Nexar Beam4 Dash Cam

Beam4 records the road in 4K at 30fps through a Sony IMX678 sensor at F1.7, and watches the cabin at the same time. LTE is built into the camera itself, so with an active LTE Protection Plan it sends alerts, streams live and backs up clips on its own, with no phone to tether and no Wi-Fi to find. It ships with 256GB of storage built in.

Yes. Beam4 has two cameras in one unit: a 4K road camera facing the road ahead, and a cabin camera facing inside the car. The cabin camera records at 1080p at 30fps. This is the interior camera, not a rear camera. A rear camera is a separate accessory you can add.

Yes. The cabin camera uses an RGB IR sensor with 940nm infrared night vision, so it keeps recording a usable picture inside the car after dark without lighting up the interior while you drive.

The road camera covers 146 degrees diagonally and the cabin camera 132 degrees diagonally, both measured corner to corner.

Connectivity is built into the camera, so it does not depend on your phone or your home Wi-Fi. That is what lets Beam4 alert you, stream live and back up footage while you are away from the car. Connected features need an active LTE Protection Plan.

Beam4 keeps watching after you walk away, powered by the OBD cable in the box. It detects motion and impacts around the parked car, records what happened and sends the alert to your phone. With an active LTE Protection Plan you can also open a live view and check on the car yourself.

No. Beam4 does not use a hardwire kit. It powers through the OBD cable included in the box, which keeps the camera supplied while you drive and while the car is parked, so 24/7 protection works without buying anything extra or wiring anything in.

Beam4 reads your car battery directly, which the rest of the Nexar range does not, so it can manage its own power draw rather than guess. That protection against draining the battery is built in and tested, and it works from the OBD cable in the box with no hardwire kit involved.

Yes. Beam4 records three audio channels alongside the video, capturing sound from inside the car and from outside it.

You set one angle, not two. Both lenses move together, and the cabin lens has a 20 degree tilt built into it, so once the road view is level the interior is already covered. It makes setup quicker than aiming two cameras independently.

Yes. Beam4 is built to operate from 14°F to 158°F (-10°C to 70°C), so it handles both summer heat in a parked car and winter cold.

Yes. Beam4 supports the Nexar rearview camera, which adds a view of the road behind you to the road and cabin views the camera already records. It is covered by your LTE Protection Plan at no extra cost: there is no second subscription, and the price of your existing plan does not change.

Beam4 comes with a 256GB card already fitted, so there is nothing to buy, choose or set up before you start recording. Footage records in a loop and the oldest is overwritten first, while clips from an incident are protected so the loop cannot erase them. With an active LTE Protection Plan, important clips are also backed up to the cloud.

With an active LTE Protection Plan you can see the vehicle location and open a live view from the camera. If the car is taken while the camera still has power and signal, you can pass that to the police to help recover it.

Beam4 mounts on the windshield behind your rearview mirror, out of your line of sight. Setup is the mount, the OBD cable and the app, with no wiring and no fuse boxes. That is the whole install, including parking mode, so there is nothing to add later. There is an installation video on this page.

The plan is what the built-in LTE reaches. It turns the camera from something that records for you to watch later into something that tells you what happened while it happened: live view from anywhere, real-time alerts for impacts and break-ins, vehicle location, cloud backup of important clips, and 24/7 parking protection. It also covers a rear camera if you add one.

Beam4 keeps recording to its own 256GB storage without any plan, and you can watch and save that footage. What needs an active plan is anything that has to reach you remotely: live view, real-time alerts, vehicle location, cloud backup and 24/7 parking protection. Basic is free, so the camera is never unusable.

Every Beam4 starts with a free 30-day trial of full protection, with no credit card required. After that you can keep full protection for $9.99 per month, or pay $95.88 for a year, which works out at $7.99 per month and saves $23 against paying monthly. You can also stay on Basic, which is free.

Yes, you can cancel at any time. Full protection stays active until the end of the period you have already paid for, and you will not be charged again after that. The camera keeps recording to its own 256GB card either way.
