Where is the best place to put CCTV cameras on a house?

The four most important locations are the front door (positioned to capture clear eye-level faces of visitors), the driveway (facing outward to capture vehicle registration plates), the rear patio or garden bifold doors (the most common forced entry point), and secluded side passages or alleyways.

What is the best height to mount outdoor CCTV cameras?

The ideal mounting height for domestic CCTV is 2.8 to 3.2 metres (around 9 to 10 feet). This keeps the camera out of reach of casual vandalism while maintaining a shallow viewing angle (under 30 degrees) necessary to identify facial features under UK police DORI standards.

Why shouldn't cameras be mounted too high under second-floor roof apexes?

Mounting higher than 3.5 metres produces 'head-top syndrome', where the camera looks almost straight down, capturing only hoods, caps, and the tops of heads rather than recognisable facial features. High cameras also suffer from increased spiderweb build-up and poor infrared illumination at ground level.

How much hard drive storage do 4 4K CCTV cameras need for 30 days?

Four 4K (8MP) cameras recording continuously at 15 frames per second using efficient H.265 compression at 6 Mbps generate approximately 64.8 GB per camera per day (259 GB total daily). For 30 days of retention, you need 7.78 TB of raw capacity, requiring an 8TB or 10TB surveillance hard drive.

Can outdoor cameras be mounted directly to UPVC fascia or soffits?

Yes, provided they are securely anchored into solid timber battens behind the plastic hollow soffit, or mounted using deep IP66 conduit junction bases. Hollow plastic alone flexes in high winds, causing motion-sensor false alarms and image vibration.

Are Wi-Fi security cameras as reliable as wired PoE systems?

No. Wi-Fi cameras rely on the congested 2.4GHz wireless spectrum, which is susceptible to dropouts through thick UK cavity walls and vulnerable to inexpensive handheld RF deauthentication jammers. Commercial-grade systems use hardwired Cat6 PoE (Power over Ethernet) for 100% uninterrupted 24/7 recording.

Do I need planning permission for home CCTV in the UK?

In almost all UK residential properties, home CCTV is permitted development and does not require planning permission. Exceptions apply if the building is Grade I or Grade II listed, or in certain conservation areas with strict alterations limits.

What are the UK privacy rules for domestic CCTV pointing near a neighbour?

Under UK data protection law and ICO guidance, domestic CCTV that captures images beyond your property boundary (such as neighbouring gardens or public pavements) is subject to GDPR rules. Professional installers configure digital privacy masking to blackout neighbouring windows while keeping perimeter boundaries fully protected.

2. Choose your camera preferences

Preferred Mounting Style

Visible Deterrence Prominent corner turrets that signal property is alarmed

Discreet Under Eaves Tucked cleanly into white or anthracite roof soffits

Balanced Mix Visible front drive turret, sleek discreet garden cameras

Preferred Mounting Height

About 10 ft / 3.0 m (Sweet Spot) Out of reach; shallow 25° angle captures clear faces

About 8 ft / 2.5 m (Porch Level) Best facial detail; requires anti-vandal IK10 metal casing

About 11.5 ft / 3.5 m (Gable Apex) Broad yard overview; risk of downward "head-top syndrome"

What Matters Most to You?

Facial Identification (DORI Standard) Admissible police evidence at 10m to 15m

Vehicle Number Plates High shutter speed to stop motion blur on headlights

24/7 Color Night Vision (ColorVu) F1.0 super-aperture without grainy black & white infrared

Preferred Cable Connection

Hardwired Cat6 PoE (Trade Standard) Power & 4K video on 1 cable; immune to Wi-Fi jammers

Wi-Fi / Battery Cameras Convenient, but requires periodic charging & strong 2.4GHz

⚠️ Engineering Blind-Spot & IR Glare Prevention:

1. Downpipe IR Wash: Ensure Camera 2 on the driveway is positioned at least 450mm away from black rainwater downpipes to prevent white infrared night-time glare.

2. Cross-Fire Overlap: Camera 3 (Side passage) and Camera 4 (Rear patio) must overlap coverage zones by at least 15% to eliminate blind corridors beneath ladders.

3. ICO Boundary Masking: Digital privacy masking should be applied to prevent recording across neighbour boundaries on the shared party wall.
