Solar recharging of IR Illuminators for home security

[sebastian]

Hi folks - brand new to solar here - we've got some home security cameras that, while they have their own IR illuminant in them, because of the size of our yard, it's just not enough to give a clear picture at night. What i'd like to do is set up a small solar panel connected to a 12v battery to keep the battery charged, and then connect said batter to a IR illuminator to boost the IR for the cameras. We have really rocky ground and i do NOT want to run underground cabling to power these.

This is uncharted waters for me, so looking for some help in configuring things appropriately. Searching for "12v solar battery charger" on amazon gives so many results i'm not sure which to focus on. If i'm looking at illuminators such as

does it much matter, or are any of them sufficient? Also not quite sure how to tie the illuminator into the battery - do they make a battery connector that terminates in a 1/4" plug in type connector?

Thanks in advance for the assist!

The "illuminators" (IR light sources) that you link to have a DC input at some combination of voltage and current. Normally that comes from the power brick AC adapter shown in the pictures.
But I see no reason that you could not use a battery OF THE SAME VOLTAGE to power the illuminator directly via that same connector.
How feasible it is will depend on what the power needs of the units are.
You might need to add in a DC to DC convertor or regulator to get from a common battery voltage to what the devices need.

The description says DC 12V and says 15W (~ 1.2A at 12V). So your battery and solar charger will have to deliver one amp hour per device times the number of hours they are on per day.

You might find it useful to get an inexpensive "solar lighting controller" to handle both the battery charging from the panel(s) and the timing of the light operation.
Having them on 24x7 is going to increase your system power requirement considerably.
