Some of the benefits of cameras are the ability for some semblance of omniscience. As we get older, we become forgetful. Having the ability to play back the
day's feed can aid in delaying an early elderly breakdown (in my opinion).
There are myriads of types of cameras to choose from. With a dizzying array of resolutions and features, invariably some of the best cameras will have undesirable higher voltage requisites. If using a 12v battery bank, this means a step-up converter of some sort.
Other features such as PTZ, allowing a user to PAN, TILT, or ZOOM in/out with either a joystick or mouse can require additional wiring adding to possible unwanted future maintenance.
The PTZ camera shown below, one of three here presently, are all-steel construction and a thick tempered glass dome. The unit runs on plates and can spin incessantly in one or the other direction, as opposed to the cheaper units which can only go so far, then must turn back due to being comprised of wire construction. The unit also allows for 27x mechanical zoom (and an undefined software zoom resolution which is rarely relied upon because the latter usually results in depreciation of picture quality).
Below are seen two types of other cameras incorporated into the building in Springfield. The first type is a night-vision camera indicated by the IR's (infrared) which surround the actual lens. However the camera to the right offers the ability to manually focus on a particular point. Focusing into a spot, such as on the wall, allows for the increased fine-tuning of the alarm or other function when the field is tripped. The cameras are also great for zooming to a point in the driveway where all that can be seen are stones and concrete up close and personal, until an automobile arrives, then it's 32 frames of a license plate.
Shown below is the backside of a DVR unit that will handle 24 cameras and 16 microphones.
With solar and a battery bank, ensures cost-free operation day and night.
The DVR seen below is being serviced, this DVR is a 4 Camera unit that
allows for up to 4 microphones.

During my first months at this location, came two young people at about
One of them came onto the porch and appears to have just been curious.
However, it is EXACTLY due to this visit that I shortly thereafter decided
to begin upgrading the security system to higher resolution units.
DVR's allow the privilege to play back a fast-moving fox, something I had
never seen before in the neighborhood. Without cameras I'd not know of the
family of possums that is no longer around. I no longer see the raccoon
family either, without cameras I'd never even know of a feral cat, possum,
and raccoon all on the porch at the same time! None appeared to want to
fight, although at one point the possum opened it's big mouth wide to show
the unimpressed raccoon his pearly whites.
I first began installing security systems about a decade or so ago, I
realized the importance to also have audio recording at all times also.
The notion was to curtail any communications errors with my customers. If
I cannot remember something, I simply play it back even if it were a week
or month ago.
Cameras put to rest conjecturing.
Security Systems allow for the editing or creating of one's own videos. As
a final note, if possible, the cameras should be powered on at all times
as opposed to only turning on when there's motion. If you have several
cameras appearing as really cloudy, it's possible that the morning dew did
not have a contender within the camera. As a perfectly timely example, I
have about half a dozen camera cases that allow the camera to be placed
within the box. The boxes are incorporated with a heater in the front and
a fan in the rear to aid in cooling when too hot and heating when too
cold. As it turns out, 1/3 of the cameras in and out of this building had
been off all night due to some changes being made with the power system
here. Also, it was needed to have a smaller DVR backup the main DVR.
Connecting the output of the Main DVR to one of the inputs of the 8 camera
DVR leaves 7 new spaces that future cameras can be connected. At
first the backup DVR was planned to be placed in the attic because it was
convenient, but then I realized how cold it was and quickly remembered
that in the Summertime it is unbearable up there. When the daylight
broke I was finished with the changes and re-activated the cameras only to
find a hazy blurry mess on two of the cameras, both of which were on the
South side of the building and both were outside cameras.
After the initial panic, it was deduced to be a fogged up glass front, and
after 20 minutes wait-time, the cameras were clear again. Lesson Learned.

The following is a concealed 12v microphone (very
sensitive) which is being sold for $35.00.
Although the unit comes with RCA connection already,
there are adapters here that will accommodate any need for the prospective
