Ip cameras guide certified for Class I Division 1 and Zone 1 hazardous locations.
IP Security Cameras: Complete Buyer’s Guide
IP security cameras transmit video over a standard network connection, enabling high-resolution digital recording, remote access, and integration with video management software (VMS) across any network — from a single office location to a multi-site enterprise. This guide covers the camera types, key specifications, and practical considerations for commercial and industrial deployments.
IP Camera Types
Ip Cameras Guide for Hazardous Locations
Dome Cameras
Dome cameras house the lens and sensor in a compact dome enclosure, making them vandal-resistant and unobtrusive. They are the most common choice for indoor commercial environments — retail stores, offices, hotels, schools, and warehouses. The dome form factor obscures pan direction, deterring targeted vandalism. Browse IP dome cameras →
- Best for: Indoor ceilings, covered outdoor mounting points, retail and commercial sites
- Field of view: Wide-angle lenses (90°–120°) for area coverage; vari-focal models allow zoom adjustment post-installation
- Vandal resistance: IK10-rated models resist impacts; stainless steel trim versions for harsh environments
Bullet Cameras
Bullet cameras have a cylindrical form with integrated IR illumination for night vision, making them the go-to for outdoor perimeter and entrance surveillance. Their form factor is visible and acts as a deterrent. Built-in sunshields protect the lens from glare and rain.
- Best for: Building perimeters, car parks, entrance monitoring, long-distance outdoor surveillance
- IR range: 30m to 80m depending on model; some use white-light supplemental illumination
- Weatherproofing: IP66 or IP67 rated for full outdoor use
PTZ (Pan-Tilt-Zoom) Cameras
PTZ cameras allow remote pan, tilt, and optical zoom control from a VMS or controller. A single PTZ can replace multiple fixed cameras across a wide area. Auto-tracking firmware locks onto moving subjects; presets store key positions for patrol tours.
- Best for: Large open areas, car parks, campus perimeters, ports, and rail yards where active monitoring by operators is needed
- Optical zoom: 20x to 36x optical zoom for long-distance subject detail without digital degradation
- Features: Auto-tracking, patrol tours, preset positions, wiper options for weather
Box / Modular Cameras
Box cameras separate the camera body from the lens, allowing selection of the exact lens for each application — from wide-angle fisheye to long-range telephoto. Used in traffic monitoring, license plate recognition (LPR), and specialist applications where the optimal focal length varies.
- Best for: License plate capture, traffic monitoring, specialist surveillance requiring specific focal lengths
- Lens compatibility: CS-mount and C-mount standard lenses; varifocal and fixed focal options
Key Specifications to Compare
| Specification | Options | Guidance |
|---|---|---|
| Resolution | 2MP (1080p), 4MP, 4K (8MP), 12MP | 4MP–4K for most commercial; 2MP adequate for close-range access points |
| Power | PoE (802.3af), PoE+ (802.3at), 12V DC | PoE simplifies installation — single cable for power and data; PoE+ for PTZ and IR cameras |
| Compression | H.265+, H.265, H.264 | H.265 reduces storage and bandwidth by ~50% vs H.264; choose H.265 for multi-camera systems |
| Low Light | IR (monochrome), white light, starlight colour | Starlight CMOS for colour night video; IR for discrete night monitoring |
| Wide Dynamic Range | 120dB WDR, True WDR | Essential for entrance monitoring (bright outside, dark inside) and backlit scenes |
| Storage | NVR, cloud, onboard SD card | NVR for reliability; SD card for edge recording backup; cloud for remote access |
| Integration | ONVIF Profile S/T/G | ONVIF Profile S is the baseline; Profile T adds H.265 and metadata; choose ONVIF for any VMS compatibility |
| Analytics | Motion detection, line crossing, intrusion, LPR, face detection | Edge analytics reduce NVR load; AI-based analytics improve accuracy vs pixel-change detection |
VMS Compatibility: Why ONVIF Matters
ONVIF (Open Network Video Interface Forum) is the industry standard protocol enabling interoperability between IP cameras and video management software. An ONVIF-compliant camera works with any ONVIF-compatible NVR or VMS — Milestone XProtect, Genetec Security Center, Axis Camera Station, Avigilon Control Center, Hanwha Wisenet WAVE, and many others.
All Veilux IP cameras are ONVIF Profile S and Profile T compliant, giving you the freedom to choose or change your VMS without replacing cameras.
Choosing Between NVR, DVR, and Cloud Recording
NVR (Network Video Recorder)
An NVR receives video streams from IP cameras over a standard network. The camera handles video encoding; the NVR handles storage and playback. Best for installations where local storage is required for reliability and compliance. PoE NVRs with built-in PoE switches simplify installation by combining switching and recording in one unit.
Cloud-Managed Systems
Cloud-managed cameras (such as those compatible with cloud VMS platforms) store footage off-site and enable remote access without VPN configuration. Better suited to multi-site retail, branch offices, and smaller installations where on-site IT management is limited.
Hybrid
Many enterprise installations use local NVR storage with cloud backup and remote access — local storage for low-latency playback and compliance retention, cloud for disaster recovery and multi-site viewing.
Industry Applications
| Industry | Common Camera Types | Key Requirements |
|---|---|---|
| Retail | Dome, fisheye, PTZ | Wide coverage, WDR, people counting analytics |
| Warehousing & Logistics | Dome, bullet, PTZ | High ceilings, forklift-safe mounting, wide area coverage |
| Manufacturing (non-classified) | Dome, bullet, ruggedized IP | IP65/IP66 for washdown areas, vibration tolerance |
| Education | Dome, outdoor bullet | Vandal-resistance, wide angle for corridors, access control integration |
| Hospitality | Mini dome, covert | Discreet aesthetics, lobby and corridor coverage |
| Car Parks & Perimeters | Bullet, PTZ, LPR box | Long IR range, LPR capability, wide dynamic range |
| Light Industrial | Ruggedized dome, bullet | IP66, wide-temp range, IK10 vandal resistance |
How Many Cameras Do You Need?
Camera count depends on the area to cover, the level of detail required, and the field of view of each camera. As a rough guide:
- Small retail (up to 500 sq ft): 4–8 dome cameras
- Medium retail (500–2,500 sq ft): 8–16 cameras with NVR
- Warehouse (10,000+ sq ft): 8–20 cameras depending on aisle layout and ceiling height; PTZ for wide-area zones
- Office building (multi-floor): Dome per floor corridor + bullet cameras for entrance and car park
Use Veilux’s surveillance calculators to estimate camera count and field of view coverage for your specific layout.

Frequently Asked Questions
What’s the difference between IP cameras and CCTV cameras?
Traditional CCTV (closed-circuit television) refers to analogue cameras transmitting to a DVR. IP cameras transmit digital video over a network to an NVR or cloud system. IP cameras offer higher resolution, remote access, scalability, and ONVIF interoperability — making them the standard for new installations. Analogue CCTV still has a place in retrofit scenarios where existing coaxial cabling is reused with HD-over-coax cameras.
Do I need a separate NVR, or can cameras record internally?
Many IP cameras include an onboard microSD card slot for local edge recording. This can work as a standalone solution for simple applications but lacks centralised management, simultaneous multi-camera playback, and the storage capacity of an NVR. For systems with 4+ cameras, an NVR provides better management and reliability.
Can IP cameras work without internet access?
Yes. IP cameras operate over a local area network (LAN) and do not require internet access for local recording and viewing. Internet access is only needed for remote access from outside the site. For cloud-managed systems, an internet connection is required.
What resolution should I choose?
For most commercial applications, 4MP (2.5K) provides a good balance of detail and storage efficiency. 4K (8MP) is recommended when you need to crop and zoom footage in post-playback — for example, reading license plates or identifying faces at distance. 2MP (1080p) is suitable for access control points and close-range monitoring where bandwidth and storage are limited.
