Power through mount
This feature means that the power to the DVR (usually from the cigarette lighter) is supplied directly
through the mount on which it is installed, and not through a separate cable. The mount itself is usually made quick-release.
Actually, the power cable in such models is also available — however, it is connected to the mount, and not to the registrar itself. Thanks to this, such a wire can be easily fixed in a strictly defined position; however, even without special fixation, he does not particularly move from his place. This feature provides a number of advantages over the more traditional connection format. Firstly, the wire does not hang around the cabin and does not create inconvenience. Secondly, it does not need to be searched for and reconnected every time when installing the recorder — just install the device on the mount. The latter is especially convenient if the recorder needs to be removed and put back often — for example, if the car has to be regularly left in an unguarded parking lot, where there is a risk of theft from the passenger compartment.
The cable is usually connected to the mount using a connector with the ability to quickly connect and disconnect — in case the wire needs to be removed from the passenger compartment without removing the mount. At the same time, many models use a standard connector like miniUSB or microUSB, which allows you to use a third-party power cable if necessary (for exam
...ple, if the standard cable is lost or damaged). However, for a full guarantee, such details do not hurt to clarify separately.Processor
Model of the processor used in the dashcam
The term "video chip" is used mainly for devices with classic capabilities, "processor" — for advanced models with an abundance of non-standard functions. However, anyway, we are talking about the same component — the main computing unit, the characteristics of which directly affect the capabilities of the recorder as a whole. Knowing the model of the processor, you can find detailed data on it and evaluate how satisfied you are with a device based on such electronics. Of the most advanced modern chips, one can name, in particular,
Ambarella A7L,
Ambarella A12,
Novatek NTK96655,
Novatek NTK96660 and
HiSilicon Hi3516.
Battery capacity
The capacity of the internal battery installed in the device (see "Power supply").
First of all, the general purpose of the battery depends on this indicator. If the recorder uses a relatively modest battery, up to 500 mAh, this most often means that it plays the role of backup power in case of disconnection from the cigarette lighter (for example, in an accident when the on-board network failed). In such cases, you can not pay much attention to the capacity - as a rule, it is guaranteed to be enough for at least a few minutes of offline recording, and for continuous operation the device will still have to be connected to the cigarette lighter. But for a full-fledged (not “spare”) power, much more capacious batteries are required - at least 800 mAh, and ideally 1000 mAh and higher. The exception is ultra-compact motorcycle models that do not have screens and do not consume much energy - sometimes 200 mAh or even less is enough for them.
Note that theoretically a more capacious battery allows the device to work longer without recharging. However, in practice, comparing different models by this indicator, in fact, makes no sense: after all, the autonomy of the recorder also depends on its power consumption, and it is determined by a number of characteristics. Moreover, manufacturers sometimes select batteries of different capacities for different models just in such a way as to achieve more or less the same battery life.
