Question: I need your expert advice on the correct way to
set up a house surveillance that consists of:
- Four (steady) cameras around the house (color and
with audio) - [Xcams possibly ???]
- with 4 motion sensors that track any movement
passing through them but not the dog that's in
the yard. They will be installed on the fence.
- an automatic system that records the camera (in
my VCR for a few seconds) whenever the sensor that
corresponds to that camera is tripped (triggered)
- the cameras AND the sensors must be wireless (except
for the power wire of course)
- I also need to see the cameras signal on my TV and
switch between the four, with my tv remote. It sounds
like an easy set-up, but I am going to make
an international order and I want to be sure I won't miss
any of the things that must be ordered. Can you please
point out to me the items I have to buy with their full
names (or codes) if possible ?
Another question: I am under the impression that these
motion sensors do not come wireless. If yes, then is there
any way to make them wireless with another device that
connects on the sensor an the vcr commander ?
Can you give me some advices on Wireless Security
Surveillance Camera?Thank you very much in advance.
Answer:You need a good modulator. That way you can assign each camera to a
channel, and distribute them all to every TV in the house. I'm doing
that with 2 cameras. One at the front door (B/W for greated light
sensitivity) on channel 74 and one in back (color) on channel 80. Both
are wired cameras (fewer problems) and have audio. If the doorbell
rings, I can select channel 74 from any TV and see who's there. I'm
considering adding a motion detector here, It will be wired.
From what I've heard the wireless motion detectors are OK (little
chance of RF collisions), but if it's converted to X10 powerline
signals, there's too much chance of X10 collisions. I think there's a
receiver available that connects directly to a computer and adoids
that problem, but wired devices are more reliable.
