Physical SecurityIP CCTV Surveillance
H.265 IP cameras with NVR/VMS, designed around what each must see: faces, plates or overview. Built for dust, rain and power dips.
What we usually find on site
Something happens, you pull up the footage, and the camera saw a person but not a face. Or it's black at night. Or it only keeps three days and the incident was last week. We see this constantly in systems installed without a design.
We start every camera with one question: what does this camera need to see? IEC 62676-4 sets the pixel density (pixels per metre at the target) for each level:
| Level | Pixels per metre | Lets you |
|---|---|---|
| Detect | 25 | Tell a person or vehicle is there |
| Observe | 63 | See actions and clothing |
| Recognize | 125 | Recognise someone you know |
| Identify | 250 | Identify a stranger |
Only then do we choose resolution (4MP–4K), lens (fixed or varifocal) and form factor (dome, bullet, PTZ, fisheye). A wide-angle 4MP camera covering a whole car park gives a fine overview and will never show a face. It's the most common mistake we see.
Day and night
Backlit entrances need true WDR, not digital WDR. At night we use low-light colour cameras or IR matched to the distance. Outdoor cameras are IP66/IP67 and IK10 vandal-resistant, with surge protection. In the rainy season, insects swarming the built-in IR can trigger motion alerts all night; a separate IR illuminator helps.
Recording and management
H.265 needs roughly half the storage of H.264 at similar quality. We size disks from the number of days you need and use RAID for important systems. Cameras sit on their own VLAN, default passwords are changed, and NVR ports are never opened to the internet. Mobile viewing goes through a VPN or a securely configured vendor cloud. ONVIF lets cameras and recorders from different brands work together at a basic level. And a UPS is a must: burglars know when the power's off.
What it does
Designed around the task
Detect, observe, recognise or identify, by pixels per metre.
H.265 storage savings
More days of footage on the same disks.
Built for outdoors
IP66/IP67, IK10 and surge protection.
Night performance
WDR, low-light and IR matched to distance.
Safe mobile viewing
Via VPN or properly set-up cloud, no open ports.
PoE and UPS
One cable for power and data; recording continues in outages.
Cyber-hardened
Own VLAN, strong passwords, firmware kept current.

FAQ
What resolution do I need?
It depends what you need to see and how wide the scene is. Identifying a person needs about 250 pixels per metre, so a 4MP camera (2560 pixels across) covers at most about 10 metres of width at that level.
How many days of recording will I get?
It depends on camera count, resolution, frame rate, compression and disk size. Tell us how many cameras and how many days you need and we'll work it out, or try our CCTV storage calculator.
Can I mix camera and NVR brands?
Yes, through ONVIF for basic viewing and recording. AI features and advanced search usually only work fully within one brand.
Why IP rather than analog?
Higher resolution, one cable with PoE, easy expansion and on-camera AI. But if the building already has coax and the budget is tight, analog HD is still a sensible choice.
