MAY 2019 UPDATE: The SG9663DC has been replaced by the newer SG9663DCPRO. The differences are minimal, the main upgrade being the rear camera lens. Video quality is still great, both at day and at night. The review below applies to both versions, except where noted otherwise.

Street Guardian SG9663DC / SG9663DCPRO Review

Released in November 2017, the Street Guardian SG9663DC is a high-end front & rear car camera. Taking a different approach than its competitors, Street Guardian didn’t aim to include as many cutting-edge features as possible. Instead, they focused on the basics: reliability, usability, and image quality.

Lets start with the latter: The SG9663DC records hands down the best video quality of all the dual channel dash cams we have reviewed so far. At a video resolution of 1080p (1920x1080) and 30 frames per second, the bit rate is 15Mbps for both the front and rear channels. The resulting video quality is of very good quality, with details such as license plates readable even as you’re driving by, whether at day or at night.

UPDATE: As of November 2019, the SG9663DCPRO now officially supports Wi-Fi. (Technically, the camera has always had Wi-Fi capability, but the smart phone app has only just been finalized.)

The SG9663DC comes with a 2″ screen that makes configuring the camera relatively simple, and also allows you to play back video footage on the spot. Of course, you can always pop out the SD card and play back the MP4 encoded videos on your computer, if you’d like to take advantage of a bigger screen.

As of 2019, the SG9663DC has been replaced by the SG9663DCPRO. While we aren’t a huge fan of Street Guardian’s model names becoming ever longer and more unwieldy, that’s the only (very minor) complaint that we have about this upgrade. The main difference to between the SG9663DC and the SG9663DCPRO is that the pro version uses a Sony IMX291 sensor for both the front and rear camera, while the “vanilla” version used an IMX323 for the rear cam.

Also, the SG9663DCPRO version includes extra cord and cable covers (items #25 and #26 in the accessories sheet below). Everything else stays the same, so we’ll just keep calling this camera SG9663DC in this review, for the sake of brevity.

With its stealthy wedge shape, the SG9663DC keeps a low profile on your wind shield. If you’d like to avoid attracting unwanted attention while parking in a sketchy area, the camera is easy to remove from its mount if you want to take it with you or stow it away. It even comes with a useful pouch to store it in while off duty.

The SG9663DC supports time-lapse parking mode, recording at a reduced frame rate until the car is turned on again. Street Guardian’s hard-wiring kit is called SGDCHW and it costs around $30 (see exact price on Amazon US / Canada / UK).

The SGDCHW hard-wiring kit taps directly into your cars fuse box. It allows you to select a cut-off voltage to keep the camera from draining your car’s battery. Additionally, you can also set a time limit after which parking mode will switch off automatically.

GPS logging is supported, and an external GPS antenna is included with the camera. Speed can be displayed in km/h or mph. A CPL lens is also included, to reduce reflections in the windshield when driving in bright sunlight.

Memory cards can be up to 512GB in size. Class 10 or above cards are recommended. It’s recommended to always format memory cards in the camera for them to function properly.

This camera comes with a memory card included. You can choose between 32GB, 64GB, 128GB, 256GB, 400GB, or 512GB SD cards. The smallest card (32GB) gives you just above 2 hours of total recording time, while a 512GB card allows you to record an impressive 37 hours of footage before loop recording kicks in.

Based in Australia, Street Guardian, are known not only for their highly reliable cameras and great attention to detail, but also for their outstanding customer support. We’re not connected to the company any way, but with several years of reviewing dash cams under our belt, we believe that Street Guardian are probably the brand with the highest customer satisfaction in the long term.

To sum it up, this is an excellent two-way dash cam for beginners and advanced users alike. If you’re happy to go without cloud connectivity that some more expensive brands offer, this is a highly reliable camera with the best overall video quality so far (as of November 2019). The built-in screen allows for ease of installation and operation, and its wedge-shaped body keeps it stealthy and discreet.

All this, combined with Street Guardian’s top-notch customer support, make the SG9663DC one of our favorite front-and-rear dash cams for 2019, and our TOP PICK for those who don’t need features like cloud connectivity and buffered parking mode.

NOTE: If you’re interested in getting a high-end front and rear camera but can’t quite afford it right now, check out Street Guardian’s SGGCX2PRO which is a single-channel dash cam that supports adding a rear camera later. You can order the main camera now, and get the rear cam at some point in the future.

For full original video quality, make sure to watch on full screen and select maximum video resolution (use the cog icon in lower right corner). You may have to rewind the video after changing the resolution.

Front video at day time is of very good quality. All details are clearly visible, and license plates of nearby cars are easy to read.

Rear video quality at day is also very good. License plates of other cars are easily readable by pausing the video.
