![]() And you'd still risk not being able to start your car when you get in it. So, you'd probably get a lot less use than that. That doesn't take into account the fact that most of these 12V-5V converters will shut off when the battery drains to 10V or so. (See note above about not being able to start the car on a partly charged battery).ħ20Wh / 10W = 72h. Now divide the capacity of the battery by the consumed power and you get the number of hours runtime - until the battery is completely discharged. It's probably ~90% efficient but I've ignored that. Why isn't it 12V x 2A? Because dashcams run off 5V and there's a 12V to 5V converter supplying the camera. The battery in my '17 Civic hatchback is rated 60Ah.Īt a guess, your dual-camera setup might draw 2A. A partly discharged lead acid battery can't deliver that 'CCA' (Cold Cranking Amps) figure that's written on the cover.įor fun, some rudimentary calculations. A stone-cold engine at -40° is going to cause the starter motor to draw a lot more instantaneous current (a few hundred amps) than an engine with warm oil that's only just been switched off when it's a summer's day. There's also the variables of whether you're starting the car from a cold or warm engine, and what the ambient temperature was. That's hard to say, without conducting a series of experiments, to see how much charge you could take out of your battery and still be able to start the car. It takes some muscle, pry from the sides. NOTE: There are wires on the TOP LEFT and TOP RIGHT corner that must be unclipped to get the panel out of the way, these can be accessed after popping the trim panel itself away from the dash. To have 100% easy access, remove the knee trim panel as described below. Interior fusebox is located at the driver's left knee area right above the leftmost kick panel. You may break a few installing rear dash cam.ĭASH CAM/HARDWIRE (OPTIONAL, Other models may apply) Locked or unlocked.īolt securing fusebox to car body is a ground Always gets battery power, car on or off.

Once done, the only wires visible will be 1-2" going to each camera. My specific dashcam runs 24/7 whether the car is on or off and automatically records accidents and motion when parked. It can be done in a much lazier way, but if you take the time to do the install properly it will come out VERY professional. Install time is 2-4 hours depending on skill level. This thread will detail the full install (with pics) as well as guide you through what fuses to use and how to wire things. ![]() I tried to be as detailed as possible, but some pics are low light and thus the quality suffers. I've had some questions posting in other threads so I figured it best to make a thread about it.
