2M Technology’s line of network IP dome cameras discreetly blend into any environment while delivering high-quality images. Ideal for indoor spaces, their compact and sleek dome shape makes them less conspicuous, serving as a silent deterrent against potential threats. With advanced features like remote access and easy integration into existing networks, these cameras provide a smart and efficient surveillance solution for modern security needs.
Network dome cameras house the lens and sensor inside a discreet, dome-shaped enclosure — offering resolutions from 2MP to 4K, vandal-resistant housings rated for physical impact, and Power over Ethernet (PoE) for single-cable install. Available in fixed-lens, motorized varifocal, and Starlight/WDR low-light variants for indoor and outdoor commercial installations.
A network dome camera is an IP security camera built inside a rounded, dome-shaped housing instead of the cylindrical body of a bullet camera. The dome shape makes it harder for an observer to tell which direction the lens is pointed, and the compact, low-profile design blends into ceilings and soffits rather than announcing its presence. Most commercial dome cameras also carry a vandal-resistant rating, meaning the housing is built to withstand a physical impact attempt without disabling the camera — a common reason they’re chosen for entryways, retail floors, and other areas the public can reach.
| Type | Lens | Best For | Tradeoff |
|---|---|---|---|
| Fixed-lens dome | Single fixed focal length, set at install | Budget installs where the field of view won't change | Field of view can't be adjusted remotely later |
| Motorized (varifocal) dome | Remotely adjustable zoom/focus | Sites where coverage needs may change after install | Higher cost than a fixed-lens equivalent |
| Vandal-resistant dome | Fixed or motorized, in an impact-rated housing | Publicly accessible areas — lobbies, retail floors, parking structures | Bulkier housing than a standard indoor dome |
| Starlight / WDR dome | Fixed or motorized, low-light optimized sensor | Areas with poor or inconsistent lighting | Higher price tier than standard sensors |
Indoor dome cameras typically use a lighter plastic or basic metal housing since they aren’t exposed to weather or casual impact — a good fit for offices, hallways, and retail sales floors. Outdoor and public-area dome cameras need an IP66-rated weatherproof housing to keep out dust and water, and an IK10 vandal-resistant rating to withstand impact from tools, thrown objects, or deliberate tampering. Before ordering, confirm the housing rating matches where the camera will actually be mounted — an indoor-rated dome in an exterior soffit will fail faster from moisture exposure regardless of its image quality.
| Resolution | Best For |
|---|---|
| 2MP | General area monitoring, budget-conscious indoor installs |
| 4MP | Standard commercial coverage with room to digitally zoom on playback |
| 5MP–4K (8MP) | Facial identification and license plate detail at longer distances |
Rule of thumb: 4MP is the practical minimum if you need to identify a face after the fact rather than just confirm someone was present. Starlight and WDR (Wide Dynamic Range) sensor variants are worth the added cost for entrances that face bright exterior light or need usable footage after dark.
Mounting height directly affects both coverage area and image usefulness. A dome mounted too high loses facial and license-plate detail even at high resolution, since the subject occupies fewer pixels in the frame; mounted too low, it becomes an easier physical target and covers a smaller floor area. Most commercial indoor domes are mounted 9-12 feet high for a balance of coverage and identification detail, while exterior domes over entrances are typically set lower — around 8-10 feet — specifically to keep faces identifiable as people pass beneath. Ceiling-recessed mounts also exist for a lower-profile install where the dome housing sits flush with a drop ceiling.
Network-connected dome cameras are endpoints that can be targeted by attackers if not properly hardened. Key risks: default passwords never changed, no firmware updates, cameras accessible from the public internet without authentication. Best practices per the NIST Cybersecurity Framework: change all default passwords before installation, keep camera firmware current, place cameras on a dedicated VLAN separated from business IT systems, and disable public internet access or secure remote access with a VPN.
Start with where the camera will be mounted and who might be able to reach it. Publicly accessible areas — lobbies, retail entrances, parking structures — call for a vandal-resistant (IK10) housing regardless of resolution needs, since a damaged or disabled camera provides zero coverage. Areas exposed to weather need an IP66-rated housing on top of that.
Next, match resolution to what you actually need to prove after an incident. If confirming that someone was present in an area is enough, 2-4MP keeps cost down. If you need to identify a specific face or read a license plate from camera footage, budget for 5MP or higher and place the camera closer to the path people or vehicles will actually take.
Finally, decide between fixed and motorized lenses based on how likely your coverage needs are to change. A fixed lens is less expensive and has one less moving part to fail; a motorized varifocal lens costs more but lets an installer (or, on some models, a remote operator) adjust the field of view after mounting without physically re-aiming the camera.
Analog CCTV cameras send a continuous video signal over coaxial cable to a DVR (digital video recorder), which converts it to digital and records it. IP cameras send already-digitized, compressed video over ethernet cable or Wi-Fi to an NVR or cloud platform. IP cameras offer significantly higher resolution (2MP to 4K vs analog maximum of ~1MP), easier installation using existing network infrastructure, and remote access over any network-connected device. They also support on-camera analytics, motion zones, and audio.
Yes. Network IP cameras record to an NVR (Network Video Recorder) on a local network, not to the internet. The internet connection is only required if you want remote viewing on a phone or laptop when off-site. Local recording and playback work fully on a closed local area network (LAN) with no internet connection. This is important for facilities with strict cybersecurity policies.
Coverage depends on building size, floor plan, and risk profile. A rule of thumb for interior coverage is one camera per 1,000-1,500 square feet of open-plan space. Key areas always requiring dedicated coverage: all access doors, main corridors, cash handling, server rooms, and loading docks. 2M Technology provides a free camera placement review for commercial projects based on facility drawings. Most office buildings in the 5,000-20,000 sq ft range require 8-24 cameras.
ONVIF (Open Network Video Interface Forum) is an interoperability standard for network IP cameras and NVRs. Most commercial IP cameras and NVRs support ONVIF Profile S or G, allowing cameras from different manufacturers to work together on the same NVR. However, advanced features (AI analytics, smart motion zones, automatic firmware updates) are usually only fully supported when cameras and NVR are from the same brand ecosystem (Hikvision, Dahua, Hanwha, Axis). For multi-vendor environments, verify ONVIF compatibility before purchase.
Storage duration depends on camera count, resolution, frame rate, compression (H.264 vs H.265), and motion-based recording settings. As a reference: 8 cameras at 4MP resolution, H.265, continuous at 15fps require approximately 100-144 GB/day. A 10TB NVR provides roughly 70-100 days of retention for this configuration. H.265 compression (current standard) uses about 50% less storage than H.264 at equal quality. 2M Technology calculates storage requirements for every installation and sizes the NVR accordingly.
