The battery is a 3.7V, 6700mAh, 24.79Wh using 2 x LG 18650, 3350mAh cells. In theory, it should be replaceable by a smartphone repairer with a heat gun and spludger.
The charger (one for two cameras) is a standard 5V/2A micro-USB so as long as you have a spare ‘small’ head cable, you can use any charger. It will accept 5V/3A – the maximum over micro-USB.
In two weeks of testing it (5-10 events per day and two to three live views), it used about 20%, so this should last about 2.5 months.
I have read other reviews that claim they use of between 1 and 2% per day (100/50 days) with is about 3/1.5 months.
Recharge times are about 6 hours at 2A and 4 hours at 3A. The LG batteries are particularly good and will handle 3A charging.
PIR (claims sensitive to 7.5m)
PIR detects heat changes that is interpreted as motion. In our tests, it was reliable to about 4 metres with the caveat that we are testing in Winter at 9-11°.
The 2MP, ¼-inch (4.5mm diagonal, 3.6 x 2.7mm, 16:9) progressive CMOS sensor is used by dozens of security cameras. If it is the sensor we believe it is, it has larger 2.2um pixels coupled with an f/2.2 aperture (for distance and fixed focus). This should be good for low light, although it needs IR LED illumination.
Subjectively you can’t get great pictures 1K pictures from a ¼” sensor.
You can view and record up to 4 cameras at the same time through the included Mydlink app.
Night vision – claims up to 7.5m
It has four LEDs and the practical distance is about 2 metres.
I love the flat magnetic back (like the Arlo Pro 2). It means you can move it easily around placing it on metal poles, door frames, rainwater pipes etc.
Otherwise, it has a half golf ball mount and a ¼” tripod style mount.
The first number 6 means no ingress of dust; complete protection against contact (dust tight). The second number is water projected by a 6.3mm nozzle against the enclosure from any direction shall have no harmful effects. While not waterproof it is weatherproof and should stand up to rain, snow and dust.
I wish all manufacturers would stop promoting clear two-way voice. It is at best echo ridden and laggy sound. Respond, wait a few seconds, rinse and repeat.
Lag is caused by the signal having to go from the camera to the Hub, the hub to the internet to the cloud, the cloud to the internet and then finally to the phone – again rinse and repeat. Painfully slow – but then all brands are.
