The legal rules relating to the use of CCTV by private businesses in the UK are defined by the Data Protection Act 1998, (there are additional legislation that the Public sector has to follow) The regulator for the DPA is the Information Commissioner's Office (ICO) and they have published a Code of Practice for the use of CCTV. A Google search should get you a copy. There are also British and European Standards that the industry may/should follow. See the BSI web site for BS 8418:2010 and the BS EN 50132 series. There is no requirement for installation of CCTV in any particular business although Local authorities and Police may ask for the use of CCTV for some Licensed premises (pubs/clubs etc) although this should not be a blanket requirement Hope this helps Ilkie

Virtually every function is user programmable. You can set a preset based on light sensor (switches to different config when the camera switches into mono). All changes to the default set-up can be saved overall or as a preset if required From the manual:- "Configuration The Configuration page is used to configure the unit and the application interface. Making Changes Each configuration screen shows the current settings. You can change the settings by entering new values or by selecting a predefined value from a list field. Not every page has a Set button. Changes to pages without a Set button are set immediately. If a page does show a Set button, you must click the Set button for a change to take effect. Notice! Save each change with the associated Set button. Clicking the Set button saves the settings only in the current field. Changes in any other fields are ignored. Some changes only take effect after the unit is rebooted. In this case, the Set button changes to Set and Reboot. 1. Make the desired changes. 2. Click the Set and Reboot button. The camera reboots and the changed settings are activated. All settings are backed up in camera memory so they are not lost even if the power fails. The exception is the time settings, which are lost after 1 hour without power if no central time server is selected." The Starlight function is a sensor type (and video processing software) purchased and as built on specific camera models, so I do not think this can be turned off. We would need a lot more information about the existing configuration/set up, environment and operational requirement to help further. If you want to continue to use this range of cameras and get the best you can out of the technology, I would suggest you ask Bosch for a training course. They are normally offered free of charge (at least they are in the UK). Hope this helps Ilkie

We fit a large numbers of these cameras and have not experienced this issue. I would suggest that you set up your network to allow remote access and get in contact with Bosch Technical support so they can talk a look. Ilkie

This is 100% correct. You first thing you need to define will be the purpose of each camera. (monitor, detect or identify). For example, you can cover an entire football field with one camera, but will this provide usable video (yes if you want to see movement, no if you want identification)? The critical measurement is pixels on target, for example in the UK, 125 pixels per metre on target is regarded as adequate for identification. This will help you define lens size and recorded resolution requirements for a defined distance from the camera. Regards Ilkie

The VJD3000 decoder is end-of-life at the end of 2016. This unit will give you PAL composite video output at 4CIF via a BNC connector, so lower resolution than the native camera output Regards Ilkie

The 7000 mentioned is a generic term for the range. It includes an ultra low light version called the starlight (MIC-7130) which has a slightly more sensitive sensor but only offers 720p. You can decode the signal to PAL but you reduce the resolution You can record the RTSP or H.264 stream using third party AV, ONVIF compliant software or Bosch's own Video Client (BVC) software Hope this helps Ilkie

Try Bosch MIC 7230 dynamic version. Resolution is 1080p Contact me if you want video samples Ilkie

There are a number of high end camera systems that include people counting as part of their video analytic offering, Bosch being one. Some offerings are quite basic but using APIs, specialist software can provide a greater choice of functionality. The accuracy of such systems relate to where the camera is installed to view the surveillance area. As you would expect, directly overhead is best and face on with shallow camera angles being the least accurate. Hope this helps Ilkie

Interesting approach. Can you let me know how you dealt with using solid core cables on an overhead hanger wire and did you have any problems with earth differentials? Ilkie

I would suggest that as the main concern is the quality of the recorded image, you should only consider a system from the high end manufacturers such as Bosch, Axis, Avigilon, etc. The quality and set-up of of the installation is critical and for high risk projects only consider purchasing a system from a professional installation company. Then you can detail exactly what you need to see (in writing), this is known as the operational requirement, and this becomes part of the hand over and commissioning document. It is unlikely that with DIY or self-installation will get the best out of the system purchased. I would also suggest you contact your insurance company and the Police for further guidance to ensure that any system meets their requirements as well. Regards Ilkie

Probably the use of IP media converters over the existing fibre might be cheaper than replacing cable. A professional approach would be to use a new network switch with multiple SFP ports Regards Ilkie

It sounds like you need a professional job. I would suggest that you first document the operational requirement (what you want to see, for example (bodies/faces/number plates etc), what size image, what areas you need to view, in what lighting/weather conditions, how long you want to retain recordings, how you wish to see the images (live/recorded) and what do you want to do with the recordings when you have them download locally - remote view? Contact a couple of local installers and give them the document and tell them that they will be paid when they have demonstrate that their proposal meets the requirements. Do not get involved in discussing the number of cameras, which manufacturer or what technology should be used, the proof of a successful system is meeting the operational requirement, is reliable and easy to use. Please bear in mind that CCTV only records events. It does not prevent attack by determined individuals so look at the physical security of the site first. Hope this helps Ilkie

OK, with this type of of project, processing at the edge is a major design principle worth considering. These removes the requirement for transmitting streaming video as the requirement becomes the transmission of the meta data , a plate patch image and the overview. This provides for transmission on very low bandwidth links (like 2G/3G) and offer a degree of buffering the data. There are also applications which entirely store at the edge and only transmit on request or on hot list activation. The overall design concept relies on the customer's operational requirement for presentation of the information. Is it wholly reactive or is there a real time requirement as well? There are a number of database issues which also need to be considered but I would rather not discuss these on an open forum, but feel free to PM me with further details of the project Regards Ilkie

Hi I suspect that the permits you are referring to relate to installation. The issue is state laws on data retention for example (from google) " Virginia is set to become the first state in America to impose a very short data retention limit on the use of automated license plate readers (LPRs, or ALPRs). Under the bill, Virginia cops will now only be able to keep such data for seven days unless there is an active, ongoing criminal investigation. New Hampshire previously banned the devices outright, while Maine has imposed a 21-day limit. However, many jurisdictions nationwide, ranging from the New York State Police to the Oakland Police Department, have no formal data retention limit" I think the record for shortest retention mentioned and being discussed is as low as 72 hours. I would suggest that you check with your State legislator for the current situation at you location Regards Ilkie

Consider using WD Purple NV disks for NVR applications WD Red HDDs are designed for NAS applications Ilkie

We have undertaken many of these types of project. However, there are strict rules on this type of installation in many countries. First, can you give us an idea of where you are? Ilkie

Siemens now own the intellectual property of Molynx kit, so getting in contact with them might be a way forward. There is also a specialist CCTV repair company that may be able to help out as well. PM me if you need further details Ilkie

If there is no power on site you will need possibly dual solar/wind turbine. I would suggest that you might need a minimum of 2 cameras at each site (one static + one PTZ) Most reliable transmission being drop and insert fibre, but wireless is possible depending on the terrain. Ilkie

This might help http://www.renewablemotion.co.uk/deployable.html Regards Ilkie

Agreed 100% The correct solution will be multimode fibre utilising transceivers sourced from manufacturers who build for the transport sector. These will be tested for vibration and fluctuations in power. Try Comnet http://www.comnet.net/aboutus/its.html Ilkie

Security Dynamics are the UK’s Official distributor for Dahua products. Ilkie

There are only 5 approved distributors for Hikvision on the UK. see http://overseas.hikvision.com/en/distributionPartner.aspx?c_kind=43&c_kind2=45&c_kind3=53&c_kind4=276#maodian Ilkie

Just a couple of small points. The cable you have quoted is not fire resistant, it is low smoke sheath. CAT6 is probably over the top for this application, CAT5E will suffice for the camera runs from the switch. I would suggest that you record alternate cameras on NVR1 and NVR2 so that loss of one NVR still allows for recording in the area. I assume that you are in the UK, so the regulation you need to abide by will be the Data Protection Act 1998. The use of the system will need to be notified to the ICO (legal requirement) and storage in excess of 31 days is unlikely to be acceptable. Also regarding Hikvision product, check that the vendor of the kit will support you with warranty issues, firmware upgrades etc as Hikvision have formal distribution partners in most countries and grey imports may not receive the same level (or any) support. Ilkie

The maximum distance that standard allows for running an IP segment (cable run) is 90m for the fixed element and a 5m patch lead at each end (total just over 300 feet). PoE will not run 500 or 1,000 feet. (check the specification for the kit you are looking to use) Ilkie

I have very often gotten away with using BNC T's to pass the signal onto a matrix or yet another DVR. It works on most DVRs but not sure about when that would degrade the signal. I haven't viewed it on a scope but I do see a very acceptable image on both DVR output and the matrix output. There are no gaurantees when you try something unconventional, the thing is unless you are one of these techno-bores and have to understand every detail to demonstrate your technical prowess (in short a show-off) SIMPLY SUCK IT AND SEE If the centre piece of equipment can be switched to loop-through or Hi-z then the use of the 'T' piece will be OK. The end kit (only) needs to be terminated at 75ohm. If the kit cannot be switched in this way the video signal will be significantly degraded. Specifically the sync pulse will be reduced possibly causing the video from the camera not being seen by the DVR or monitor (likelihood will increase with age) and the fine details in the image will be reduced.
