Use switching regulator
February 8, 2020 - 6:12pm

A 1A dc-dc step down switching regulator will solve the purpose .
Search for a switching module.

This powerful down regulator
February 10, 2020 - 9:51am

This powerful down regulator efficiently produces a fixed 12 V output from input voltages between 3 V and 30 V while allowing a typical output current of up to 2 A when the input voltage is close to the output voltage and offering typical efficiencies of 80% to 90%. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below the regulated voltage. 

The flexibility in input voltage offered by these regulators is especially well-suited for battery-powered applications in which the battery voltage begins above the desired output voltage and drops below the target as the battery discharges. The no-load quiescent will typically be between 1mA and 5mA for all possible combinations of input and output voltages

This powerful step-up/step
February 27, 2020 - 11:26am

This powerful step-up/step-down regulator efficiently produces a fixed 12V output from input voltages between 3V and 30V while allowing a typical output current of up to 2A when the input voltage is close to the output voltage and offering typical efficiencies of 80% to 90%. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below the regulated voltage.

The flexibility in input voltage offered by this regulators is especially well-suited for battery-powered applications in which the battery voltage begins above the desired output voltage and drops below the target as the battery discharges. Without the typical restriction on the battery voltage staying above the required voltage throughout its life, new battery packs and form factors can be considered.

Using Voltage Converters (Buck)
May 9, 2020 - 1:48pm

There are some advanced buck/boost converter modules are available in the market with various specifications. In past, I have used in a project for my GSM module in an organization, where I used to power my GSM module (5V) using my power adapter of voltages 15V for that purpose, I used a buck converter to step down the voltages to 5V as per my modules' requirement. If want to use this module, it'll better for the camera as its size is very small. Here I suggest you to contact SSLA for getting better assistance for your solution of this issue. Also you can buy parts and modules from SSLA.
