I am looking for opinions on wireless secutity cameras. I want ot
mount one on my house/garage and be able to view it on my TV. Is that
possible? What is the range when hooked-up like I want it? Do they use
batteries, if so, how long does the battery last?
Any other info is appreciated.
I've used the analog cameras for years, but now I'm switching to IP
cameras. The IP cameras attach to your network hub (by plug or
wireless) and get their power and send a/v all over simple and cheap
cat5 cable, or wireless. Then you use your computeer to view/listen/
record, etc. or take the computer video to a regular TV. I like IP
distribution over analog, picture quality is MUCH better, multiplexing
multiple cameras on the screen is a snap, recording to hard drive,
etc. For the analog cameras you can modulate their outputs onto
unused cable channels then watch it on any TV in the house just by
switching to that channel, you would need an RF modulator to do this
(but I still prefer IP distribution over my LAN). Good RF modulators
are not cheap, and finding unused cable channels on your in-home video
wiring is getting harder. Or you can go directly into the video-in on
one set with an analog camera. Wired cameras are best as there is no
battery, you can power it by injecting DC onto the coax or by running
video cable that has power and video, wired IP cameras use cat5. Many
cameras also offer audio. Batteries dont last very long in my
experience with any wireless camera, especially in winter. If you
mount the camera high, changing batteries is an ordeal. The quality
of the lens and size of the ccd will determine picture quality, if you
want the camera to be useful at all at night then you will need an
infrared illuminator that can throw the distance you need to cover,
again more argument to not use batteries and IR illuminators draw even
more current. IOW cheap analog cameras are a waste of money and
quality horrendous. Wireless range is usually 150 feet max with
wireless, wireless analog cameras are also not secure especially if
all your neighbors are also using your frequencies, they can easily
tune in your cameras.
I would check out Fry's electronics and see the IP cameras and just
feed them to your home computer network (be it wired or wi-fi).
Some are 200 feet and some are 400 feet. More than one camera requires a
scanner which can plug into your tv video jack. I bought a little color
TV for 60 bucks to view the cameras. A 'REAL" security monitor is 200
bucks and black and white at that.
Sam's club has several security camera kits.
