How can you disable CCTV cameras?
StepInspect the camera close-up. This will give you an idea if the camera is hard-wired or wireless. A wireless camera will usually be portable and contain a battery while wired camera will obviously show signs they are connected to the structure for power.StepRemove the battery or power source. If you suspect the unit is wireless, try to locate a battery compartment for removal. If the unit is wired, the power lines running to the camera will have to be severed.StepDisable the camera using a laser. If a power source cannot be determined and you don't want to destroy the camera, a laser pointer is your best bet. These devices are cheap and can temporarily disable the optics within surveillance cameras.If you have any other questions about CCTV and would like to get definitive answers on all of your CCTV questions then don’t hesitate to get in touch and we will be more than happy to help.Source: How to Disable a Surveillance Camera

How does the New Horizons spacecraft manage to take a sharp photo of Pluto while traveling at 31,000 MPH?
All the answers mentioning blurring is relative to distance are wrong. Blurring is proportional to speed and inversely proportional to the field of view of the camera. Now Imagine if you photograph a plane in flight, if the plane appears as a small speck in your photo it will look sharp, but if you zoom in such that the plane fills the frame. You are going to get a blurry mess unless you track the plane or use a very high shutter speed.Now let's look at the early new horizons image. Each pixel is said to be 2 miles new horizon is traveling at 31000 mph or 8.7 miles per second (assuming worst case scenario where the camera is pointing 90deg to the velocity vector) we can see that at 2 miles per pixel it the image would move 1 pixel every 0.23 sec.So to get a sharp image you will need to keep your exposure time significantly less than 0.23 seconds or pan the camera to reduce the apparent relative motion.At closest approach would be the worst case where the resolution is highest and the apparent motion is highest. Additionally Pluto's sunlit surface is about as bright as an office hallway, so it will be a challange to achieve a high enough shutter speed.Ultimately it is probably a combination of both reducing exposure time and relative motion.To reduce exposure time they could use a faster lens, more sensitive sensors, shoot only in black and white, use multiple exposures, use rolling shutter. As for reducing apparent motion, it's just panning the camera.Hopefully someone from the team can give as a definite answer but those are some options.
