BlackSys CH-100B Review
The BlackSys CH-100B is a dual channel dash cam that was released mid 2015 by the Korean company, Cammsys. This device consists of an elegant, discreet front unit that can record 1080p at 30fps, a tiny rear camera that records 720p at 30fps, and a sturdy 20ft (6m) cable to connect the two.
The CH-100B is an easy-to-install, easy-to-use camera that comes with many advanced features, such as true parking mode and low voltage cutoff. Optional external GPS/GLONASS and OBD modules can be acquired separately. The camera doesn’t have a screen. It does support Wi-Fi though, so you can control it via an Android or iOS smart phone.
The front camera’s video quality is good, at day as well as at night time. The rear camera records fair video at day. It performs well at night too, provided the street is illuminated. However on dark roads, you won’t be able to see much as you don’t have headlights to enlighten the rear view.
The CH-100B can take memory cards of up to 128GB capacity. A card of this size will allow you to record more than 24 hours of front and rear video.
The front camera has four buttons: A large one to lock files in case you’d like to save the footage of an event (also called “emergency button”), a button to toggle Wi-Fi, and two buttons to increase and decrease volume. The camera has voice alerts and supports 21 languages.
Below the buttons there are four LEDs that indicate front cam recording, rear cam recording, GPS signal, and Wi-Fi connectivity.
Note that this camera is also available as a single channel version, which you can later upgrade to dual if desired.
You configure the CH-100B via Wi-Fi, using a smart phone or tablet. Apps are available for Android and iOS, and they are quite intuitive and straightforward to use. There are too many settings in the apps to list them all here, but a couple of the more notable ones include:
- Change brightness for front and rear camera (independently)
- Flip rear camera image horizontally
- Configure standby time for parking mode
- Set G-sensor sensitivity
- Configure cut-off voltage to avoid draining the battery in parking mode
- GPS: display speed in mph or km/h
- GPS: set time zone, set summer time
- GPS: turn off when in parking mode (saves battery)
- Set memory card capacity for each of: normal recording, events (G-sensor or button triggered), and motion detection (parking mode)
- Customize motion detection to whole screen or any portion of screen
You can also watch live video footage on your smart phone, however there is a delay of about 2 seconds, so there’s no point in using the BlackSys as a backup camera for parking. Also, a rear facing dash camera should be mounted high on the window, while backup cameras are ideally mounted at about the height of the bumper.
To summarize, the BlackSys CH-100B has a great form factor, lots of useful features, and an excellent app. Video quality isn’t perfect, but it’s okay for a two-way system. While this camera is still rather new, it appears to be very reliable so far. Also, it is easy to install and use, and post sales customer support is excellent — making the BlackSys CH-100B a recommended buy, and one of our favorites for 2016.
BlackSys CH-100B Video Samples
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.
Day Time Front Video Sample
Front video quality is good during the day time, however license plates are only readable when close or stopped at a traffic light.
Day Time Rear Video Sample
Rear video quality is fair at day. License plates are readable when stopped/close. Note that this video is inverted horizontally (this can be configured in the camera’s settings).
Night Time Front Video Sample
The front camera is very light sensitive, resulting in good night video quality. License plates are readable when close.
Night Time Rear Video Sample
NIght video quality is fair for the rear camera, although somewhat fuzzy. Again, you’ll be able to read license plates only when close. Note that this video is inverted horizontally (this can be configured in the camera’s settings).
