A wired dashcam keeps footage on its memory card. A wireless one adds Wi-Fi or 4G to get it off. A fleet that must see incidents as they happen needs 4G. ## Key takeaways - "Wireless" describes how footage leaves the camera, not how it is powered: both types run on vehicle power. - A wired (offline) dashcam stores video on a memory card that someone has to collect. - A Wi-Fi dashcam sends footage to a phone at the vehicle; a 4G dashcam adds live view, remote download and alerts. - Nine of the ten dashcams in our range have 4G; the tenth, the B5, has Wi-Fi. A wired dashcam saves footage only to a memory card that someone collects by hand. A wireless dashcam adds Wi-Fi or 4G, so footage and alerts reach a phone or a fleet platform. Both take their power from the vehicle. For a fleet that needs to see an incident while the vehicle is still on the road, a 4G dashcam is the one to choose. "Wireless" suggests a camera with no cables. In practice it describes how the footage leaves the camera. We do not sell an offline-only dashcam: nine of the ten models in our range have 4G, and the tenth, the B5, has Wi-Fi. ## How each type works - **Wired (offline) dashcams** plug into vehicle power and record to a microSD card. To see footage, you remove the card or connect the camera to a computer. - **Wi-Fi dashcams** also record to a card, and connect to a phone at the vehicle. The [B5](/product/b5/) works this way, with no SIM card. - **4G dashcams** have their own SIM card and connect wherever there is mobile coverage, sending live video, clips and alerts to an app or a fleet platform. ## Key differences | | Wired (offline) | Wi-Fi | 4G | |---|---|---|---| | Power | Vehicle power | Vehicle power | Vehicle power | | Footage access | Remove the card | Phone at the vehicle | From anywhere with coverage | | Live view | No | At the vehicle | Remote | | Alerts to a manager | No | No | Yes, with a clip | | GPS tracking | Depends on the model | Not on the B5 | Yes | | Running cost | None | None | A data plan: about 1.1 GB a month in our worked example | ## What a 4G connection adds 1. **The clip arrives by itself.** When an alarm fires, the device uploads a short clip, and the manager sees the event and the footage together in the platform. 2. **Footage survives the camera.** A clip that has been uploaded is still there if the camera or the card is damaged or removed. 3. **Nobody collects cards.** Finding one clip no longer means visiting the vehicle. 4. **Settings and firmware change remotely.** The A5, A3, A6 and A18 update over the air, and the D9's stream settings can be changed from the platform. ## Common misunderstandings - **"Wireless dashcams don't need power."** They do. A supercapacitor or a small battery only gives the camera time to save the last file when power is cut. - **"Wireless means no installation."** Wi-Fi and 4G dashcams mount and wire up exactly like wired ones; a 4G model also needs a SIM card. - **"4G uses a lot of data."** Recording uses none. Fifteen minutes of sub-stream live view and five 15-second clips a day come to about 1.1 GB a month. The [4G data calculator](/4g-data-calculator/) works out your own figure. ## Which model - **[D9](/product/d9-dual-lens-dashcam/).** 4G, 1080p road and infrared cabin lenses, ADAS and DMS, two-way voice. For taxis, ride-hailing and delivery fleets that want road and driver coverage. - **[WD02](/product/wd02-ai-dashcam-with-gps/).** 4G, up to four channels, optional ADAS, DMS and BSD, and IO and RS232 ports for a panic button or a sensor. For fleets wiring cameras into other equipment. - **[B5](/product/b5/).** Wi-Fi only: three cameras, viewed on a phone at the vehicle with no SIM or data plan. For vehicles that return to a depot each day. For four 1080p inputs, eight cameras or a hard disk, look at an [MDVR](/product-category/mdvr/). Compare our [4G models](/product-category/4g/) and [Wi-Fi dashcams](/product-category/wifi/), or [contact us](/contact-us/) for a recommendation. ## FAQ ### Do wireless dashcams need to be plugged in? Yes. "Wireless" refers to how footage is transferred (Wi-Fi or 4G), not to power. The camera draws power from the vehicle's 12 V socket or a hardwire kit. ### What is the difference between a Wi-Fi and a 4G dashcam? A Wi-Fi dashcam connects to a phone within range of the vehicle. A 4G dashcam has its own SIM card and connects from anywhere with coverage, so you can watch live video and receive alerts remotely. ### Does a 4G dashcam need a data plan? Yes. It needs a data SIM from a local carrier. Fifteen minutes of sub-stream live view and five 15-second clips a day use about 1.1 GB a month; tracking alone uses about 17 MB. ### Is a wired dashcam enough for a fleet? It records evidence, but someone has to collect the memory card after each incident. Fleets that need to see incidents as they happen should choose a 4G dashcam.
