Domestic CCTV usually is exempt from the Data Protection Act. However, if your camera covers, even partially, any areas beyond the boundaries of your property, such as neighbouring gardens or the street, then it will not be exempt from the Data Protection Act (DPA) under the domestic purposes exemption. This does not mean that you are breaching the DPA but it does mean that you might need to register as a date controller with the Information Commissioner's Office , annuall fee for which is £35, follow this link https://ico.org.uk/registration/cctv
This is because as the data controller for the footage, individuals do have the right to request a copy of it from you under the DPA, if you collect their personal data.

In this instance 'personal data' means any CCTV footage of other individuals that will be kept on your drive. I presume you want to record CCTV footage. In that case you will be 'collecting private individuals' personal data. However, s.36 of the Data Protection Act states "Personal data processed by an individual only for the purposes of that individual’s personal, family or household affairs are exempt from the data protection principles". Usually CCTV kits that come with hard drives do not keep recorded footage for longer than 30 days depending the size of the drive. So you probably should be fine as long as you do not disclose any footage of other people and also comply with the ICO's guidance on the use and storage of footage.
To answer your other question, technically you could request a copy of the footage from any other CCTV, if the owner of the CCTV is registered as a 'data controller' with ICO. But in practice, this is not so easy because you would need to satisfy the data controller that you are entitled to the footage. Such requests are common when its disclosure is required by law or made in connection with legal proceedings (e.g. cctv captured a crime or a road traffic accident) - see s35 of the Data Protection Act. It is unlikely that someone will knock on your door to request a copy of your cctv footage just so they can check how they look or walk in the footage.
However, in your case problems might arise if your CCTV camera is capturing your neighbour's garden/window and thereby compromising the privacy. They might complain. If not, then you should be fine as long as you film a small part of the road outside the property.

Pretty much. However, you should speak to ICO before you register. Don't simply register with them as it may be that you could be exempt from the DPA based on the 'domestic purpose' cctv. Because once you register you will have to comply with your obligations as a data controller.
