Vans and taxis need two cameras, trucks three or four and buses four to eight. Start from the views you would want after an incident. ## Key takeaways - Choose camera views by asking what you would need to see after an incident, then count. - Vans, taxis and cars: two views, the road and the cabin. - Rigid and articulated trucks: three or four views, adding the nearside blind spot and the rear. - Buses and coaches: four to eight views, covering the driver, each door, the aisle and the rear. - Four 1080p cameras use about 7.2 GB an hour, so a 256 GB card holds about 33 hours. A van, a taxi or a car needs two cameras: one on the road and one on the cabin. A truck needs three or four, adding the nearside blind spot and the rear. A bus needs four to eight, to cover the driver, each door, the aisle and the rear. The number comes from the views you would want after an incident, not from the size of the recorder. ## Start with the views List the questions a claim or a complaint would raise, and give each one a camera: 1. **What happened ahead?** A road-facing camera. Every vehicle needs this one. 2. **What was the driver doing?** A cabin camera, ideally infrared, which also allows driver monitoring. 3. **What was alongside?** A side camera on the blind-spot side of long or tall vehicles. 4. **What was behind?** A rear camera, for reversing incidents and rear-end collisions. 5. **What happened on board?** Door and aisle cameras on passenger vehicles; a cargo camera on delivery vehicles. ## By vehicle type | Vehicle | Cameras | Views | Equipment | |---|---|---|---| | Car, taxi, ride-hailing | 2 | Road, cabin | D9 (road and cabin) or A5 (road and rear) | | Van, last-mile delivery | 2 or 3 | Road, cabin, rear or cargo | D9 or WD02 with one external 720p camera | | Rigid truck | 3 or 4 | Road, cabin, nearside, rear | D9 or WD02 with two external cameras, or a WD12 | | Articulated truck | 4 | Road, cabin, both sides or side and rear | WD12 with the BSD option | | City bus, school bus | 4 to 8 | Road, driver, each door, aisle, rear | WD10 or WD11, with passenger counting if needed | | Waste, construction | 4 or more | Road, cab, kerb side, rear or hopper | WD12; WD10 for more than four cameras | ## Two cameras: road and cabin For taxis, ride-hailing cars and vans, a dual-lens dashcam covers the road and the cabin. The [D9](/product/d9-dual-lens-dashcam/) records both in 1080p, with an infrared cabin lens and ADAS and DMS alerts. Where the rear matters more than the cabin, the [A5](/product/a5-dual-lens-dashcam/) records the road in 2K and the rear in 720p. ## Three or four cameras: trucks A truck adds the two places its driver cannot see: the nearside and the rear. There are two ways to reach four channels: - **A dashcam with extra cameras.** The D9 and the [WD02](/product/wd02-ai-dashcam-with-gps/) have two built-in lenses and take two external 720p cameras. Apart from power, the only cabling is to those two cameras, and the D9 ships with one rear camera on a 5-metre cable. - **A four-channel MDVR.** The [WD12](/product/wd12-mini-dual-sd-card-mobile-dvr/) records four 1080p inputs. Blind-spot detection through a [BSD camera](/product/bsd-camera/) is an option on it. ## Four to eight cameras: buses Passenger vehicles need the driver, the doors and the aisle as well as the road. The [WD10](/product/wd10-mdvr/) takes four 1080p or eight 720p cameras and a hard disk of up to 2 TB. It can count passengers on one to four doors, but not while ADAS and DMS run, and each counter uses two channels. The [WD11](/product/wd11-mdvr/) takes the same number of cameras, records to two SD cards of up to 256 GB each and counts with 3D binocular sensors. ## Check storage before you add cameras Each 1080p camera records about 1.8 GB an hour at our standard bitrate of 4 Mbps, so four cameras use about 7.2 GB an hour, and a 256 GB card holds about 33 hours of four-camera video. Recording the side and rear cameras at 720p brings that down to about 6.3 GB an hour. Work out your own setup in the [storage calculator](/dashcam-storage-calculator/).

A delivery van needs two or three cameras. A road camera and a cabin camera are the base; add a rear or cargo camera if reversing damage or load disputes are common. ### How many cameras does a truck need? A truck needs three or four cameras: the road, the cab, the nearside blind spot and the rear. An articulated truck may use both sides in place of the rear. ### How many cameras does a bus need? A bus needs four to eight cameras, depending on its length and the number of doors: the road, the driver, each door, the aisle and the rear. ### Can I start with two cameras and add more later? Yes, if the equipment allows it. The D9 and WD02 take two extra cameras, and an MDVR has spare inputs until all of its channels are used. By Kumar Saurabh, Head of Overseas Business, SKYWONDER.
