable. If the lighting has its own lead, send it to the addressable header, usually labelled ARGB. Evetech's Omni Matrix 360 at R999 follows that same plan.
Targus DOCK402 combines a mobile dock with a built-in GaN charger. Its useful buying checks are host power negotiation, USB-C video support and the single-display limit, rather than assuming every USB-C laptop gets the maximum charging and resolution.
