Just to correct you a bit. With motion detection the camera remains on, but you only store clips when motion is detected. IMO a camera peering out of a window does not cut it.. The IR lamp will not work properly, I think you will get reflections and it is less visible to someone mooching around. Better imo to mount about 8 ft up and run the ethernet cable to the camera. If you go for wifi instead you only need a9v DC cable that you can safely run yourself.
Dave is the pro, I’m just the amateur.
From my perspective you need to apply the normal security rules.
a) What are you trying to protect?
Line of sight is important, but so are access to power and your network. Cabled PoE addresses both these issues in one bit of cable but you will need to look at distance, cable runs etc. Ideally you want something that can ‘look’ at the approaches to your shed. Too high is not good as you just get the tops of the heads of intruders. However, ensure that your camera cannot be stolen by mounting out of reach! I’ll leave Dave to talk about lenses etc, but good lenses come at a cost IMO a1080p camera is good enough.
[edit] Should have said I use Foscam. You might want to look at coupling with Zomeminder as its own software does not do tracking.
b) What are you trying to achieve.?
I’d be surprised if you are trying to ‘catch’ thieves or vandals. You are looking to deter. In this situation good locks and visible alarms help. IMO this also applies to security cameras. I find that zoom is rarely useful but tracking is a must. Nothing deters a potential thief more than a camera that auto tracks and has a big red ‘eye’ (the IR flood) looking at the intruder.
Then it all comes down to budget – do not go too cheap as then you get junk with no way of updating security holes in the firmware. You will also need to spend money on software such as BlueIris for Windows or go the Linux route with Zoneminder or iSpy . This route means you will need to brew your own tracking software. Expensive cameras such as Hikvision come with software and firmware solutions. (Dave can comment on tracking facilities in Hikvision as I do not know)
I personally use Foscam cameras (as I’m a tightwad) and a combo BlueIris JSON homebrewed software tracking solution. If I were starting over I would probably go the Zoneminder/Linux route – I believe Malc is an expert in this area.
I have four cameras coupled up to a standalone 1 Ghz P + SSD and these just about max out the cpu on this box. It handled two cameras easily but it is definitely labouring with four 1080p IP cameras. Soon be time for its own i3Brix box!
Try using a Neti pot Steve. (Basically use it to flush your sinuses with salty water). I started using it after getting a staph infection of a sinus following a dental extraction that went wrong. Cheap, and helped cure the staph infection quickly, but most noticeably for me it has halved the impact of pollen induced hay-fever.
It is a bit messy to use (nude in shower job) as you basically pour water into one nostril and drain it out of the other.
Slight divert, but it may be a useful tip if you want to make a faithful copy of any SD card.
Raspberry Pis are great but the constant writes/crashes takes its toll on SD cards. Through bitter experience I have found that frequent full backups is a must. The easiest tool to accomplish this is DiskImager. This little Windows based tool quickly makes a clone of your SD card and allows you to tuck it away on your PC. When you corrupt a card just throw it away and write the backup image onto a new card.
With all the nasties floating around it is going to get ‘interesting’ using old vulnerable software. I’m afraid the real choice is Windows 10 or Linux at the moment. The new features of Windows 10 coming this autumn are going to be difficult to find anywhere else.
July 3, 2017 at 4:09 pm in reply to: Windows 10 pc not recognising some USB and portable drives #9856You did not state your OS but I’m guessing it is Windows.
Windows has two major problems with usbs:
a) Further to BL’s post. USBs have an overload protector in software. which cuts out and deactivates the drive if it thinks too much power is being drawn (bit like a reusable fuse). Typically PVRs and other such power guzzlers are the problem. The easy solution is to unplug all your usbs and shutdown the Pc. Wait 30 secs then switch back on. start up Windows as an Administrator. Then plug in the USB equipment ONE AT A TIME. Allow windows to detect and install any necessary drivers before inserting further devices — rinse and repeat.
b) Sometimes you will also get old drivers causing Windows to get confused. The easiest way of dealing with this is to get shot of the lot! You need to follow the following steps
- Show hidden device drivers. link
- Look at the USB devices in Device Manager
- Remove ‘ghosted’ duplicate drivers (normally the HID mice and keyboards cause problems). I’m afraid you have to either use common sense over this, or be careful to do a full registry backup first. link. I’d recommend using the restore point option as it gives a little protection against malware activities. It isn’t hard to do this procedure but please work through it slowly and use common sense as it is possible to break things.
I’m afraid i now tend to be a bit blasé over this process, and delete all the USB drivers and start afresh. I’m not sure I’m brave enough to recommend this approach!
The only ones I can see having a good future are plumbers, electricians and soccer players!
You forgot to add politicians to that list ED!!
No – see Bob’s previous post. I see a lot of politicians making their way to the tumbril when the revolution finally kicks in!
The current regulations appear ambiguous and could be dependent on reports from Exovar. See this report by Rockwool (not exactly unbiased however). The Government no longer mandates requirements (as was the case in the past). The whole onus is now thrown onto the building developers/insurers.
Incidentally Government blame falls on the recent generations of UK politicians who kicked the whole reform into the long grass. link
The biggest changes were between 1945 and 1965. The rate of change slowed a bit in the next twenty years, but really picked up the pace in the following twenty. Big discoveries in things like automation, AI and machine learning were made in the early noughties but they took a little while to mature. I suspect the next twenty years will change the whole world out of all recognition, or completely destroy it.
I get quite worried at the future prospects for my grandchildren. I’m not so sure there is going to be much call for intellectual achievement in the future world. The only ones I can see having a good future are plumbers, electricians and soccer players!
Not uncommon to have BT problems with your phone. Try this.
“Engineers rarely get into trouble over walls that remaining standing, it is the ones that fall down that give engineers grief!”
There is always a contention between cost and over-design and that is why engineers always fall back on recognized standards and codes. Obviously your Liverpool engineer wasn’t so hot at reading the small print and notations!
I found your earlier remark interesting, and one I would echo and add ‘current standards and codes of practice’ to your comment on testing
” My own general view is that standardised testing is there for a reason and I don’t see any huge reason why this shouldn’t be followed”
This is certainly the case in many *counties with most other aspects of domestic building work. If you ever get involved in making a major extension to your house you may find that the Planners will insist on bringing the whole house up to the latest building regs for Environmental Standards. Strangely, and echoing Grenfell Tower a bit, this did not in my case extend to ensuring that the garage ceiling boards were fire-resistant (the pink ones). They are now!
*I believe that policies on upgrading domestic building stock are applied on a county by county basis and at the moment are dependent on the viewpoints of the County Councillors.
My guess would be that your car’s electrics are to blame.link
As the link says unless you can pin it down to a faulty component in your car there is not much you can do. Put the aid near to the various components of your car’s electrics and see which one causes the squeal – preferably removing it from SWMBO first!
I cannot comment on the Building Inspector’s relationship with the FRS, but I do know that the Inspectors are grossly overworked.
To the best of my knowledge we have just one Inspector to cover all the applications and inspections involved in a population of about 150,000. They have very little time to do anything except rubber-stamp stuff that is being built to already approved specifications. The days when inspectors would come along and poke around in footings appears to be long gone, and they never do things like check that buildings are actually constructed where they are supposed to go from approved materials. They are now heavily reliant on others such as NHBC to ensure that things are being built to a reasonable standard. I would guess that they are similarly heavily reliant on the expertise of others such as the FRS/Exovar for signing off on things like cladding and fire prevention measures.
It would not surprise me to learn that there are also very few Inspectors in the Rotten Borough of Chelsea.
In case you missed it, this BBC report covers the testing and approval for the cladding materials. Looks like Exova (54% Dutch owned – Tabasco BV) s going to have to answer a lot of very hard questions – especially with respect to their testing procedures and how any ‘desk-top’ analyses apparently ignored actual experience of high-rise building fires.
This is the actual GMail blog announcing the change. I’d infer that just like your ISP they will continue to scan for malware, and also phishing/known scams. I’d also infer that once you delete your email it will be erased – that is once the Government mandated retention for spying period is over. It would seem that Google will not be using your mail for its own purposes but they do not actually make that statement.
I think bullying is an inherent part of the ‘animal’ psyche. I was fortunate enough to go to a coed school which gave us males a small insight into female behaviour. Although the usual male ‘cock of the roost’ fights took place they were soon over and done with – both forgiven and forgotten, However the males used to look on with a degree of horror at the way females played cruel clique mind-games with one another. I gather that the advent of smart phone social media has made such ‘games’ a thousand times more effective and even more cruel than they were 60 years ago.
One Drive is another option if you do not want Google spying on all your activities. Incidentally Google are starting to react to their ‘spying’ reputation and have promised to stop scanning all GMails (and any other mail accounts accessed through GMail) link
I didn’t read your link, but I did see Google press releases, and it said “it would stop scanning email for the sake of adds” differences from we won’t scan.
If they stop scanning then then that’s the point of picking gmail/docs over any other cloud service. It’s the scanning that give customer value.
The dangers for your granddaughter are peer pressure and bullying. In the wrong environment school children can be little horrors in trying to cut down other children they perceive as ‘tall poppies’. Your daughter needs to be very sensitive to any signs of bullying. A change in school may be needed!
[edit] It is much easier to address with boys. When my eldest son joined school in the US he was about two years ahead of his year group (better UK education!), and was perceived as a ‘Nerd’ and ripe for bullying, but he is also very sporty (had his red belt in Karate, and excelled at ‘soccer’) so he also passed as a ‘Jock’ and definitely not ‘bully-bait’.
Parental attitudes have a huge impact on children being able to use their abilities to the full. Modern research now shows that educational achievements only have about a 30% dependency on their genetic make-up, the remaining 70% is completely shaped by the child’s environment. Diet and health are reasonably large factors in this, but parental attitudes and educational participation by the parents have by far the larger influence.
I guess some of this is probably a post-code lottery. but I have just witnessed one of my grandchildren progressing through the Play School period into the first years of proper schooling. I was pleasantly surprised at the amount of materials given to the parents which if properly used could result in the child starting school with a fairly sound idea of both reading and numeracy. Obviously those parents who are too busy/tired after working all day have to find a ‘second wind’ to do all this, but the primary school teachers say that there is a visible educational gap between those who do and those who do not take this time to encourage and support their children.
@Steve,while I generally agree with your point on SSD/brand loyalty, it is unfortunately worth doing a search on your mobo in conjunction with the SSD. For firmware reasons one of the Kingston 128GBs is highly unreliable when used in conjunction with a NUC – been there got the scars. Nothing wrong with the SSD it works fine with a Raspberry Pi, but it just kept falling over when used in the NUC. (apparently a known problem judging by the number of similar Google entries).
