A Very High Crime Area With Daily Robberies, What Cameras Or Strategies Would You Recommend In Night Time Conditions?

I live in a very high crime area with daily robberies.    What cameras or strategies would you recommend that minimize motion blur (fast shutter speed) in night time conditions?  I will probably need to install somewhere between 6 and 10 cameras.  I also want a few cameras that will take video far away (200-600 feet away ) if possible

I made this its own discussion so more people can see it and help.

Motion blur should not be a significant direct problem since you can simply adjust settings to 1/30s, 1/60s, 120s, etc. depending on how the objects in your scene are moving.

The indirect problem may be how dark or noisy the images might become once you increase the shutter speed.

Any idea how dark the area is? Do you have any cameras currently installed that could give us a sense of the light level / layout?

And how important is color to you? That is where it could get hard / expensive but b&w video using IR is pretty easy to achieve.

Assuming you don't have any current cameras in place, my recommended strategy is to start small and simple to avoid buying twice.

Install a VMS and a few value-minded cameras with built-in IR to observe your home's perimeter. Play with and tweak the cameras' settings to learn their strengths and weaknesses. This will demonstrate what you need to view farther down the street, which will be more difficult and expensive. Add additional upgraded cameras when ready.     

Another strategy is to move.

Strategically have to put the cameras in highly visible places so these thugs know they are being watched. Just make sure your placement is not somewhere easy to be reached/vandalized.

Then after the psychological threat from the cameras' presence, I would personally give additional layer of security by adding visual white light when a person is entering the area of interest, that would be easier by installing those motion activated lamps. This will also help with the camera's ghosting image I believe, unless you want to maintain the cover of darkness around your perimeter then that's gonna need a different approach all together.

Off course using more sensitive image sensor on the cameras will definitely help, different brands use different terms: dark fighter, starlight, etc...

Initially, I would think that using a call down system using the following:

- A camera with line crossing or even basic motion analytic

- An outside speaker (or more)

- Create 10 or so separate voice recordings, put them on an SD disk, put the SD disk in the camera

- Make 10 "zones" randomized across the field of view to measure line crossing/motion

- Link each of the 10 "zones" with a different voice recording

You now have a cost effective method of letting people know they are being watched. Of course, you can always add to that, including an NVR to record the activity, or have a central station monitor the cameras, but the very basics are there.

If this is in California depending on the nature of the crime thieves are not concerned about being recorded and for good reason.
