Security Camera Suggestions?




teckblood


I live in the US, and am interested in setting up security on a property in honduras; here is what I need:

⢠10-15 outdoor/indoor cameras covering 24 acres
⢠preferred wireless if install is easier
⢠cameras/video must withstand 'hurricane' weather
⢠able to be viewed via computer while im in the states
⢠ability to move cameras remotely (in the US)
⢠backup on dvr or online database where I can access it via web
⢠separate power supply as power goes out on occasion

any suggestions? I would like to install it myself as I considered myself pretty tech savvy and am already spending lots of money on the equipment itself. Thank you.



Answer
That's a helluva system you want. I'm in the UK and can't advise on specific USA gear, but here are a few pointers.

Wireless is prone to being jammed, as your having to power the remote cameras anyway it's usually easier just to get cable that incorporates the coax or twisted pair for the video signal. 100% secure if buried. If you want PTZ (Pan, Tilt, Zoom) you will need a separate multicore cable for that. If you have long cable runs AC is better than DC, and boosters on your PTZ cable.

The cameras and housings can withstand hurricane weather, what you fasten it to might not. Lighting poles well concreted in is the best (expensive) option. Don't forget these need to be very 'stiff' or you'll get camera shake. Over engineered is better.

To view over the web you need a server in Honduras that offers 'static' IP address. You then put this address into a web browser and you can view, download and save any footage, some allow camera control, but the system at the Honduras end needs to have it incorporated. You need a recorder with an internet connection, 16 inputs, the ability to add hard drives and incorporating camera control. These usually come with a secure web browser on disc or you can set them up for any web browser, obviously less secure, but they will be limited to just viewing, not controlling or being able to go into set-up like the secure, purpose made, web browser can.

Don't get a computer type recorder, they can be hacked and are subject to viruses, buy one that has dedicated firmware, impervious to either of the above.

You can, if you double the price of the installation, have battery backup, it's pointless just backing up the recorder (nothing is lost in a power down) you need to back up the whole system, including powering the cameras, another reason for not using wireless. A battery back-up will only last an hour or so, for full power backup you need a generator as well.

To do it yourself you need Knowledge of networking, for the camera control they all use one of the Cisco systems and you need to know how that works, in my experience they seldom work 'out of the box'. Even the simple wiring for the cameras is not strait forward, you will blow a camera if you wire it the wrong way round on it's power, you can't return these cameras if you do, that's why the best gear is only available to the trade.

It's probably better to start with a smaller system and build, don't forget you need one camera watching another camera when covering an area, otherwise anybody with an aerosol can of paint can avoid being filmed.

SECURITY CAMERA VS SECURITY LIGHT?




THOMAS W


I AM GOING TO GET EITHER A SECURITY CAMERA OR A SECURITY LIGHT. I CAN ONLY GO FOR ONE, SO PLEASE TELL ME WHICH TO GET. IT WILL EITHER BE A DUSK-DAWN FLOODLIGHT, OR A COLOUR OUTDOOR SECURITY CAMERA SYSTEM.

BEST ANSWER TOP POINTS.
THANKS



Answer
Firstly i couldent care less about the points,id give the advice anyway
The camera,will be good after the event,to help identify the culprits,but unless you dont ever sleep
and sit up and watch it forever,or have it alarmed to wake you up

So id go for the light,and the cost very little to run
